Oh Great!! What next?? LED bulbs not as eco-friendly as some might think

LED light bulbs are becoming increasingly popular with designers and consumers of green technology, as they use less electricity, last longer, and emit more light on a pound-for-pound basis than traditional incandescent bulbs. However, while it may be tempting to look at them as having solved the problem of environmentally-unfriendly lighting, researchers from the University of California would advise against such thinking.

Scientists from UC Irvine and UC Davis pulverized multicolored LED Christmas lights, traffic signal lights, and automobile head and brake lights, allowed residue to leach from them, and then analyzed its chemical content. They discovered that low-intensity red LEDs contained up to eight times the amount of lead allowed under California law, although generally brighter bulbs tended to contain the most contaminants. While white bulbs had a lower lead content than their colored counterparts, they still had high levels of nickel.
