Introducing Eutrac 3 circuit track lighting

The beauty of all track lighting lies in the ability to freely position lights without wiring constraints. This is useful for changeable applications such as galleries, exhibitions and retail displays. With most track lighting, any dimming or switching control has to be applied universally. All lights are run on a single circuit, so you dim them all at the same time and you switch them all on and off at the same time. So what is 3 circuit track lighting?

Triple your display lighting options

A 3 circuit track piece integrates three live copper conductors, running along its entire length. These conductors allow three lighting circuits to be individually switched or dimmed in the same installation. When you add a light fitting to the track or want to change its role, you assign it to one of the three circuits by means of a dial. This dynamic system allows unlimited fine-tuning of light, which is a great asset in any professional display environment. Click the infographic below to see how it can be used in a retail environment…

Take a look at how a retail environement can benefit from 3 Circuit Track Lighting

Lyco are now pleased to offer the Eutrac 3 circuit track lighting system to their customers. A wide variety of modular components are available for this system, all in a choice of white or silver-grey finish. These include:

Light heads

Take a closer look at the Bima 1 GU10 Spotlight HeadThe Bima 1 GU10 Spotlight Head takes either halogen or LED GU10 lamps and is especially notable for its versatile 340° rotation and 200° tilting adjustability. This fitting is suitable for smaller professional display spaces as well as hospitality or residential applications.Take a closer look at the Puri GU10 Spotlight Head
Similar to the Bima is the Puri GU10 Spotlight, which offers outstanding value for money. The 85° tilting adjustment is more restrictive than that of the Bima, however, which accounts for its lower price. The Bima and the Puri are both available in twin-headed versions.

For larger professional display environments or sizeable commercial or hospitality venues, the Euro Spot 35W Track Light Head provides an answer. Its relatively low maximum wattage is indicative of the energy efficient metal halide lamp it takes, which produces a phenomenal amount of bright white light. For exceptional colour rendering, a ceramic metal halide lamp is recommended.

Another powerful light head for the Eutrac system is the E27 Spot Track Head. As its name suggests, this takes regular E27 Edison Screw bulbs. PAR lamps are the light source of choice here, with a maximum wattage of 70W. Note that light output is likely to be less than the Euro Spot, but more than the GU10 fittings. Unlike the Euro Spot, the beam angle in this fitting is dictated by your choice of lamp output.

Take a closer look at the Forchini M Track Pendant

An unusual but useful option for the Eutrac system is the Forchini M 3 Circuit Track Pendant. This is great for providing ambient lighting and is especially useful where a relaxing mood is desirable. The gold interior of the pendant emphasises a warm output of light, which is ideal for hospitality or residential applications, or specific retail settings such as fashion or home furnishing shops.


Eutrac track pieces are available in 1m and 2m lengths, which can be cut to size for a bespoke lighting scheme. An expansive amount of track can be used, but the maximum load cannot exceed 3,840 watts.An example of 3 circuit track

The illustration below shows a piece of Eutrac triple-phase track. It includes an extruded aluminium profile and two PVC supporter profiles with embedded 2.5 mm2 cross section copper conductors. This design provides three independently switchable circuits with an earth connection through the aluminium profile.

Putting it all together

So far we’ve looked at triple-phase light heads and track pieces, but how is this 3 circuit system powered and pieced together? The Eutrac 3 Circuit Feed In delivers power to the track lighting system. Note that the position of the earth conductor must be aligned throughout the installation, so connecting pieces are all offered in a choice of left or right earth, or inside and outside in the case of angled connectors.

Take a closer look at the Eutrac 3 Circuit Feed InOur diverse selection of triple-phase track connectors allows any shape of installation you need. Included among them are straight connectors, cross- or X-shaped, flexible, T-shaped, and finally L-shaped for 90° corners. The connectors all have feed-in capability, allowing power supply at any junction.

The cheapest Eutrac component of all is the non-electric 3 Circuit End Cap, which gives a tidy finish to any linear track lighting installation.

Kits – easy openers

The Eutrac 3 circuit track lighting system is particularly useful for large display or task lighting installations, where a single circuit track installation may become unwieldy and cause compromise. Smaller track installations are achievable with convenient Eutrac 3 light kits, which still allow individual switching control over the included lights if required. The kits can be easily expanded using the aforementioned lights and accessories.

Uplighting: beam it up for extra effect

If you’re wondering exactly what “uplighting” refers to, your first guess is right. It’s a commonly used term for any lighting purposefully directed upwards. Light fittings specifically designed for this are predictably known as uplighters or uplights. But what’s the point of this lighting technique?

Creating drama

There are a couple of reasons for deliberately throwing light upward. Primarily, uplights are used to create drama. In this role, the light is positioned on the floor or ground and the light is directed up at an acute angle to glance off a wall, or a fence, or perhaps a statue or tree – this method is used indoors and out.

