If you want to save significant money in your energy costs, target the vulnerable areas where power is being unnecessarily guzzled. Floodlighting is one of the strongholds of halogen because it intrinsically furnaces out a powerful beam of light, but boy is that type of light expensive to run! Anything that’s relatively cheap to buy up front has a catch. Think of inkjet printers and the cost of the actual ink!
Enter LED... It may not be the first technology you think of when you want to bathe a large area in light, and it costs more up-front, but the actual running costs are far lower! Consider that LED technology uses 80-90% less juice than incandescent. LED technology is well suited to rough and tumble forms of outdoor lighting, too, because by nature it’s resistant to vibration and shock -it can take a punch!
The thing about the straight flood light, the work light, the utility light, is that it’s always on. And if a 300W or 400W halogen light is always on that heat it produces is far-reaching - it’ll burn a whole right through your pocket! Pick halogen if your need for a floodlight is limited or occasional, then it makes sense. But if you’re going to be using a light on a regular basis, a wise initial investment in the right technology will quickly be returned.
LED just makes sense when you’re investing in a floodlight. It’s like that inkjet thing again - many people would spend more on a printer rather than be repeatedly stung afterwards with expensive inks. But they can’t as printers are usually cheap, inks are expensive. In some respects it’s a kind of cartel. With lighting however, you’re afforded the luxury of choice, thanks to the light-emitting diode.
