Buying Guide – Heaters

Posted on 10th October 201329th July 2021 by Charles Barnett

Last updated on 29th July 2021

There are various types of heaters available, each with their own set of advantages, disadvantages and uses for certain situations. For instance:

Need a low constant background heat? – a panel heater may be what you need
Need to warm an infrequently occupied room? – a wall-mounted fan heater may offer the best solution.

Each situation offers a unique heating challenge. In these days of ever rising heating costs, no one wants to waste energy and pay needless heating bills. Efficiency is definitely the watchword here and with that in mind we have put together a simple heater guide. It explains the different heater types and helps you select the best one for your overall heating requirement – saving you money, whilst keeping you warm.

Convection Heating

Convection heating works by passing the air over an element to warm it up and then circulating it back into the room. There are two types of electric heaters that utilize convection heating technology: convector heaters and panel heaters.

Convector Heaters

Convector heaters are a good choice for medium-sized rooms where an even temperature needs to be maintained. They provide heat fast, are very quiet and are light and easy to manoeuvre. There are free standing or wall mounted versions available, whilst many do both. Free standing convector heaters are great for using in temporary buildings and workspaces and when buildings are being refurbished.

Panel Heaters

Panel heaters are designed for smaller rooms requiring constant low-level background heat. Benefits include their slim, space-saving design and low running costs. Their unobtrusive size makes them particularly useful in bars, restaurants, clubs and hotels.

All our models of convector and panel heaters include a thermostat to control the temperature, as well as overheat protection which automatically turns the heater off if the warm air grill gets blocked.

Oil-Free and Oil-Filled Radiators

Radiators are somewhat misnamed, most of the heat that comes from them is actually by convection. Radiators heat the air that flows past them. As the air warms it rises away from the radiator and the colder air falls. This causes the air to begin to circulate around the room and the colder air is warmed as it passes the radiator.

Oil-Filled radiator

Oil-filled radiators have a large surface area, making them a great choice for heating larger sized rooms. Once the oil has been warmed up, electricity consumption stops and the oil retains heat for a long time. They are a reliable and economical source of heat and as there is no fan they are virtually silent, create no dust and don’t dry out the air. There are even mini, more energy efficient oil heaters available for smaller rooms.

Oil-Free radiator

Oil-free radiators use a unique oil-free, environmentally friendly heating technology to heat a room quicker and more efficiently than traditional oil-filled radiators. They have the same attributes as oil-filled radiators but are more heat effective, faster to warm up and tend to be lighter and easier to move.

Other Heater Types

Infra-Red heater

Infra-red heaters produce instant and directional hot air, providing fast heat. They are a safe and practical way to heat kitchens, bathrooms and work areas – anywhere were localized heating is required in fact.

Fan heater

Fan heaters are a great portable heating solution for workshops, garages, warehouses and office environments. They provide fast, directional heat and can be brought out when necessary and easily and safely stored for the rest of the time. Wall-mounted fan heaters are recommended for meeting halls and conference rooms, where heating is only required for relatively short periods of time.

Bathroom wall heater

Bathroom wall heaters have a compact, space-saving design, are quick and easy to install and provide fast warm-up with good air circulation.

Heated air curtain

Heated air curtains are the efficient way to keep heat inside and the cold out. They are ideal for doorways of shops, hotels, and offices.

Here at Lyco, we stock a full range of heaters to suit most requirements and are always at the end of the phone to answer any queries you may have.

Commercial lighting – the basics explained

Ivela High Bay Light - Translucent/Black

Every designer and electrician whose work brings them into contact with commercial lighting will be well aware of the vast range of suitable fittings and equipment available to them. They will also be conscious of the importance of choosing the right commercial lighting fittings for the project in hand. Similarly proprietors of businesses commissioning such work will have their own quite clear ideas as to what they need and expect from their new commercial lighting.

Lighting contractors will naturally have kept up to date with the exciting developments seen in recent times in lighting systems. Their customers may not however so it may be helpful to highlight some of the benefits they bring to users of commercial lighting.

