Question: Are these bulbs compatible with dimmable light switches?
Document: Had this in a two-step light switch for about a week before it just died. Two-steps switches are those ones with a high and low option. It might have been the issue of the two-step switch but the packaging doesn't say anything about that being a problem. In fact, it says the bulb is dimmable.
I have been switching from CFL bulbs to LED throughout my house and these Cree bulbs are my choice. These bulbs provide a light that I find more comfortable than the CFL and work with dimmer switches. I am using them in lights that I had originally used with 90 watt incandescent bulbs without any particular problems. This six pack packaging is also easier to use than the two pack because it is much easier to remove the bulbs from the packaging.
The bulbs work extremely well, very bright and dimmable no problem. I will be purchasing more to continue switching out through my home.
Best led bulbs out there. One of the nicest things for me about these bulbs is that they are dimmable. I was finally able to replace my ceiling fan bulbs with ones that i could dim. The color and brightness are  superb. Besure to price check with your local stores.
Either way this is on a non-LED dimmer. On a dimmer that is compatible with LEDs it shouldn't be noticeable.
This was my first experiment with LED bulbs. And I thought that had done my research. I installed a new Lutron dimmer that was compatible LED bulbs. I even checked the Lutron website to make sure that this Cree bulb would work with the switch.
Not Cree bulbs. Cree bulbs work perfectly in all lamps and fixtures.They're virtually identical to an ordinary lightbulb, the color is warm and perfect. They last for years and years. They even work in dimmer switches! I can actually see a difference in my electric bill, and the bulbs are even Assembled in America.A no-brainer. Save money for doing nothing different. Highly recommended.
The great price isn't the only good thing about them. Comparable retail lights sell for a minimum of $10 or more apiece. Plus they are dimmable!
Using these in two ceiling fans (6-pack) and they work just fine. We do not use dimmer switches so cannot comment on that. But for the money these are great.
If you have ceiling-mounted fixtures that are covered with glass globes (sealed fixtures) and also use dimmer switches for those areas, THIS is the only LED bulb that works, and won't over heat or strobe-like flicker.So pleased after buying one, I bought the 6-pack. With a 10-year warranty, I don't expect to have to buy again anytime soon.
Answer: yes
