  • Light which goes out???

    I have a room which the light works when the switch is turned on. Then after the light being on for 90 seconds to 1 hour, it suddenly turns off. What could be causing this? What are things that I should check for?

    Does this happen every time, or just now and then? If every time, you could have a time delay switch which needs to be replaced with a regular switch. Does it just go out or is there some flickering first?

      You didn't mention the type of fixture, but if the fixture is a recessed light using the wrong type bulb could be causing heat to trip the protection in the "can". ---Been there and done that!

        If it is a fluorescent light, could be the ballast dying...

          If it is an old incandescent, some times the tab up in the fixture, (the part that hits the button contact of the bulb), some times they get bent and the heat will pull them away from the bulb, and they will need to lightly pulled back out from the bottom of the socket, (SHUT OFF THE POWER) AND NOT JUST THE SWITCH, to make this adjustment.

          PUBLIC NOTICE: Due to recent budget cuts, the rising cost of electricity, gas, and oil...plus the current state of the economy............the light at the end of the tunnel, has been turned off.

            It's a regular bedroom light with two 60 watt bulbs. It happens almost everytime we turn on the light and leave it on for a period of time. Sometimes it will stay on an hour...sometimes only a couple minutes. Usually after turning it off for a while it will come back on which leads me to believe it has something to do with getting hot. Both bulbs go out at the same time...no flickering.

                If installing 2 new 60 Watt bulbs you still have the same problem, please try 40 Watt bulbs and post the results.

                  Pull the fixture and check the wire nut connections first. Could also be loose connection at the switch or a bad switch.
                  Make sure the power is off at the breaker and not just a coincidence that you turned off the breaker and the light went out on its own
