Question: Can this be used on lights attached to ceiling fans?
Document: I bought two of these. One runs a dinning room ceiling lamp with five 60w bulbs. No buzzing at all when used at the lowest setting or through the range. A bathroom light using six 60w bulbs buzzed terribly and I ended up removing the switch from controlling those lights (even with just 5, 4, 3, 2, and 1 bulb installed it still buzzed and different quality bulbs didn't help).
These are good altho somewhat overpriced for their function. They do not operate when using the energy saving bulbs, nor do they work on fans with lights at all!! We purchased these for this purpose and are tryin to find otherusable rooms for them now????? Maybe should have returned them for refund.
Bought this glider for our dining room chandelier. We don't dim the dining room lights a whole lot so wanted something that would be easy to go from full off to full on without much effort. Some family members had some initial complaints but after a while you get very used to just sliding the glider up to turn on the lights.
Lutron switches are routinely my fist choice for lights. Seldom any issues. The nice thing I've discovered is that these switches work fine with new LED lights that are marked as being dimmable.
Wired easily. Dimmer fits regular decorative plate. Two pieces for almond or white slider is nice. Comes with wire caps. Good price. Doesn't buzz. Only one quirk...you have to remember to push it hard enough to click to turn the lights off. My wife forgets and leaves the lights on minimum low instead of turning them off.
Easy to install and now can dim daughter's closet light to be a night light. I have used this product in the past with out issue
Very simple and cheap solution for dimmer switches, and I like the glide and the click at the bottom. We used to have the kind that look like regular switches but were dimmers, and they felt too 'floppy' in my hand. Can cause buzzing on some fixtures, so beware.
Used this in my bedroom with 4 recessed lamps, nice and easy install, about 5 minutes total, 4 star rating because the picture is deceiving, there is no cover plate included. Worked fine with my existing one tho.
Got this to replace another dimmer that used the standard toggle with a side slider, because everyone couldn't stand using it because the slider was so tiny. As we had a specific ornate plate for a 3-switch system, I had to find one that would fit a standard toggle plate.I looked around and saw one at Wal*Mart but they wanted over $11 for it.
including removing the face-plate and replacing it, it took me maybe.. 7 or 8 minutes at the most.Didn't need to snip any of the heatsinks to fit the switch which was good (Though, be aware, you'll lose 100watts for each side of the fins you remove)
Answer: yes
