kjamaya April 6, 2013 Share April 6, 2013 Got this annoying humming noise coming from my fixture when the whites come on. I normally have to smack it a couple of times in order for it to shut up. Anyone knows why? Link to comment Share on other sites More sharing options...
trockafella April 6, 2013 Share April 6, 2013 Possibly a fan.... What kind of fixture is it.? Where exactly does the noise sound like it comes from.? Link to comment Share on other sites More sharing options...

kjamaya April 6, 2013 Author Share April 6, 2013 72" current usa t5. Noise comes I believe from the middle of the fixture. Its def not the fan. Link to comment Share on other sites More sharing options...
kjamaya April 7, 2013 Author Share April 7, 2013 Wondering if I need to replace my ballast... will this stop the humming noise? Link to comment Share on other sites More sharing options...
flooddc April 7, 2013 Share April 7, 2013 Oh! check the light bulbs too. If it the ballasts it wouldn't be cost effective t replace it. Time for LED ! Link to comment Share on other sites More sharing options...
kjamaya April 7, 2013 Author Share April 7, 2013 Oh! check the light bulbs too. If it the ballasts it wouldn't be cost effective t replace it. Time for LED ! Bulbs are all new, as for ballast I have one brand new already and there are several people that sell them at great prices. I'm not sold yet on leds as I used to have them over my 75 and hated the disco ball look as well as my corals didn't do to well. But that's a whole other thread there. Just trying to figure out what the humming may be. Like I said it goes away whenever I hit the middle of my fixture... Link to comment Share on other sites More sharing options...
flooddc April 7, 2013 Share April 7, 2013 All ballast hums (harmonic), but newer electronic ones are pretty quiet. maybe loose ballast (since humming goes away). Try tighten the screw(s) before you replace it. Good luck Link to comment Share on other sites More sharing options...
Steve175 April 7, 2013 Share April 7, 2013 I too would take it down, open it, and tighten all the screws down: suspect something is loose. Link to comment Share on other sites More sharing options...

swimmatte April 8, 2013 Share April 8, 2013 The fact that it does away when you hit it really sounds like something is loose. Link to comment Share on other sites More sharing options...
treesprite April 8, 2013 Share April 8, 2013 My fixture was making a bunch of noise, so I put some foam under the legs and that stopped the problem completely. Link to comment Share on other sites More sharing options...
