I am considering a MH/T-5 fixture put out by Jalli. It is a 2x150watt 10000 K HQI with 2x39watt T-5 o3's. It has internal fans and is canopy or ceiling mountable.
I have a jalli 24 watt and a jalli 13 watt over my fuge part of the sump. They work fine but are made very cheaply! The 13 watt didn't work at first....turned out to be bad electronics. I bought it from a reputable dealer so he sent me another one and some free chaeto! Not sure if I would go with a MH system from them.
