My electrician installed 5 LED lights in the kitchen, said that a dimmer is just fine. So be it.

All these flickering lights sounds like an episode of Stranger Things. Is there an upside down Villages?

The last item may require an electrician to check the wiring connection in the first light in the string of lights as i have seen intermittent operation that clears up when the connection heats up.
Does this happen all the time, at all times of the day? Are there any other electronic controls on these lights (Alexa, Apple,Ring, etc.)? Are all the lights the same, all LED or all incandescent?

Not all bulbs can be used with dimmers. Make sure you have the correct bulbs. I am also having this problem in a spare room but I will be calling an electrician if the bulb change does not correct the problem.

The Villages is upside down.

Where and what type dimmer switch did you get?

I had to change to LED bulbs in the kitchen overhead canister lights (since you cant get incandescent lights anymore). I then started having intermittent flickering once in a while only when opening refrigerator door or the oven or toaster oven cycles with the heating element.

I changed the dimmer switches to LED compatible ones which I obtained from ACE and Anixter supply house. I believe Lucent types and "LEV LED/CFL slides". ??
I also purchased expensive high quality LED no flicker Philips Ultra Definition Dimmable BR30 bulbs.

Guess what? Still get occasional flickering.

An electrician told me that LED's are highly sensitive to the electrical waves or fields or something like that which is why when an electrical appliance powers on or off it gives off interference...who knows?? I was also told that the new houses south of RT 44 have the same issues.

I guess I have to live with this not ready to market new LED technology>

Also how is it possible all four bulbs need replacement at one time?

Some LED bulbs are sensitive to temperature and are not rated for enclosed fixtures. I've also seen this before and if all the wiring and the dimmer is fine then it's the bulbs. The fact that its happening in the afternoon is because the attic is probably at it's hottest at that time of day.

Take a look at this graph about the heat index consecutive days and you might find your answer there. . especially since the event you are noticing coincides with very high energy demand from the entire grid. .

Last I heard were in a 7 years cooling trend

Hmm I see a chart but what am I missing?

high heat and high consecutive days of heat creates huge demand for cooling and power. Could validate your observation that the flickering is due to high heat and ergo power consumption near the limits of the supply provided.

If we are close to limit and they cut voltage thinking others would have noticed. Does seem to happen only when we are in the mid 90's.

If utility was close to limit would think they would ask people to voluntarily cut back on power usage.

They don't cut voltage, there is just so much usage that the voltage drops slightly and the LEDS are sensitive to that drop. Happens up here in MA occasionally and my UPS starts beeping. These are just the ups and downs of heavy usage when its very hot

Voluntary cut backs is when there are known issues. . .

Just back from a cruise to the north pole. (Well not quite but pretty close) and met an electrician who was very knowledgeable about our problem with the flickering lights in the late afternoon.

For those of you who said it was an LED bulb or two causing this give yourselves a pat on the back. Apparently it is the electronics in led bulbs.

Changed three bulbs and problem has gone away. Would have changed the other two but that was all the dimable bulbs we had.

Thank all for your suggestions.

Wow, replacing the bulbs worked. A contractor visit and four pages wasted.

Thanks for updating your thread with the solution. I wish everyone would remember to do the same.
