I have not yet tried it, but I am looking at various LED lighting solutions for my new basement shop. It is 12'x12' and I plan to install suspended ceiling, so I have been thinking about the 2'x4' LED light fixtures that they are offering from Cree. They seem to work very well, but the price tag seems a bit high. With a little luck the prices will start to come down a bit in the coming months before I need them. I think four of the 2x4 fixtures should do the trick in my shop, but I have a hunch I'll have to install some in the laundry room for my blushing bride as well.
