cfl's flickering

cappo11February 25, 2012

I have a 5 bulb bar light over my bathroom mirror. The light switch is a slide dimmer. I changed the incandescent bulbs out for dimmable cfl's but am finding that the lights flicker at the lower (dimmed) settings. also the bulbs are at different brightness. The cfl's are Feit brand 15 watt dimmables I bought at Home Depot. The dimmer is fine with incandescents. Was wondering what might be the problem

Thanks

Swap in a conventional switch to replace the dimmer. That is a sure cure.
Personally, the bath is the place where I do not want a dimmer.
If you really want this setup, try a different dimmer or experiment with different lamps.

You could try leaving the lamps on for about 100 hours and then see if they will dim down to a lower level without flickering.

If that doesn't work, try another brand of lamps. I only buy FEITs when I'm more concerned about price than quality.

CFLs are not going to dim like incandescent light, even if you have a 'dimmable' CFL or dimming ballast.

The difference in operation (discharge light vs. thermal heating) prevents any fluorescent from dimming as far.

since all the lamps in the store are inexpensive, do you think going online and buying a more expensive brand might solve the problem

A quick search for Feit 15 watt CFLs at HD brings up a product with a package that states "works on most dimmers."

Well, I guess there's their out - "most dimmers." You can try a dimmer that also indicates it's for dimmable CFLs or a different brand CFL.

Most OEM manufacturers now have just moved on to LED bulbs and really have no interest in improving their CFL designs.
