It will take a while to get the purchase price down to a palatable level, but I'm sure the LED lights will beat CFL's actual (as opposed to touted) lifetime. I have four dead CFLs sitting on my workbench at home right now (I feel ripped off). One died seconds after installation. I'm looking forward to the LED lights just for the reliability.
I hope cost is good on these, LED's are going to be better than CFL's currently. CFL's have a fixed lifetime, and most are harsh looking. I've used some CFL's, but no more - unless it's somewhere I don't care about color. If cost is less or =$20/bulb, I can justify it.
I'm in! It's gotta be better than compact fluorescents: Those suckers are so shoddily-built that they often burn out in just a few months. That while they claim to "last [fill in any arbitrary marketing claim you'd like here] times longer than incandescent lights."
The average hours of use is probably a key metric as well. I would expect LED lights to have very good MTBF but there isn't any hint of that information here. This could suggest lower than expected lifetime.
