I have a couple light switches that are dimmers. In my guest bathroom, I have one connected to the 3-bulb light fixture above the mirror. I’ve made the mistake before of not getting dimmable bulbs, and make sure to clearly label all boxes of bulbs when I buy them so they don’t get mixed in with the other lights.
However, if I have the bathroom switch at any level of dim (i.e. not at 100%), the bulbs start flickering. I replaced them this morning with new bulbs from the same box, and they do the same thing. Apart from getting an incorrectly labeled box of bulbs, maybe I’m using too high of a wattage? They are 60W bulbs - would that have anything to do with it?
But, when you say “flickering,” do you mean a rhythmic flicker, or something random?
Because, if it’s random, you may have a loose connection, which could be dangerous.
I figured it out. The one bulb that wasn’t flickering turned out to be non-dimmable (I blame the in-laws for putting it in when they were trying to be helpful). Switching it out made the others stop flickering. Who knew?
I’ve tried probably 20 different “dimmable” LED bulbs, and I’ve never found one that dimmed as good as an incandescent, with some combination of lack of dimming range, horrible flickering, and premature failure. Since most of my house is on dimmers I finally gave up and wen back to halogen incandescents.
The ones I found that worked the best were the Philips “Warmglow” snowcone models. The first model of the filament warmglow weren’t as good and the current revision is worse
Not all dimmers are compatible with LEDs. I’m not an expert, but seem to recall reading that some dimmers cut off the leading edge of the sine wave while others cut off the trailing edge.
