I use Cree brand LED bulbs for my 'normal' light bulb replacments and Sylvania spots for my in-ceiling can lights. I really don't like CFLs, especially the cheaper ones that take forever to fire. Not all CFLs are created equal and the bad ones are really crappy. As far as cost goes, you'll be hard pressed to see a really significant difference in utility savings. It will be cheaper, but OK electric costs aren't terrible, so the savings aren't massive. For instance, I replaced my 250w metal halide lights over my reef tank with 90w LED lights. These run 12hrs a day, every day. The 250w bulbs cost about $95/yr, the LEDs cost about $35/yr ton run (each). This difference is significant, but the real world impact on the wallet is not, especially considering the high cost of LEDs. For the fish tank lights, bulb replacement costs become a significant factor in the big picture ($50-100ea) since the LEDs probably won't need to be replaced in the lifetime of the tank. Lights for the house are much cheaper, so the comparison isn't exactly apples to apples. I decided to go with LEDs as my incandescents burn out because of the stupid laws limiting what can be produced now. I like 75w bulbs or brighter, and I can't get those at the store now. The LED options are really close and are getting affordable. My house also has issues with power surges killing my incandescent bulbs and LEDs hold up better. I do it for the intensity and because I don't have to run up the ladder as often.
Regarding cost, I've read stories from guys on the reef forums I read about their savings after an LED change over. Their KW/hr costs are high enough where real savings can be recognized and they can be pretty significant.
