treehugger.com is good too
LEDs are the holy grail of “green” lighting.
im working on a similar project, and ive learned that not only do LEDs have an exceptional life span, but the manufacturing process is actually relatively green (compared to lightbulbs and other plastics of similar sizes). in addition they use a ridiculously tiny amount of electricity for the amount and quality of light they produce.
thats all im going to say, we might be in competition some day
