Will this bulb dim without flickering or making noise?

This 7W LED bulb dims down smoothly with traditional TRIAC dimmers. There is a faint buzzing sound, but I have to listen in closely (within 1 ft) to notice it.

I own five of them. They are in my kitchen. I have not noticed any flickering. Even when dimmed.

In short, No. That said, it depends on the LED light. Most dimmable LED's start to flicker when they get below 20% of full brightness. I have Switch Bulbs on a Maestro and they begin to flicker at about 15 to 20% of full brightness, it's dim but not to the level incandescent can get. I also have Phillips & Switch bulb (2 connected lamps) on a Diva dimmer and the Phillips flickers well before the Switch. Now I co have several Cree Recesses lights (Home Depot) on a Diva dimmers and they dim down right to candle light level. All the switches I use are designed for CFL & LED. The fact that the Cree recessed lights go all the way down to that barely on level I think has more to do with the lights LED electronics rather than the Maestro or Diva dimmer. I haven't used enough variety to be suitably knowledgeable in a definitive manner. Hope this helps.

I installed this using a LED lightbulb. It does dim but when you press the dimmer switch to turn off, it doesn't turn off completely. These same light bulbs are advertised as dimmable and work well with other dimmers (some specifically for LED light bulbs). However, this dimmer seems not to be completely compatible.

Mine work with any type of dimmer. No humming. I see that others have written reviews were they complain about buzzing. I haven't used one on a lamp next to a reading chair where I might notice a hum. I have them in ceiling cans with a dimmer switch. Never noticed a hum or any black spots on the bulb. I'm an mechanical engineer. Sorry, but LED bulbs don't hum when the voltage is reduced.

Not sure, either. The potential problem: the bulb uses such a low current that the dimmer does not "sense" enough current use to maintain accurate control, causing the lamp to flicker.

There is a low level buzzing sound from this bulb when you dim it, but it's nowhere near as annoying as flourescent tubes

I have this bulb outside, used for lighting the driveway and walkways (actually four of them). The don't buzz, but then I don't used them on a light that dims. BTW, I'm very happy with the light output. Hope this helps.

No leave the bulb alone. My bulb makes no noise when it turns off due to no motion nor at the switch.

I have not tried dimming. But I suspect that it would respond like regular tube fluorescent. My 200 watt CFL gives a blue-ish glow which took a bit to get used to. But it works fine.

I have had my lamp for one month now, and I have not heard any buzzing noises. Hope this helped, you might want to get a return.

Yes. It dims in the same style as the incandescent bulb. However, it dims more quickly...so the dimming effect is not as pronounced. But it definitely does NOT just abruptly shut off. We have had these in for a year+. No issues at all so far other than being very pleased with the brighter interior light. Makes Pilot look much more modern. We have Grey interior.

Yes, mine seems much dimmer and flickers..doesnt bother me, but i assume it was meant to be like this.

the lamp i put mine in wasnt a dimming lamp so i dont know FOR SURE.....but LEDs are tough and long lasting and I'd be very surprised if this bulb couldnt dimm when put in a fixture controlled with a proper Dimmer switch

Yes. In my application, I have this sensor controlling 5 LED fixtures, each fixture holds 3 - 6 LED bulbs. The voltage reducers are part of the fixtures. There is no hum or flickering.

Mine was dim from the get-go, so I didn't bother trying to get another one. Get a name brand bulb from someone reputable.

No. Not a sound. No odd flashing at any light level, or any of the other odd issues that sometimes happen with LED replacements.
