Thanks, I guess I was stunned with the output. This is just a 150HQI , This is a Sunsystem BluewaveIII , and it is only 150. However the bulbs I can't look at. The 250W halides mogul are bright, but don't seem as bright. I just thought perhaps the newer HQI were a boost up. I hear what you are saying about the 400. I have the 2 250W 13K on my 120 with 2 96 Power Compact for the actinic, and I love that. I just need really a 2 x 2 area lit for this application. I think I'll go with the HQI and see what happens. If I don't like the 14K I can always jot-back to the 2 halide system. It is just amazing how this pulls out the actinic spectrum
