T5 humming

So I am sitting in my living room waiting on a big delivery and I hear a humming sound. I look around and I realize it's comming from my light fixture. I unplug it to see if that's really the problem and sure enough it is. I can use the moon lights but hen I turn on te bulbs I hear the humming. Is this a problem? Once I turn them on it takes about 30 sec for the humming to start

 

Could be a ballast. Is it fan cooled?

 

Re-seat the bulbs and see if that helps.

 

My Aquatic Life 6 bulb was just doing the same. I vacuumed out the fans on top and boom it was gone. Oh and how old are your bulbs

 

It doesn't have a fan and the bulbs were replaced about a month ago.

I have had it turned off for an hour and I turned them back on and so far so good no humming yet

 

Pay attention to it your ballast may be wearing out.

 

Ahhhh that's not good.... My wife will kill me if I buy a new fixture haha

 

You should be able to replace the ballast if necessary.
