I have tried both of them and they turn on fine but they go off the light CFL stays one and flickers LED stays on low.

Dimable CFL might work, or if at least one standard bulb is in the circuit it might also work

CFL bulbs can disrupt the signal over the wire. Try and replace the bulb with a standard bulb and see if it works. The new dim-able CFL bulbs tend to work, this is what I have now.

Just my 2 cents.. If you are getting this to save electricity and money.. buying a regular bulb or a more expensive dim-able compact florescent will set you back another year in making your money back on this light switch. Depending how often you forget to turn off your lights normally of course :)

Yes, we use CFL's in both of ours. We just have to click the switch twice, instead of once, to turn on the lamp. We really like the lamps.

I did a test with a household CFL twist and a BR40 CFL bulb, they both turned on off just fine.

It will work woith both CFL and LED ... Presently is turning on 5 23 watt CFL and 1 18 watt LED. It's been a great product and keeps setting with power outages.

the bulbs may flicker or not work at all with the old legacy dimmer. you should buy a dimmer made to work with the LED CFL bulb.

Well that is confusing! I have five of them and they all take the plain "old screw in" size bulb. Because they have a dimmer they will not work with the CFL. They would work with LED.

This dimmer is designed for incandescent / halogen lights. Also, CFLs are normally not dimmable, but even if you got dimmable CFLs or LEDs they may not work with this switch (of the two, LEDs are more likely to work, but they may also flicker, hum, and you may not get the full dimming range). Unfortunately, they don't have a model for dimmable CFLs or LEDs yet. Your best bet is to stick with incandescent / halogen lights on fans if you want them dimmable without any issues.

I would say yes, because LED's don't require the warm up time that the CFL's (swirl type) do. Because of the timer, the CFL's may not warm up to be fully lit in colder weather. Keep in mind, I'm not a light bulb specialist, but I'd give it a try. Because the LED's are expensive, keep your receipt for a return! :)

Yes it will work with both. However the cfl even if outdoor rated will take time to reach full brightness

I'm not sure about cfl but I know it doesn't turn off an led. Worst case you'll need to add a switch somewhere in the system to actually turn the light off

Yes. I have been running CFLs off three of these timers for more than a year. Works fine.

Through research, I found out they do not work with CFL or LED Bulbs. I ended up going with Maestro by Lutron MS-OPS2-WH and they work GREAT! Toughr.

I have energy saving cfl but the light blinks most if the time. Dimmer does not work well

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 have had problems with CFLs and LEDs in this lamp. They burn out quickly. I believe it has to do with the transformer in the power cord.

They both turn on simultaneously. If you want only the light you have to unplug the fan portion by removing the light bulb and unplugging the fan. I hope you don't mind noise because this unit is very noisy. Because of the noise I had to unplug the fan portion and just work with the main vent fan in the bathroom.

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.
