Look at some of my instructables involving LEDs-
Make yourself Powerful LED Off-road lights/ headlights for your car!
Transform a boring old Table lamp into 2800 Lumen LED Blaster
There are quite a few advantages to using LEDs. Generally they are heatless, use 90% less energy, and last ten years. They are also smaller and do not contain any dangerous chemicals like mercury. They can readily be put in places that have always been too small or out-of-the-way for many incandescent lights, as well as in places that were always very dangerous or difficult to get at. Also, the more sophisticated LED apparatuses like wall washers and spotlights are DMX-controllable, which means they can be used in some really impressive ways.
The bottom line is that LED's are easier and safer to use than all previous lighting technologies. Plus, LEDs will save you money by consuming less power, lasting much longer, and generating much less heat, which in turn combine to result in lower climate control costs.
