Hi! I recently pulled my small setup out of storage for 3 years. I went to test everything before ordering the clones and my 2 bulbs dont sparkle any more. is there a way to tell if it the bulb or something else like the ballast?
just buy another bulb, if it doesn't work then you know the ballast is probably busted and needs replacement and you got a spare bulb for when your current one burns out. there really isn't another other way then switching out a part.
