Need Ideas for LED supplemental lighting

[Slick Fork]

Depends on the colour he's after. I saw a reefbrite complete blue strip in action a few weeks ago and I've never seen a t5 provide that actinic pop. I'm definitely sold on the LED technology, it's the price I'm having a hard time with.

I'd check out the reefbrite strips, I'm considering retrofitting two of them into a 4 bulb tek light. They are probably the most "affordable" of the decent quality stuff out there right now, but I use that term loosely as they're still pretty spendy.
