Couple hours ago i upgraded my lighting system. Bought a GLO T5HO Linear Flourescent Lighting System Bought a Power GLO bulb, pet store did not have the actinic bulb, so i am only running one bulb in it. The light keeps turning off after a few seconds, I asked pet store if it was because I only have one bulb in it they said probably not, and not sure what the problem is, and dont have a replacment, I'm wondering if it cause only one bulb?