Better lighting, better economy

Low energy lighting has been with us for some time now with its benefits of lower consumption of electricity and longer bulb life leading to improved economy in use. These benefits were achieved by the use of compact fluorescent bulbs but they were frequently criticised for being bulky, unattractive and producing light of lower intensity than expected. These lights still suit many situations but awareness of the other options that have become available more recently is essential if the right decisions are to be made.

With the advent of energy-saving halogen bulbs, metal halide lights and LED systems, light of greater brightness and intensity than was ever available from traditional incandescent bulbs and fluorescent tubes comes with dramatically improved economy. Every business needs to keep costs to a minimum and energy bills can account for a considerable proportion of overall operating costs. The high energy efficiency of these new forms of commercial lighting can bring about a significant improvement in the bottom line.

Examples

To show you exactly what we mean we have selected lighting examples from four broad categories of commercial lighting (retail display, high bay lighting, low bay lighting and including flush fittings) that suit all locations. We recommend suitable fittings for each situation.

Retail Display

The lighting here needs to clearly illuminate all areas of the sales area to enable customers to see everything clearly, move around safely and to deter thieves. The goods on display should be highlighted so that they are shown off to best advantage.

Metal halide lighting is perfect for this. Its bulb produces up to 115 lumens per Watt of electricity consumed compared to 35 for a traditional incandescent bulb. It lasts 20 times as long too, so economy comes as standard. These lights can light up a very large area or they can provide high intensity light on a small area.

A fine example is the Zeta Metal Halide Display Light from Robus in cast aluminium. You get a lovely crisp white light which really brings the display to life and showcases the products to best advantage.

Also ideal for situations such as shops are flush fitting. Flush mounted on either ceilings or walls they will illuminate large areas. These lamps use low energy bulbs for economy. For ultimate economy, LED versions are available.

High Bay Lighting

Here we are looking at lighting installed at heights of 20 feet (6 metres) or more above floor level, which may be in a warehouse, a sports hall, or maybe a large restaurant, even a pub or large retail sales area.

Recommended light fittings for these installations would include the 100w LED Linear High Bay Light. These high efficiency lights with their excellent economy are equally at home in High Bay situations where they are extremely effective.

Also extremely versatile and particularly suited to high bay installations are Solid Slim 200w LED Circular High Bay Lights. These are IP65 rated so they can be used where dry conditions cannot be guaranteed.

Low Bay Lighting

LowBayis required in situations where the lights are to be installed 3 to 7 metres or about 10 to 23 feet above floor level. Dextra’s Low Bay Lights – Metal Halide 250W are designed for just this purpose. These lights provide all the benefits of the latest metal halide technology as highlighted in the high bay lighting section plus a hinged gear tray which makes them quick and simple to both install and later maintain. The time thus saved represents a further saving in overall cost. Their robust construction makes them ideal for commercial lighting purposes particularly in factories, hangars, warehouses and loading bays.

Flush fittings like the Carina Flush Fitting LED White provide an excellent alternative in a low bay situation. The more limited the headroom available the greater the benefit of using flush fittings. We take a look at flush fitting lights next.

Flush Fitting Lights

Flush fitting lights are the maids-of-all-work of commercial lighting. We have two examples which show you just how versatile these lights are. Carina Flush Fitting LED White is the LED version of the Carina flush fitting mentioned under retail display. It provides all the advantages of flush fitting in that it protrudes very little from the surface it’s mounted on and can be wall mounted or ceiling. It is IP65 Rated which makes it ideal for hotel bathrooms, shower- cubicles and pub toilets or outdoors exposed to the elements.

On top of all that it is an LED light. LEDs produce beautiful white light, with the lowest of all energy consumption and the LED arrays outlast every other type of light source except the sun! Installing LED lighting is one of the few things a business can do which reduces costs whilst actually enhancing quality.

The other example is actually another version of the same light. The Carina LED Flush with Microwave Sensor – White. Here you get all the benefits already described plus the microwave sensor. The light can be mounted outdoors to light up walkways, steps or other areas either for safety or convenience. It can also be a security light.

Its microwave sensor detects movement and turns the light on only when needed. It can be adjusted to become active only when the ambient light falls below a pre-set level and its sensitivity can be varied between 1 and 10 metres so that it only detects movement in the relevant area. The time the light remains on when activated can be pre-set to between 10 seconds up to 30 minutes.

