Buzzing noise from chandelier on new dimmer switch

Hello,

We have a chandelier that uses 5 standard lightbulbs (60W). I just istalled a dimmer switch and now there is a buzzing noise comming from the light fixture (I assume from the bulbs). The dimmer switch was rated for 600W, if that means anything here. The noise isn't horrible, just loud enough to bug me. It does get slightly louder the dimmer the lights are. Is this normal? Are there bulbs I can use that won't buzz?

Thanks.

What type of dimmer switch is it? Is it a $2 old fashioned resistance type where you push the round dial for on/off and turn for dimming, or is it a more modern electronic one?

Try a different brand and/or type of bulb.

It is a toggle switch with a slider bar along the side that is the dimmer. It cost $18 at a big box home improvement store.

I will try that. I am sure the bulbs in it now are cheapest around since the builder put them in when it was installed. I'll let you know if I find a brand that is at least quieter.

Yuo need a bulb with a thicker, more supported filament. Cheaper bulbs will "sing" on triac based dimmers (which most are) on lower brightnesses.

Follow up - Solution found

As Classicsat stated, the problem seems to be in the quality of bulbs:

Westinghouse contractor-supplied (read cheap) bulbs = loud buzzing

Phyllips Duralast bulbs = almost no buzzing

Thanks to everyone for their help.

ALMOST no buzzing is not good enough

Phillips - Halogena

Sylvania - Daylight Plus

GE - XL Ultra


Get yorself one of these and you will have no buzzing at all

thanks to Dim Bulb

Saw this thread and your answer -- bought the Halogena and they are SILENT! I thought I would just have to live with the buzz and I can't believe the change -- Thank you, thank you, thank you.
