Why do recessed lights go on and off?
Recessed canister lights are subject to some of the same problems found in ordinary ceiling light fixtures (see above). In addition, sometimes a recessed light fixture may mysteriously go on and of by itself. This is because recessed lights are equipped with limit switches designed to turn a fixture off automatically if the heat reaches an unsafe level. This can be for one of several reasons: 1 Check to see if the lightbulbs in the light fixture have the proper wattage for the light fixture. If the wattage is too high, it may be causing the fixture to overheat. Compare the wattage on the light bulb with the rating printed on the light fixture. Install a lower-wattage lightbulb, if necessary. 2 If insulation is packed too tightly around the light fixture, it may be trapping heat around the light fixture canister, causing the limit switch to overheat and shut down the light fixture. Make sure there is enough air circulation around the canister, which will prevent the fixture from overheating. 3 The limit switch may be faulty. If the light bulb wattage is correct and there seems to be proper ventilation around the light fixture, then consider replacing the limit switch or the entire light fixture.
