I don't know squat about lighting. But I always heard LEDs were inferior to MH and T5's. Until I bought my Radion. Not only are my corals surviving, they are growing like crazy and it's set to cycle at 50% maximum intensity. I understand the need to have dim able lighting now. If I couldn't dim my lights, I would have killed em off in the first couple weeks of having the LEDs. Sounds to me like a trial and error thing. Might want to check into the PAR38 dimmable LED's that a lot of people are experimenting with. They have an aquarium version with a remote that control both the white or the blues according to ur preference. I might try it with my smaller tank. The PC on the bio cube ain't gettin it anymore. I'm tired of dealing with the heat issues when it is only putting out enough light to grow leathers. Waste of electric if u ask me

EL-BW21SL: Finnex 21 Daylight / Moonlight LED Aquarium Clip Light: Amazon.com: Pet Supplies

This one won't grow anything. Seems like a 24 hour light at moonlight levels
