I have a no name brand 6 bulb 24" ,24 watt T5 light. They work off a timer in conjunction with 2 Kessil A360's. Because, they are a "no name " brand, how hard can I drive these lights? I'm pretty sure they're not as bright as they could be. Can I use a 39watt ballast? More powerful? How does it work? What needs to be done? Thanks y'all!