See our full range of floor uplightersOne thing sharply angled light does is emphasise texture; many objects that look flat in regular light take on a dramatic appearance under acute illumination, with their surface detail revealed. This technique also brings out form. A single light source or an asymmetrical pair of lights shone from beneath (and other angles) provides “modelling”, where light and shade outlines the shape of any item.

It is occasionally said that uplighting looks dramatic because our natural expectation is for light to come from above. A more established fact is that areas of light and dark create atmosphere. Because uplights are often set against subdued background lighting, or even darkness, they are always a fantastic choice for creating ambience.

Reflecting light

Another reason for pointing indoor or sheltered luminaires upward is to bounce light off upper wall areas and ceilings. This has the effect of widely dispersing a smooth light that is completely free of glare. Effectively it turns the ceiling into the light source, and a larger light source creates softer, more flattering illumination.

See our full range of Wall UplightersLight fittings used in this fashion might include floor lamps, concealed fluorescent fittings, and spotlights. The spread of light always depends to some extend on the nearness of the light source to the ceiling, its beam angle, and the light’s angle of incidence as it strikes the surface.

Indoor uplighting

Indoor uplighting works in either of the roles previously discussed. Lighting for drama nearly always means placing a light fitting on the floor. Light that is reflected off a ceiling is usually either wall-mounted or a freestanding lamp. Here are some examples:

The Limina Plaster Uplighter is an attractive luminaire for a hospitality setting or home. Set against subdued background lighting it dramatically lights architectural features, wall-mounted art, sculpture, or houseplants. As a cabled fitting, it serves as a floor or table lamp.

The Mother & Child Floor Lamp directs a phenomenal amount of light towards the ceiling using a powerful LED bulb, which is dimmable for fine-tuned effect. This type of luminaire provides a lot of coverage with its big throw of omnidirectional light, which is further dispersed by nearby surfaces.

A fitting such as the Spot 79 Spotlight might fulfil a similar role to the Opus. By mounting it on a wall and aiming its light upwards, the problem of glare is avoided and a wide spread of light is achieved. Spotlights are often overlooked for this purpose, but they provide good coverage for confined areas while taking up minimal space.

Outdoor uplighting

Most of us have probably noticed outdoor uplighting being used whilst on our travels, perhaps to dramatically illuminate a great cathedral at night. Architectural lighting is one way it is used, which will typically involve a powerful ground-fixed floodlight in outdoor situations.

The Edit Arris Wall Light is usable either as an outdoor uplight or downlight and is ideal for any modern premises. It is intended for decorative purposes, so how you install it falls to personal choice and may be influenced by existing lights or features.

Take a closer look at the Oslo LED Wall LightDrama is usually the motive when using uplighting outside. Popular targets for outdoor uplighting include trees and shrubs, statues, gazebos, fences, trellises, and garden walls. The same principle applies: uplighting gives these subjects texture and form and creates visual interest.

For shrubs, smaller trees, and many other garden items, the Garden Spotlights are ideal, they can be aimed directly upward to accentuate shape. A stronger alternative to Garden Spotlights is the High Power LED Ground Light, which are great option for lighting up large trees or an alternative to wall uplighters.

Water features such as fountains or ponds are often lit from beneath, or within, not least to avoid the peril of surface glare. Here, a product like the set of Garland SMD LED Walkover Lights works well. These provide decorative uplighting, and with their IP68 rating they can be immersed to a depth of 1 metre.

Become a lighting drama queen (or king)

We hope this article has provided you with ideas on how to create drama and mood with uplighting. It may have opened your eyes to how you can use existing surfaces to disperse light and avoid glare. Become a drama queen with your choice of lamps and light fittings!

Commercial & industrial lamps – pros & cons

Investment in lighting is important for any industrial or commercial premises. Practical benefits aside, the right choices will minimise running costs and strengthen profits. Linear fluorescent and HID (High Intensity Discharge) lights are the norm in this sector, though LED technology is gaining in popularity. This article looks at various commercial and industrial lamps and weighs up their pros and cons.

HID Lamps

HID lamps produce light by creating an electric arc between two electrodes in a gas-filled tube. They are a particularly powerful light source, used for car parks, gyms, factories, football stadiums, paths, roads, and warehouses. There are various types of HID lamp, as follows.

Metal Halide lamps last from 7,500 to 20,000 hours and are used in sports stadiums and car parks. They are also a good choice for warehouses and other high bay indoor purposes. The lamps produce a crisp white light and offer a good standard of colour rendering with typical CRI 60 to 70 scores. A choice of colour temperatures is possible, from warm white to daylight. With a luminous efficacy of between 80 and 120 lumens per watt, these lamps match the best LED or fluorescent products for energy efficiency.

Venture 250W Double Ended Metal Halide Bulb

A typical example of a metal halide lamp is the Venture 150W Double Ended Metal Halide, which has a cool 4200K colour temperature that’s ideal for work areas and sports activities.

The main disadvantages of metal halide lamps include light pollution, UV emission if their outer glass breaks, and use of mercury and other heavy metals.

