Sorry for bringing this thread back but I am in a different situation now and was wondering if i can run 2 24" t5ho offa my icecap 430 without blowing up anything. The lableing says it will do it but i amworried that it may be too much wattage, or will the ballast know the difference? I really don't want to spend the money on bulbs if i going to blow em up, + i will have to build a canopy. I will be using them just for antec
