OK guys and gals I need some light bulb help. I'm running two shop lights on my big tank. they are both dual bulb 4' fixtures. And I need a bulb that is comparable to the ones that you would get with a standard aquarium strip light. the bulb that I pulled out of my other 4' strip light is a 32watt aquarium lamp. but it looks like a T6 and I need T8 or T12. So Can I run to the hardware store and pickup Aquarium bulbs?
