Anyone using this dimmer with the CREE brand LED bulbs such as the 60W ones? I am using a standard dimmer & get quite a but of buzzing that I dislike.

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'm using this dimmer and the Diva with the Cree LED bulbs and they all buzz. The buzzing is definitely a known issue with the Cree bulbs on basically any dimmer. I get buzzing on the full range, from dimmed all the way down to full power. If you check out reviews for the Cree bulbs (Amazon & home improvement stores) you'll see a lot comments about the buzzing with dimmers. Which is very disappointing since I like the Cree bulbs. For me the other positives of the Cree's out weigh the buzzing con.

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.

If they buzz, it is because they have a minimum amount of wattage that they need. Just because it turns on and you see light doesn't mean it is working properly. Increase the minimum level in the dimmer.

We have a bunch of these things running slightly more than 100 Cree LR6 modules and they work great as long as you can provide a load of at least 40-45 watts; anything less than that and the dimmer becomes unstable and you get noise and bad disco lighting effects (I'm pretty sure the modules don't like it, either).

They absolutely work with LED bulbs. You have to slide it all the way on and then adjust downward. With an 8watt LED bulb the I found the response to be very even all the way down. No buzz at the light or at the dimmer. Dimmer stays cool --but an 8 watt bulb isn't much.

I am having no problems with my led bulbs. I have been told that some of the less expensive dimmers don't work with led bulbs.

I cannot speak for LED's but I use dimmable CFL's in my fan. The remote does not operate like a typical dimmer with a high and low end. It oscillates from high to low as you hold down the on / off button. When I switched to the CFL's I found that they did not dim as low as when I was using regular incandescent bulbs. Now, when I want the lights to dim further, it bottoms out and begins to go brighter. I was able to get incandescent bulbs to dim more. Other than that, they work ok. The lack of dimming was not a big deal. I stayed with the CFL's since incandescent bulbs are being phased out. I cannot speak for LED's but I use dimmable CFL's in my fan.

With my LED set up which is 9 FEIT candelabra style 4w LED's, the bulbs flicker at lower dimming. Basically, they would flicker except at high or maximum. The LED's were rated for dimming.

I have only once tried to dim them using a Lutron dimmer that successfully dimmed six 50w halogen bulbs in a single fixture. This particular dimmer did not work with these LED bulbs. Perhaps another dimmer might but I don't have an installation to test them.

I have several LED type bulbs in my house, and the only ones I can get this to work with are the CREE Daylight White 40 watt equivalent (6 watt) the others I have are either not rated for DIMMER use or when in the "Off" setting the 60 watt or 100 watt version of the CREE bulbs stay on dimly.

Well, I am using 4 UltraLED 14W bulbs in one single fixture, and I am using the existing dimmer that I was using before whe I had 4 regular incandescent 60W bulbs. Seems to work fine, except that I can only dim the lights about 40%, after which the bulbs begin to flicker and the go off. Wish I could dim them more. Maybe I should be using a more compatible dimmer.

No buzzing, but with my dimmer switch you need to go to 50 % before they go on. They are wicked bright though (I have 4 on one switch). Also, once they are on, you can go below the 50%. Seems like there is a lot less control than with incandescent bulbs

I am using LED bulbs and am dimming them with the switch. So far, no problems and is working fine...make sure the bulbs state they are, in fact, dimmable.

Michael M. I don't know what you are doing but I have several of these and never have an issue. Granted they are not the best quality but no reason for dimmer not to work with them. Do make sure the LED bulbs are dimmable, if they are not you will get a strobe light effect.

You are not supposed to dim any CFLs that I know of. That's one advantage of LEDS. However, I have dimmed CFLs in the past, maybe I was just lucky but nothing happened other than they got dim. I try to avoid it though.

I believe you do. The same thing happened to me. I called the distributor of the bulbs and they confirmed that the dimmer model I was using was not compatible. I would recommend calling them to see if any dimmer is compatible, since the specs say they are NOT dimmable. Dimming was not critical for me, so I replaced the dimmer with a simple switch and have had no problems.

Make sure you are using a high-quality dimmer and one preferably tested and marketed to use with LED lighting. I have been able to dim my bulbs to about 50 percent. Below that, the light flickers or goes completely dark.

I have these throughout my home as well as tabletop dimmers. I don't hear buzzing from the dimmers themselves but from the dimmed lights, which is normal. The more you dim the more likely you are to hear a buzz from the light, especially if the full wattage is high and you have it dimmed low. This isn't harmful and in fact significantly lengthens the life of incandescent bulbs.

I use LUTRON C.L Dimmers. They work for all types of bulbs. If there is buzzing with these dimmer switches then there is a problem with the bulb and you should return it.

I don't have the Cree bulbs but a similar product. As long as any manufacturer LED bulb you install is dimmable, it should work.
