Curious about this. It ran you $400 or so. What does a comparable prebuilt run? No. Not baiting you. I simply haven't researched LED fixtures since right now my avatar takes all my spare $$$$$. That and I really have no clue what's available anymore.
Umm even I didnt research much on the commercially available units.
If yo talk about ray2, it would cost around $100. People have had good results with it.
But as you'll go in the advance world of LEDs, the prices will be $300 +. A unit like this, with sunset/ sunrise controller and 3 different series of lights, (1 white, 1 Royal Blue, and 1 for OCW), it'd definitely cost more than $500.
