Feit light fixture LED flickers with dimmer: What to Check and What to Do Next
A Feit LED fixture that flickers on a dimmer most often has a compatibility or operating-range mismatch: the fixture may not be dimmable, the dimmer may not be rated for LED loads, the total load may be outside the dimmer's range, or the driver and dimmer may not work well together. Flicker that is strongest near the low end can sometimes be reduced by setting the dimmer's minimum level according to its instructions.

LED Light Flickers With a Dimmer: Check for a Non-Dimmable Lamp
If an LED light flickers when you move a dimmer, first check the lamp or fixture label for a clear dimmable marking. A non-dimmable LED is not intended to be controlled by a dimmer and can flicker or buzz; even a dimmable LED can flicker when its driver and dimmer are not a tested match, when the load is outside the control's range, or when the flicker appears only at the bottom of the dimming range.

Light fixture LED flickers with dimmer other switch may work: What to Check and What to Do Next
When an LED fixture flickers on a dimmer but appears normal from another switch, first determine whether the flicker happens only at the low or high end, throughout the range, during startup, or while the light is off. The usual next checks are whether the LED is marked dimmable, whether the dimmer and LED are a tested combination, and whether a multi-location circuit has the correct companion or mechanical control at the other location.

Light fixture LED flickers with dimmer: What to Check and What to Do Next
LED flicker that appears only with a dimmer is often a bulb, fixture-driver, dimmer, or load-compatibility issue, but flicker with heat, buzzing, arcing, burning odor, discoloration, or a tripping breaker needs an electrician. From the normal control position, observe where in the dimming range the flicker starts, read the bulb or fixture label without opening anything, compare another fixture, and record timing and heat or odor.

Lutron Light Fixture LED Flickers with Dimmer: What to Check and What to Do Next
A Lutron dimmer and LED fixture can flicker when the LED is not dimmable, the LED and dimmer are not on Lutron's compatibility list, or the light is being driven outside a stable part of its dimming range. First identify the exact Lutron dimmer and LED or fixture model, confirm the LED is dimmable, and note whether flicker occurs only near low or full brightness, only when off, or throughout the range.
