Anyone using LED based lighting for home (in place of 4Ft fluoro's)?

Once you have the LEDs in place, though, they will work nearly indefinitely. And since it takes so many to light a room you may never have to replace the whole array unless the transformer itself dies.
I light my shed with LED arrays. Two small fixtures of probably 30 super bright white LEDs, each runs off of either two or three AA batteries, and they do the whole 10x12 room. If you wanted to spend time in there you'd probably want to use four fixtures but two do make it safe to walk around in a room full of sharpened blades and tools.

How well do the LED units stand up to power spikes/surges? Probably not as good as fluorescents.

Doesn't that depend on the transformer being used on the array a lot more than the LEDs themselves? It's not like you plug LEDs right onto the 110v source.
richms:
The newer 3 and 5 watt LEDs are getting up to the efficiancy of T8 fluros, but they dont tell you about the transformer losses, which are quite high for LEDs at the moment, vs the ballasts for a large fluro which are getting down to 5% or so for a cheap electronic one.
Also the colour rendering of LEDs still leaves a lot to be desired - it can be done, but the efficiancy suffers. All up, they are a great replacement for spotlights at the moment, since led dies are about as close to a pointsource as your going to get, but for a replacement for a T5 or even an old T8 fluro, still not there yet.