Indoors these are the ideal lights for rooms or passageways that are not in constant use. As someone enters the area the lights obligingly turn on. One extremely useful benefit of the microwave sensor when compared to the PIR type of movement detector is that the microwave sensor can see through doors! One advantage that gives is that when someone approaches a closed room the sensor inside the room detects their arrival outside the door and turns on the light ready for when they enter the room.

All LED lights cost very little to run. These only come on when needed and remain turned off and costing nothing the rest of the time.

Update to save

It’s not only new business premises or those undergoing extensive refurbishments that can benefit from these developments in commercial lighting. All businesses need to be alert to changes that can reduce trading costs and in many cases the cost of updating their lighting installations could be repaid many times over in the long term by the savings in running expenses.

Coloured bulbs – when to use them

Posted on 15th May 201329th July 2021 by Charles Barnett

Last updated on 29th July 2021

The coloured light bulb is hardly a new technology. Indeed many people might remember them from teenage years, as they are perfect for customising your room, being cheap, easy and quickly reversible, so they wouldn’t make your parents scream. While there is a lot more to coloured bulbs than simply popping in a purple one in so you can listen to Pink Floyd, there’s still an undeniable truth in there. Coloured light bulbs are a cheap and convenient way to completely change the look of a space.

Coloured bulbs for all purposes

The classic coloured GLS bulb is still available, in a wide range of colours, not to mention energy-saving and G9 halogen variants. But rather than blitzing the entire room with one colour, like an 80s nightclub, why not use the palette available to you creatively? For a peaceful sanctuary of a room, mix up green and blue bulbs, while a games room or bar would suit bright, vibrant reds and oranges. Interestingly, if you’re planning on a bit of poker, red lighting apparently encourages people to gamble more boldly.

Celebrations

Coloured bulbs are also great for seasonal celebrations – deck out a Valentine’s Day party (or a small girl’s bedroom) with pinks and reds, while greens and reds are great for truly festive feeling Christmas, and blue and green light will create a suitably monstrous Halloween.

Change the context

Don’t just limit yourself to using coloured light bulbs on their own. You can achieve amazing results when combining them with more traditional white lights, to add context and life to a room. This works particularly well when you’re trying to make a dull-looking room really pop. If you have a hallway, bathroom or other area that could best be described as ‘institutional’, replace the central lighting with coloured bulbs, and then use white spotlighting or table-lighting to create smaller, more intimate pools of light.

To break up long expanses of plain coloured wall, use splashes of colour to make the room interesting and break it up a bit, again using brighter spotlighting if you want to create smaller, more cosy feeling areas. At the other end of the scale, make a small room seem larger by shining coloured lights into every corner of the room.

Coloured spotlights

For subtle splashes of colour, spotlight bulbs, available both in halogen GU10 and LED GU10 types for standard spotlight fittings are perfect for adding a delicate flush to surroundings. Spotlights in particular are great for highlighting ornamental items, architectural features and art, as you can pick a shade that will really bring out the colours in whatever you’re illuminating. Best of all, spotlights can be recessed unobtrusively, so you can achieve some startling effects. Mount spotlights in narrow alcoves in an otherwise brightly lit room, for striking red or green features to break up the space. And if you can’t decide what colour you want, just get colour changing bulbs that change colour between red, green and blue.

Festoon finale

Finally, don’t forget those festoon lights. Yes, draping multi-coloured ones all the way round a garden or patio can make it look like a 70s holiday camp, but there are ways to use them strikingly. One of the most effective is to use just a single colour, such as all red or all white. This works particularly well with golf ball or pygmy bulbs, but is effective with coloured GLS bulbs too. Also, don’t just leave them outside.

Stringing up festoons around a living room or dining area can give it a bit of a festival bodega feeling, which works well if you have a basement living area. Don’t feel bound to string them up in the traditional fashion either – a great alternative is to wrap festoon lights around a pillar or beam, something best done with LED bulbs, as they hardly heat up.

If you’re looking for a different type why not take a look at our full range of coloured bulbs.

