Brett, I am runnning 3 400 watt Radium metal halide with 4 80watt T-5 and 3 little led clusters for moon light. I purchased the fixture from Hamilton and it is called Cebu Sun. It was really inexpensive compared to my Pac Sun LED/T-5 Hybrid, I am extremely happy with the colors it has given me and I am ok with the heat, my chiller runs a little more but that it!
