I have a 110V line in my kitchen with 4 LED lights and a toggle on-off switch (no dimmer.) The lights have steady power and everything behaves normally EXCEPT there is a one-time flicker of ~1/10 second about 3-5 minutes after turning the lights on.
- lights manually turned on
- steady power
- one-time simultaneous flicker after 3-5 minutes
- continued steady power
- lights manually turned off
- Rinse and repeat.
The power is good throughout the home, there's no brown-outs or otherwise bad power in this area (suburbs of a 1mil+ metro) and no other line from the breaker box performs this way. From the people I've talked to so far the best consensus I can come up with is to swap out the LED bulbs as they may be the culprit.
- How can I better troubleshoot this?
- If I change the bulbs what should I be aware of to ensure there won't be this seemingly 1-off flicker?
After recording the lights for minutes of time a few times it appears that the flicker happens continuously separate by stretches of time. Over time the flickers become shortened and less noticeable until they are undetectable by the human eye.
At this point I'm going to rule the issue to be temperature of the light bulb where colder temperature results in noticeable flickering. Especially now that we are in fall and temperatures have dropped this is more noticeable.
