That wouldn't be any fun. They don't contain any mercury.
LEDs bulbs are plentiful but expensive, I had six of the cheapest ones on the market but I had to return five of them.
I am one of the LED nuts and am really looking forward to the quality LED lightbulbs coming down in price.
The LEDs themselves continue to improve in brightness and color, my newer AAA key chain flashlight uses the Cree.
The Cree LED is brighter than the older ones but the life is only 50,000 hours instead of 100,000 hours.
But LEDs contain arsenic, gallium, and other toxics!
(In much smaller quantities than cfl’s but if you are truly green you must have something to complain about)