Ceramic Metal Halide (CMH) lamps are also called ceramic discharge metal-halide lamps (CDM). The main difference between them and regular quartz metal halide lamps is that they allow a higher arc tube temperature, resulting in improved colour rendering and stability. For this reason, CDM lamps are often used in colour-critical applications such as retail display lighting, architectural lighting, or film and television.

The natural deluxe version of the G.E. 70W Single-Ended Ceramic Metal Halide boasts a CRI 90 score, which puts it ahead of most current LED products in terms of colour.

SON-E lamps are elliptically shaped, high-pressure sodium lamps. They are used in street lighting and general floodlighting. One of the main advantages of these lamps is their energy efficiency, which is shown by a luminous efficacy ranging from 65 to 140 lumens per watt. The higher end of that scale is unsurpassed by most light sources. Lifespan is also impressive with average expectancy of 15,000 to 50,000 hours. Colour temperature in these lamps is always warm.

SON lamps work with ignitors, which are either in the lamp itself (internal) or in the fitting (external). The 70w SON-E uses an internal ignitor and boasts a 12,000-hour lifespan and luminosity of 5,800 lumens.400W Son-E Bulb with Giant Screw Cap Fitting


On the down-side SON lamps offer poor colour rendering. A CRI 20 to CRI 30 score reflects this, which is unusable in any setting where colour recognition is important.

SON-T lamps are tubular high-pressure sodium lamps, with the same advantages and disadvantages as SON-E varieties (above).

White-Lux SON lamps are a metal halide lamp designed to work in a standard SON fitting. The main benefit is a more natural light with a cooler colour temperature and greatly improved colour rendering. Possible uses for this lamp are identical to those listed under metal halide, including sports stadiums and halls, car parks, and warehouses. This is a fine choice for anyone who wants to upgrade light quality in an existing SON fitting without having to change either the fitting or ballast.

Mercury vapour lamps are used in applications such as warehouses, car parks, stadia and other large-scale industrial buildings. They are a type of gas discharge lamp that uses an electric arc through vaporised mercury to emit light. A white phosphor coating is often used on the outer lamp to generate an intense white light.

The main drawbacks of high-pressure mercury vapour lamps are their slow 4-7 minute warm-up time, middling energy efficiency (about 50 lumens per watt), and inferior colour rendering compared to metal halide lamps.

Dual SON & Mercury lamps are dual metal halide lamps that can be used in either SON or mercury fittings for superior performance. They give a whiter, crisper light with improved colour rendering, and this is achievable without the cost of installing new light fittings or control gear. Suitable applications include factories, retail environments and sports halls.

White SON [SDW-T] lamps run at a higher pressure and temperature than regular SON lamps to achieve a superior standard of colour rendering. Manufactured by Philips, they usually carry a minimum CRI 80 score, which extends their suitability to applications such as downlighting, display lighting, and café or restaurant lighting.

There are disadvantages with White SON lamps, however, including high upfront cost and reduced energy efficiency. Our Philips models have a luminous efficacy of about 50 lumens per watt, which is less than half that of some HID lamps and is roughly equal to low-end LED or fluorescent lighting.

Philips 18W SOX lamp with a bayonet cap fitting

SOX (low-pressure sodium) lamps are gas discharge lamps that use sodium and neon gas to produce yellow light. These are the most energy-efficient of all artificial light sources, with typical luminous efficacies of between 100 and 180 lumens per watt. They are ideal for applications such as airports, harbours, foundries, orientation lighting, quarries, railway marshalling yards and crossings, rolling mills, security, and street lighting.

The main downside of a SOX lamp is its monochromatic light, which makes it impossible to discern colour in the absence of any other light source. For that reason, it’s a poor choice of lamp in any setting with colour safety markings or where crime prevention is needed.


The LED Light Panel is one of our most popular dedicated commercial LED light fittings

LED commercial and industrial lighting often comes in the form of dedicated LED fittings, which are so long-lived that they do not take replacement bulbs. The whole fitting is replaced at the end of its useful life. LED lighting is naturally directional and thus easy to control. For that reason, dedicated LED fittings are uncommonly efficient in delivering light and less wasteful than other sources.

Disadvantages of LED include greater upfront cost and lower energy efficiency at source than some rival products (the best LED lighting cannot match the lumens per watt performance of sodium lamps). On average, colour rendering is likely to be better in a ceramic metal halide lamp; most LED products have an approximate CRI 80 score.

Linear Fluorescent Lamps

Fluorescent tubes have long been popular in industrial and commercial environments as a cheap source of diffuse light. Lyco stocks a variety of fluorescent batten fittings to house them, some of which are usable outdoors. The main disadvantage of fluorescent lamps against HID lamps is that they produce less light, so you’ll theoretically need more fittings to provide the same coverage. They are also adversely affected by hot or cold temperatures, resulting in lower light levels. Linear fluorescent lighting is ideal for corridors, tunnels, and aisles.
