I'm just sort of thinking out loud and I'm completely useless when it comes to electrical work.
But I thought I would throw this idea out here to see if it's even possible.
I have a 36" aqualight pro with a 150w HQI MH and 2 x 65w pc's. Now the 2 pc's are only 22" in length.
Is it possible to replace the 22" pc's with 36" T5's? There is plenty of room in the hood for them to fit and the reflector goes all the way down. So if the coralife ballast can fire T5's it would be a significant lighting upgrade with minimal cost.
If this is possible, what wattage of T5's would work? And how many can I run?
