I wouldn't mess with LEDs that low power, not for a reef. Good off the shelf LED kits come with a high price tag, with good reason. What size tank is this for?

I just ordered all my supplies for a DIY LED kit. It's right under $500 so far but I will be running 108 3w LEDs powered by DIY drivers. This project will be mostly DIY, even the drivers. However, you could try the DIY kits at aquastyleonline.com; lots of people have reported success with them and they are very reasonably priced. The only caveat to them is you need to add heat sinks (which they also sell) and the drivers that come with them are only dimmable with a 0-10v analog signal, meaning you can't use an apex or most other store bought controllers to dim them, you must use a manual potentiometer. You could of course build your own controller that sends a 0-10v signal though.
