Hey all,

Have a problem with my 72" light hood. The hood that I bought has 3x 250 watt HQIs, and 8 T5 HOs. The issue is that one HQI bulb and 2 of the T5's have gone out. I switched out the ballast with one that I know works and the lamps still didn't light. My next troubleshooting attempt will be to take the light hood down, switch bulbs and see if that changes things.

Any other ideas?
