I hate to hear that...ImTooHIgh

Something is wrong with the ballast..I don't think the apartment juice would have anything to do with.

How long have you been using it?....first time?....how many watts?....what brand?....what brand of bulb?

There are SOME bulbs that are NOT compatible...with certain digital ballasts.

If the store gives you another like it.....I still wouldn't sleep well at night.
