There actually medium to medium high is you replace the colormax with a 6700k bulb. You need to remove the plastic cover over the lights. And use on a glass lid. I have it on my 55, and I was growing plants with nice shades of color to them. Greens reds pinks. I was able to carpet glosso easily, dhg, as well as a pot of hc.

It all depends on how far the light is to the substrate.