New build home lighting part 3 (Kitchen / Diner)

Posted on 7th May 201329th March 2022 by Charles Barnett

Last updated on 29th March 2022

A new build represents a blank canvas – a chance to set the tone for the whole house from the ground up. Your choice of lighting for new builds is a major part of what that tone will be, and is the filter that so much of the rest of the house will be viewed through.

So far our series on lighting for new builds has focused on the living room and hallway and then bedrooms and bathroom upstairs, Now we return downstairs to finish off the interior of our imaginary 2-bed starter home by stepping into the kitchen/dining room.

Choosing your lighting: the basics

Obviously one of the key factors in choosing lighting for any room will be the size and scale of the room itself. It might be the deciding factor, for example, in just how grand a chandelier centrepiece is in the dining room, or how extensive a set of cabinet downlights is in the kitchen.

However, that is a universal principle that applies in any room, and so doesn’t need special consideration here. Suffice to say, the larger and more attention-grabbing a lighting fixture is, the more space it needs around it – ignore that rule of thumb and you’ll overpower the room instead of illuminating it.

The same counts for brightness, although with the kitchen being typically one of the brightest rooms in the house you’ve got more room for error. That said, it’s a cardinal sin to under-illuminate a kitchen, so especially if you’re thinking of cabinet downlights make sure they’re close enough together and there’s enough of them (if there’s no other lighting in the room) to light up the entire kitchen.

New home kitchen / diner lighting ideas

There’s a wide range of kitchen / diner lighting products to choose from in the Lyco range. Here we highlight some of the most popular options available, and some of our personal favourites, to give you a sense of the choices available:

Retro style pendant: timeless class

Elstead Provence Rise and Fall Ceiling Pendant Light – Polished Nickel

This classic adjustable rise and fall pendant is the perfect multifunctional kitchen/diner light, bringing together old-world charm and class and contemporary styling complete with polished nickel finish.

Dimmable LEDs: high-tech kitchen lighting

View range here

Nothing gives a new build kitchen that ultra-modern look like LED spotlights, and the Fireguard LED7 range comes in various colour/warmth combinations so you can create just the right look for your kitchen. They’re available in fully dimmable form, and are IP65-rated and fire-rated for both commercial and domestic applications. Plus, the high-performance LEDs mean just 7W of power output matches of a 50W halogen for light output, but with an 80% energy saving.

Cabinet downlighting: low energy, little effort

View our range of cabinet lighting here

Cabinet downlights provide focused illumination on a specific area and are really simple to install, so it’s easy to see the appeal. In the case of the Aurora Mica LED Cabinet Light, you get the added advantage of a white light that’s rated for 50,000 hours and uses far less electricity than any standard light bulb. These LED lights can be surface mounted or recessed and come with 2m of cable included. You will however need an LED transformer, which is sold seperately.

Flexi striplighting: fun, decorative and versatile

View our range of cabinet strip lights

If you’re willing to put in a bit of effort and apply a bit of creativity, flexible striplighting is a clever and highly versatile way of lighting your kitchen – or any other room in the house, for that matter. Each 5M Flexi Strip incorporates 300 LEDs, and can be cut every 3 LEDs to suit just about any application. The strips are flexible and the LEDs come with a 120-degree beam angle, making it an ideal discreet lighting solution for shelves, alcoves, kick boards, cabinets… just about anywhere you can think to put them, in fact. We’ve chosen to highlight the “daylight” colour option here, but strips also come in warm white, and blue, as well as an RGB colour changing option.

If you’re connecting multiple strips together, or want your Flexi Strips to be dimmable, you’ll also need an Inline Amplifier. Last of all, a pack of Link Leads will come in handy should you wish to reconnect your cut LED strips.

The right lighting for new builds

New builds come in all shapes and sizes, which means specific lighting requirements for the kitchen/dining room area can vary greatly – and that’s not even accounting for the vast spectrum of personal taste.

The options we’ve shown here represent some of the more popular new build lighting options available, but of course you could also go for fluorescent or LED solid striplights, as well as halogen or other variations on the lighting types we’ve covered here.

Just remember that while room size might be the first thing you notice about any home, the right lighting to showcase that room is equally important, whether you’re looking to have a house valued for selling or renting, or are fitting a property out ahead of moving in yourself.

