Does this dimmer work on CFL bulbs, is there any buzzing?

According to the listing at Home Depot, these switches are NOT CFL/LED compatible.

I have not tried on CFL's only in use on chandelier lights with 25-60W candelabra standard bulbs.

Sorry,I installed the 10 dimmers I bought on incandescent exterior/interior light fixtures. They work well on these lamps.

Dimming is done via the light switch and bulbs so be sure that whatever bulbs you choose to use can be dimmed. Not all CFL bulbs can be dimmed.

It may be the dimmer, I bought 6 for the economy of energy, one has already burned out, they do not buzz though

i didn't buzz when i used regular light bulbs or cfl. i did stop working completely after two weeks. second one that failed, just to warn you.

No it can't. the most it can dim is to about half brightness. At this level the buzzing incresed by a factor of 4. It gets really loud (the buzzing). I previously said the best choice would be to use those dimmable LEDs but with an old fashion (not special) dimmer. That seems to work the best.

This is not a good dimmer for CFL's at all. Its great for regulars, and halogens. I tried using it on all of the above. I'm actually looking for one that is rated for CFLs. Don't get me wrong, the dimmer itself is great for other bulbs. Just not the squiggly ones!

I know this is an old question but I just bought and installed this switch. I was worried (because of this question) about the switch buzzing. I have this hooked up to control 4 Cree 65W equivalent BR30 dimmable LED lights and notice no buzzing sound what so ever. Even at the lowest setting with my ear on the switch, I hear no buzzing.

Not that I've noticed. I have numerous LED bulbs, and none of them buzz. If they do I would send them back.

I didn't use this with Cree LED's specifically, I used Feit (Costco), and it works perfectly, no flicker or buzzing. This switch does have the ability to tweak the LED power consumption if you have any problems with flicker. Be aware that LED's don't get a low glow like incandescents so don't expect that. This switch does have a switch in it to go between incandescent and CFL/LED. Make sure you have it set to LED.

I can't hear any buzzing from my CFLs. But that might be just my hearing. I see that another answer talked about the lights failing quickly. While I have not had that problem another customer did. The bulbs come with a support phone number and are distributed by Home Depot.

Funny you should ask about CREE bulbs & this dimmer... I switched to the CREE bulbs and bought this dimmer as it's listed as compatible. HORRIBLE buzzing, I took the bulbs back to the big box retailer immediately. After much trouble shooting, including testing other bulbs... I realized the low load was the problem. 75w equivilant (13.5w) CREE LED bulbs got rid of the buzzing. FYI: my fixture requires 5 bulbs. I need a minimum of 60 watts total to keep the buzzing at bay in that fixture. I had the same issue in a 3 bulb fixture that needs a minimum of 40 watts.

I tried the dimmer with 2 ceiling lights with Cree soft white TW series. No buzzing, BUT when turning on the lights, they flicker once, and then don't always come on again. After flipping the switch a couple of times, they work correctly -- until they've been turned off for a few minutes. Then the probably occurs again, but only once. I've confirmed that incandescents work just fine, so it's not the electrical wiring.I have 60w Cree TW bulbs with an older Lutron dimmer that's designed for incandescents, and that combination doesn't have the same problem. The lights just don't fade in as well, because the older dimmer isn't designed to start with so little power, I guess. They fade out just fine though.

I just put the normal 60 Watt bulbs in mine. 3 levels of brightness and no buzzing noises on any of those levels.

The reason dimmers don't work with cfl bulbs is because they have to have a small ballast to power the bulb. You need to find a cfl that supports dimming. But you would probably be better off looking for a led bulb. You pay more up front but it will last much longer than even a cfl. Home Depot has a good selection of LED bulbs if you want to talk to a real person about it.

It also didn't work with an LED bulb I tried. All it did was Dim the bulb. The bulb I tried was not dimmable. Wondering if a Dimmable LED bulb would work. I tried 3 different brands of CFLs and one of them did work without flickering. The CFL bulb that worked was a 7 watt Greenlite which I received from my electric company.

these are 2800 lumens, equivalent to a 150watt incandescent bulb - the best feature is the white light output vs the yellowish light with standard incandescent bulbs. I do not notice any buzzing sound, but they are being used in ceiling fixtures of our church sanctuary. while it fits a medium base fixture, the bulb size is wide and long, so it might not fit in certain recessed or narrow fixtures

Yep, it's not a dimmer, just a timer, so CFL's are fine. As well as incandescents, water pumps, anything within it's current ratings.
