Last fall, I switched my front and back porch lights from CFL to the Cree 60W-equivalent soft white LED bulbs. It was nice to have full light output on even the coldest winter days, and the light looks so much like an incandescent that it would be easy to think it really was (except for that little dark spot at the tip of the bulb). As a bonus, they use less electricity than even the CFLs (13W for the CFL, 9.5 for the LED).
Inside the house, though, I still have a bunch of CFLs to work through before I switch them over. I mainly wanted the full brightness at low temperatures for the outdoor lights.
