3 blue, 3 cool white, and 1 warm white. The smallest order is 5. I cant offered to order 5 at this time. BUT if i can find ppl that will be willing to purchase one from me i will buy 5 and sell 4.

I will sell each for $65 shipped. (price may change, but i will try to keep it as low as possible)

If you wish to have 4 blue and 3 white. or any other way let me know.

 

If any one thinks this wont work for a reef tank please let me know. I do not yet completely understand led's yet.
