Anyone with DIY LED experience?

Yeah, LED's have a big up front cost, but... end up being cheaper than buying replacement bulbs, or close to the same. If you're thinking about the PAR lights that screw into the light bulbs, there's a guy who did a big tank with them on reef central. There's a new one now that has a good spread too, can't think of the name, they're usually known for being spotlightish, this one seems better.
