I've done my research online about what causes bulbs to buzz when dimmed. It's the filament vibrating when the light is effectively turned on and off (effect of dimming).

Where can I find some 130v bulbs or bulbs with vibration resistant filament design? Any model names you guys use? What’s your experiences with this subject?

A much better solution is to use variable transformers as described here:

I am looking for a few bucks here, replacement bulbs kinda thing. Theater area is already built.

I had luck going from a GE 100 watt bulb to a Sylvania 40 watt bulb. I am guessing the filament is stronger and braced better. I need to see if I can at least go with a 75 watt bulb as I need more light.

I guess I'll try a sylvania 75 watt bulb and see what happens.

I'm not sure how you'd work that Staco variable transformer into the 'decor', unless you're shooting for the 50's industrial look.

Great option for a dedicated listening room or studio, where esthetics are low on the list, but the WAF is pretty high for the kitchen.

Are you sure it's the bulbs? I wired my kitchen with 4 inch low voltage lights and a dimmer, and cannot hear any sound whatsoever when dimmed. Or is this more prevalent with line voltage?

It's the bulbs.

I got rid of a buzz in my dining room by dropping from 100 watt bulbs to 40 watts.

It's the bulbs.

Are you sure? The reason I ask is because I'm in the planning stages of putting at least 12 recessed lights in my HT room. I was going to use 75 watt bulbs, as the wife wants to be able to read and wants a dual purpose room (and also wants better resale value). Putting 45 watt bulbs in isn't an option.

I could also go low voltage, which I'll consider if I have to do so, and it appears based on your posts that I may.

By the way, what type of bulbs are you using? I was thinking of using PAR 30 bulbs or PAR 38 bulbs.

I spoke to Lutron about this. Just get rough service bulbs. The filament is thicker and better supported and will not buzz. Worked for me. You do not need the ones with plastic coating glass, just the ones with a tougher filament.

Yes, it's bulbs. I put in 40 watt sylvanias and they did not make noise. I even tapped the bulbs with my fingers and the 40 watt sylvanias did not vibrate near as much as the 100 watt GEs.

I've heard of trying service bulbs (refrig/oven). It's all about getting a bulb that has a sturdy filament.

Due to the rapid heat/cool cycles in a dimmed bulb, cheap filaments will vibrate. 99 times out of 100, that's your problem.

Its your cheap bulbs. Replace them and the problem will go away.
