Ikea lighting

[justinl]

I read about some of you guys using these Ikea LED lights on your tank (which was a really cool idea) and I was wondering if they would be enough to support any photosynthetic organisms (more specifically, xenia). Also, would you reccomend the white or blue colour? I don't have any, it's just a curiosity/just in case question.
