help. For the past 3 months my recessed kitchen light has worked fine. Controlled by standard switch. Not a dimmer and not a 3-way switch. Today I turn on and started blinking on and off about 1 sec each. Not related to any other appliances coming on and off. No changes to house electrical recently. There is no insulation around the light either. The light fixture/unit cost about $70 from home depot. It screwed into the old can light socket for easy install.

I left it off a few days and even removed and tested on anther circuit but same blinking problem. Took back to HD given replacement...defective device. Thanks for your suggestions however.

It's toasty up there...

This sounds like the classic behavior of a recessed fixture that is overheating and thus cycling on its thermal limiter. Try replacing the bulb with a smaller one, or one that has better heatsinking (doesn't get as hot).

  • Yes, the problem may cure itself this winter. Try also at 7am when the house is at its coolest. Aug 22 '18 at 23:09

I have been installing led retrofits in office fixtures for several years , I find 2 failures at this time the light starts flashing or will not light at all in both cases the driver has failed in every one of the fixtures that I tore apart and examined. I have lost or had failures at about 10% of the medium priced lamps / fixtures with 3-5 year warranties and less than 1% of high priced fixtures. I have found that most all the drivers are made in Taiwan or China and the only way to get longer lasting fixtures is to look for DLC listing and a longer warranty.
