I am not sure what metal halide shimmer looks like but here are both.I thought I read that the halo grows red plants better, but maybe not tested? (hence the red tint). Also from your picture the halo shimmer's like a metal halide?
I agree, But the fan.. wonder if i can replace it with a more silent one.for me the versatility of the Halo will always trump the Kessil....
Sorry Buddy. I returned the Halo and kept the Kessils. The fans were too loud and the build just feels better with the Kessils.Do you have both lights at a similar intensity setting in this pic? If not, can you post a pic with both at or near maximum? I'm trying to choose between these two lights, but my tank is 30 inches deep so brighter is better.