GU10 LED Bulbs – time to upgrade

Posted on 17th April 201329th July 2021 by Charles Barnett

Last updated on 29th July 2021

If you fit a lot of lighting, you’ll know the term ‘retrofit’. It refers to the new wave of bulbs that use the latest energy-saving technologies such as fluorescents and LEDs. They’re designed to look as much as possible like existing incandescent or halogen bulbs, perform as well as them (and ideally better) and most importantly fit into existing fittings, so you don’t have to replace anything in order to benefit from better bulb technology. That in itself wouldn’t be cost efficient.

Becoming popular

Retrofit bulbs for GLS fittings are already widespread, especially in energy-saving stick, spiral and GLS pendant variants, with LED GLS bulbs catching up fast. These of course have the advantage of a great deal of space to play with, as the large existing bulb shape offers enough room for the lighting elements and the circuitry that powers them. Plus they don’t even need to be standard bulb shaped, as GLS fittings are often quite open.

It’s not been quite so easy to directly replace GU10 halogen spotlight bulbs, however. A traditional GU10 is incredibly compact, thanks to the tiny but powerful halogen bulb inside. Because of this, GU10 fittings tend to be flush, especially to ceilings, with absolutely no space to cram in any extra bulk. Manufacturers have been working hard to find a solution to this, as there is a massive market for GU10 bulbs – think of all the fashionable bars, hotels, boardrooms and shops with a ceiling littered with flush spotlights – and they’ve started finding solutions.

LED is an investment

When you take a look at the listing for one of the newer GU10 LED bulbs, the first thing that you might notice is the price, especially if you’ve got a ceiling dotted with fittings you need to fill. So if these bulbs are multiple times the price of a basic halogen GU10, what are you getting for that cash? I hear you ask. Well…

Firstly, you’re getting a massive lifespan boost. The average GU10 LED bulb unit will last, depending on the model, between 25,000 to 40,000 hours. That’s up to twenty times longer than a halogen model!
As well as offering a massive long-term saving through longevity, an LED unit draws a fraction of the power drawn by the equivalent halogen bulb, so you’ll see your electricity bills plummet rapidly.
LED bulbs also give off a lot less heat than a halogen unit, so you’re less likely to see heat-damaged fittings, plus they can be used in situations where heat is an issue.</li

LED technology is improving fast

The sheer variety of LED GU10 bulbs has already eclipsed that of traditional bulbs. As well as current market-leaders in standard warm and cool white shades by Philips, Sylvania and GE, you can now get wide-angle and dimmable units for the first time. Or, if you have specific mood lighting effects in mind, you can not only get coloured bulbs but also ones that change colour according to a pre-programmed pattern. Surprisingly, these latter bulbs are far cheaper than standard LED GU10s, as they use a larger cluster of LEDs to provide the light.

LED GU10 bulbs have now even managed to achieve the same output levels as powerful halogen bulbs, with several 50-watt equivalents, and even a 65-watt equivalent on the market. This means there’s absolutely no reason not to replace power-hungry halogen bulbs with longer-lasting, cooler and cheaper-to-run LED units.

Take a look at our full range of GU10 LED bulbs.

Energy-Saving Light Bulbs – a definition

Posted on 21st March 201329th July 2021 by Charles Barnett

Last updated on 29th July 2021

The light bulb was invented by Thomas Alva Edison in 1879. Back then, the UK population was a significantly less than what it is today, there were no cars on the roads and no planes in the sky. Any overseas holiday was a cruise of sorts.

The world has changed hugely since 1879, and so has the technology that goes into light bulbs. However, traditional incandescent bulbs were only truly usurped as the go-to bulb by energy-saving light bulbs a handful of years ago. This was well overdue, as incandescent bulbs expend over 90 per cent of the energy they suck-up in outputting heat, rather than light.

In an increasingly energy- and environmentally-conscious world, those old bulbs have no real place – and are in the process of being forcefully phased out.

Rules of energy saving

Although there’s no hard and fast rule in terms of the exact savings required by these new light bulbs, compared to the old type, to define them as ‘energy saving’, the two most popular technologies use between 70 per cent and 85 per cent less. And as they last much longer, the savings will be felt in your pocket as well as by the environment.

