LED will be the bulb of the future. The US energy department has commited to that, but I think the drop dead date is 2015. By then the technology will have evolved, and the price will come down. Right now the cost of LED to replace a regular 40 watt bulb is $50 to $115, and the electrical savings would not pay that back if you lived to be a hundred!
So, I will stay with fluorescents until the government realizes they have created a mercury disaster that will make the Love Canal look like a tea party!
On the plus side, Home Depot has stepped up to the plate, and accepts all fluorescents for recycle from all comers. I do not go out of my way to recycle. Last weekend, my old microwave just went right in the dumpster, because I refuse to schlep that all over town. But HD stores are everywhere, and I AM a little concerned about mercury, so I will drop bulbs off there.
