Bad news for all you LED users...

LED’s are no more safer or less toxic than CFL’s.... The more you know...
If you purchase daylight CFL’s, in the 5-6500K range, you arent left with that ugly yellow that alot of folks complain about. I use nothing but 6500k in the house and the lighting looks amazing.
And the likelihood of LED's "leaking" their toxic content, even in a landfill, is virtually zero (see above comment about multiple layers of encapsulation).
