If these are the older fluorescent lights, they typically have a "starter" and these do tend to fail, also the fluorescent tubes start to fail slowly, so you may not have a wiring problem as it may just be a tube or starter.
One word of caution, I have no experience with the new LED replacement tubes, but a couple of neighbors did have problems trying to do this. The other option is to just replace the entire fixture with a new LED type.

I seriously thought it was a typo. Thanks for the info. I love to learn something new everyday.

We have this in our new house on 3 circuits, all with led lights and dimmers. The lights can flicker when you initially turn the lights on. Have had galaxy out a few times and they made some adjustments internally in the dimmer switches and it still flickers only at startup, it has been cut down by quite a bit after they made these changes. I think the issue will be solved when I change out the bulbs

Make sure the new bulbs are labeled "DIMMABLE", you will pay a couple of dollars more but these are well worth it.

Yeah definitely not the tube (I mistakenly called it a bulb). We replaced it over a year ago when we noticed one day that it actually lit up. We didn't notice, for the past two years, that it did -not- light up. The lighting sort of wraps around the kitchen area in a U shape so it gets pretty bright in there even with the broken side. Then one day it was like "woah - it's so bright in here all of a sudden!" and that's when we realized we'd been living without 1/3 of our kitchen lighting for the past two years.

It still does that. Usually it doesn't illuminate. But once in awhile it will.

I have done a couple of conversions with LED replacement tubes, very simple and easy to do if you have done any simple wiring projects. .

Let me clarify, a couple of the neighbors tried these, and there was some compatibility problem, the LED lamps would NOT work in their fixtures. Per the instructions (as i recall) these were remove old and replace with new, no wiring changes.

Heh - the previous owner was big into DIY and screwed up a LOT of things that we had to fix. I'm afraid if we try tinkering with the wiring in the kitchen ceiling we'll end up with an expensive renovation job.

We started with bulbs how did tubes enter into the discussion?

In any case today with lower afternoon temp no flickering.

Because fluorescent lights flicker, and this is about kitchen lights, and I have kitchen lights, and some of them flicker. This is a thread about flickering kitchen lights.

Switch must be rated for led/incandescent.

Realized that lights are controlled by two switches. Will watch to see if flickering occurs on one outlet.

Is this happening on a new home? I needed to replace all the bulbs in both bathrooms since the bulbs were a low quality and began flickering after about 2-months. Change the bulbs and you'll be fine
