In either case, replace; try to get a replacement from the manufacturer (since this should be within warranty for most LED bulbs, unless you used "inside-only" bulbs outside) but perhaps do that after buying a different brand to put where this one was, on the gamble that something different might work better there. LED bulbs can lose their brightness due to premature aging, bad internal components like a capacitor or LED arrays, or the common cause of loose wiring. However, just like any other electrical device, you are running into some issues with the technology that is supposed to last a long time. Very bizarre michael .

When the light switches are faulty, they can result in flickering lights. Telling folks to remove a safety device in a UL listed product is foolish and unsafe that's why I am down voting. Reviewed by Elyse Betters Picaro. This is done by a driver circuit that outputs a specific current, varying the voltage to hit that current. Since we need to do the repair task in the workshop, we will need brighter lights. A dimmer or RGB controller makes the pulses, with enough force to directly drive a considerable amount of LED light - like 130 watts (about 700 watts of incandescent).
