I have a 4' VHO fixture that has been sitting in the garage for awhile (2009 while). It runs on a series circuit so i was thinking of going to Home Depot to buy cheap 48" bulbs to test the fixture to see if it still works. My question now is can i just pop in some normal output bulbs on the VHO fixture just to test it to make sure it still works, I don't know much about over driving bulbs so im hoping someone can chime in, they will only be on for a few seconds to a minute ( maybe i can return then afterwards :spin1: ). I plan to have 2 165W LED's with the 4 VHO's (if they still work) on my tank.
