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 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.