CFL – the good, the bad & the ugly

The most common type of energy-saving light bulb is the CFL bulb, which stands for compact fluorescent lamp. Oddly enough, the first type of compact fluorescent lighting was developed not that long after the first incandescent bulb – back in 1890 but never made it into bulb form until 1976, some 84 years later.

However, it’s only in the last decade or so that they’ve gained real prominence on the high street. In 2007 when the UK government announced the UK phase-out of incandescent bulbs, the backlash against CFL bulbs said that they produced weak, ugly light that took an age to get up to full power. CFL bulbs were admirable in their aims, but not always so admirable in their performance.

Today, that’s simply not true. Most domestic bulbs are “instant on”, giving near-full power from the moment you flick the switch, and you can pick the colour temperature you’re after. Warm, or with a cool blue-ish tint – whatever you want.

There are many types of CFL bulbs out there. Perhaps the most familiar is the spiral. It’s cheap to buy and as there’s no extra layer beyond the fluorescent tube, its light output efficiency is excellent.

If you’re after something that has a look a little closer to the incandescent bulbs of old, we offer CFL bulbs that emulate both the traditional rounded bulb shape and the more elongated candle type. The latter is particularly strong as a decorative bulb – with a more elegant look than the slightly more efficient spiral shape.

CFL derivatives

There are CFLs that look almost nothing like light bulbs too. 2D bulbs unwind the fluorescent tube of other CFL bulbs to give even better light dispersal. They’re perfect for stair well, wall light or bulk head fittings, where function takes a lead over form.

Most CFL bulbs are designed to fit in exactly the same housings as old incandescent bulbs, but there are also pin-fit bulbs for fittings that incorporate everything but the bulb itself. The benefit of these bulbs is that they’re cheaper to produce – and hence cheaper to buy.

LED bulbs – not perfect but getting there

The other main type of energy saving lightbulb is CFL’s competitive and plucky younger brother – the LED bulb.

LEDs work in a completely different way to fluorescent bulbs, but offer comparable levels of energy efficiency. One of the key benefits of LED lights is that they do not contain Mercury, a poisonous substance found in CFL lights.

LED lights also solve one of the lingering problems of CFLs, whose lifespan drops significantly if they are turned on and off frequently. They also often offer better lifespan in general – LED lamps can last for up to 30,000 hours where some CFLs are only rated at 8,000 hours. However, this remains light years – or at least light days – ahead of incandescent bulbs.

The downsides of LED bulbs include that they’re generally significantly more expensive than the CFL type, and while they come in all sorts of shapes and sizes, they’re not always available in as high-power variants as CFL. For example, you won’t find a 60W-equivalent LED candle bulb… yet.

Halogen – a low energy alternative

There’s a third type of energy saving bulb too. CFL and LED are the kings of energy saving, but we can’t forget humble halogen. We offer energy saving halogen bulbs, which don’t contain harmful mercury and generally cost peanuts compared to CFL of LED bulbs. However, they remain much less energy-efficient.

The savings speak for themselves

Forgetting their life-spans for a minute, the clearest way to work out the energy efficiency of a bulb is to calculate its lumens per watt rating. A lumen is a standard unit of brightness. CFL and LED bulbs work out at around 50-70 lumens per watt. Halogen bulbs can manage around 20, while old incandescents will struggle to reach 15 lumens per watt.

Over the space of a year, the energy benefits of using CFL and LED lights is obvious – especially as they tend to last 5-10 times as long. Consumer body ‘Which’ has calculated that a single energy-efficient bulb will save you over £30 on your power bill over five years, and their calculation didn’t factor-in rising energy prices or inflation.

As incandescent bulbs continue to be phased out across the world, we’re only likely to see improvements in today’s energy-saving bulb technologies. What we should all be looking forward to is improvements in LED lights that’ll see prices of LED bulbs start to tumble. For now, why not check out our huge selection of energy saving LED bulbs?

High Frequency Lighting – what is it?

