I woke up this morning to an unlit closet. My ballast was making a humming noise but I could not get it to fire the hps bulb. I tried for an hour or so (with plenty of time between firings to let the bulb and ballast cool down) with no luck. I put my MH bulb in and it works. I have come to the conclusion it is the bulb is broken and I need a new one. I know that both Lowes and Home Depot sell a 400w HPS bulb (Lowes sells a Sylvania and HD sells a Phillips). My question is, which one is better? I need to go get this bulb TODAY! Quick responses are appreciated.