Posted on 26th February 201329th July 2021 by Charles Barnett

Last updated on 29th July 2021

Think of fluorescent lighting, especially in an office, and your first thought will probably be of harsh strip lighting, flickering slightly, and with a faint buzz that’s almost outside the range of hearing, but not far enough so that it doesn’t irritate. While that fluorescent buzz and flicker is great if you’re Michael Mann, and are looking for atmospheric urban effects for your latest film, they’re not so good if you have to live with them every day while you work.

Flicker no more!

You don’t need to put up with that flicker and buzz any more, as high frequency lighting produces strong, steady light that doesn’t visibly flicker, and eliminates hum and buzz completely within the human aural range.

High achievers

High frequency lighting achieves these results by doing exactly what it says on the box – increasing the frequency of the electric charge to the tube. Standard fluorescent lighting operates at a frequency of around 50-60Hz, while high frequency lighting boosts that to 30 KHz. As well as reducing flicker and hum, this also increases light output, and that’s not all. They also start up much more quickly, offering full light output within one second – no more hanging about waiting for the light to get bright enough to be able to do anything.

No added expense

You might think that all these benefits come at a much increased energy cost, but you’d be wrong. High frequency lighting actually improves energy efficiency by about 10%. They also maintain peak light output for longer than a standard fluorescent tube, and have a longer life-expectancy, so they more than cover the initial outlay involved in fitting them.

Less symptoms

There are potential benefits for the many people who find that they suffer from headaches and eyestrain if they spend a great deal of time under fluorescent lighting at work or school, particularly migraine sufferers. Published studies have shown that under high frequency lighting reported symptoms of headaches and eyestrain were more than halved, and that people were more likely to use the lighting when conditions required it. As well as making users happy, switching to high frequency lighting could also improve efficiency and reduce sick days.

Options

Since the introduction of LED, problem with flickering have become less and less common. When replacing standard switch-start fluorescent lighting, we would recommend strip lights and recessed light fittings in offices and corridors . Stylish external lighting can also be fitted thanks to brick lights, which look absolutely stunning alongside a swimming pool, garden path or in a car port, among many other uses.

There are a number of options if you want to fit lighting that won’t annoy users with noise and flicker, and will also save you money if continuous use is required. These include emergency recessed fittings, golf bulkhead fittings and low energy bulkhead fittings, which are ideal for stairwells and walkways.

Lighting controls explored

Posted on 15th February 20139th August 2024 by Charles Barnett

Last updated on 9th August 2024

The most basic form of lighting controls consist of simple on/off switches built into lamps themselves. That’s fine for such things as table lamps and work lights and in its most advanced form gives us the ability to switch the lamp on or off just by touching the base. The most developed types even provide brightness control.

Then there are the familiar wall-mounted switches, usually placed just inside the doorway controlling lights fixed in various places in a room. Again these can incorporate dimmers to control the level of brightness. For landings and staircases the switches can be two-way so that the light can be switched off or on at the top or at the bottom. For some situations, communal staircases in apartment blocks for example, timer switches provide the simple solution to human forgetfulness. The Electronic Time Delay Switch is a perfect example. When the light is switched on it remains on for long enough for anyone to ascend or descend the stairs and then is automatically switched off. The timing is adjustable to suit the situation.

Activated by changing levels of light is the Flush Mount Photocell Sensor controller. This clever piece of kit is capable of controlling as many different lights as you wish and can be overridden by the normal manual wall switch when required. The level of light is variable by adjustment too.

Another lighting control suitable for controlling multiple lights according to natural light levels is the Dusk To Dawn Photocell. Part of a range of dusk to dawn photo cell controllers, these can control outside security lighting as well as indoor lights.

The next level of sophistication in lighting controls works, not on light level but by detecting movement. If someone is moving about in the dark they must need a light, so the light obligingly switches on and stays on until a pre-determined time after all movement has ceased. This is all made possible by the Passive Infra Red detector, PIR for short.

PIR controllers come in many forms. Some such as the Timeguard 360° PIR Light Switch, can be used to control a number of separate lights from one location. The Light Switch with Movement Detector, is also used to replace the normal light switch and turns an ordinary lighting set-up into an automated system.

For a really unobtrusive PIR system of lighting controls there are small Flush Ceiling PIR Movement Switches. Several of these mounted at intervals of about 5 metres will ensure detection of movement everywhere in the room. These versatile units can be used with lamps of any kind and can even be used to control fans!

These controllers are ideal for use in rooms which are not occupied all the time, such as cloakrooms, so that lights are only on when actually needed. These lighting controls are not only a great convenience but over a year can save a great deal of expensive electricity.

The 360° PIR Light Controller is another one. Cunningly designed to detect movement over 360 degrees it doesn’t matter what the angle of approach, there is no blind spot. The length of time the light stays on when activated can be adjusted to suit the location making them ideal for corridors and staircases that are not in constant use.

Lighting controls then do rather more than take the effort out of flicking switches. They enable lights to come on when you enter a room with both hands full and similarly go out when you leave. Much better than trying to turn the lights off with your chin! They turn on lights when someone enters where they should not, alerting others to the incursion. Whilst performing these useful functions, lighting controls are also saving a fortune in electricity.

Wattage comparison – Goodbye Watts – Hello Lumens

Posted on 30th November 201229th July 2021 by Charles Barnett

Last updated on 29th July 2021

Not so very long ago, when incandescent bulbs ruled the roost, choosing the right light bulb based on brightness was incredibly simple, as it was all done in watts. And what’s a watt? Well it’s a measure of energy transfer (named after James Watt, the pioneer of steam engines), but that was always irrelevant. For years, everyone knew that 60 watts meant standard room lighting, 40 watts was a bit dingy, 100 watts was nice and bright for kitchens and bathrooms, and anything brighter than that was best left for surgeons and interrogators.

Getting rid of confusion

Everything’s changed now though, with the decline of incandescent bulbs and the rise of energy-saving and LED bulbs. All of a sudden, the wattage has changed drastically while the brightness has stayed the same, leading to a good deal of confusion. When energy-saving bulbs were first introduced, manufacturers initially dealt with this by printing the wattage the bulb was equivalent to on the packaging, e.g. ‘11w – 60w equivalent’. You can find a table of the more common equivalents at the bottom of the page, which is a reasonably good guide to the likely brightness level of your bulbs (not all energy-saving bulbs give off quite the same light, but then neither did incandescents). However this isn’t the whole story.

While it’s easy to make a rough comparison between incandescent and energy-saving bulbs, lighting is not just about these two types of bulb any more. There are also now various different types of LED bulb, not to mention halogen bulbs, and assorted tubes, so it’s virtually impossible to find a measure of energy that can be applied to all bulbs and still mean anything to the layman. Which is where lumens (lm) come in.

What is a lumen?

A lumen is a measure of the light given off by any light source that can be perceived by the human eye (i.e. not including the invisible wavelengths). Lumens basically cuts out any measurement of how much energy it takes to produce a given amount of light, and just measures the light given off. This is like your car’s speedometer measuring how fast you’re going, rather than the amount of energy it takes to get you to that speed, and is a far more sensible way of defining light levels.

You’ll need to get used to Lumens too, as EU legislation now states that the lumen value of a particular bulb must be printed most prominently on packaging. It’s not hard to see watts and equivalent wattages going the way of pounds, ounces and the dodo in the fullness of time. So how do lumens work then?

Rough equivalents

As a rule of thumb, lumens are very roughly equivalent to the incandescent wattage times ten, plus a little bit, so that a 450lm light source is roughly equivalent to an old 40 watt bulb, while an 800lm light source is similar to a 60 watt bulb. Comparisons for the most common sizes are in the table below.

Get ahead

Due to the huge variety of possible light levels available from new generation energy-saving and LED bulbs, it’s a good idea to get into the habit of thinking in lumens. It’s also a very good idea to buy spares when fitting multiple light sources in the same space, as wattage is now no longer a guarantee that a bulb will be the same level of brightness. Plus because bulbs lasts so much longer now, if one of your bulbs looks wrong, you won’t be stuck with it for months, but maybe for years!

Energy-saving bulb	Incandescent Bulb	Average Lumens
4-7 Watts	25 Watts	300
9-11 Watts	40 Watts	450
13-16 Watts	60 Watts	800
18-20 Watts	75 Watts	1100
22-25 Watts	100 Watts	1500
