Recessed Lights Flash Off and On, Then Stay On


Hi, I recently installed new pot lights as part of a remodel. There are ten of them on three switches (4 on switch one, 4 on switch two, and 2 on the switch three). All of them seem to work fine, except that when I first turn them on, the 2 on switch three turn on with the switch, but then blink, for about 1 second, and then stay on with no problems. I am using flourescent lights in all of them except two, and I have rotated them to see if the bulbs are the problem, but it does this in the same two cans, whether I have incondescent or flourescent bulbs in them.

No idea what could be wrong, but I'd sure like to fix this before I finish the ceiling with sheetrock!

I appreciate any help.

Thanks,

Paul

Try two of the correctly working lamps in the fixtures that are giving you trouble to rule out bad lamps.

Possibly a loose connection or defective switch.

I've tried switching the bulbs, but with no success.

I was thinking of swapping out the switch to see if that has an effect. I'll give it a shot and let you know if that does it!

Are they IC rated cans? If they are, it is very possible the temperature switch is turning the lights off, on, then back off again.
Check inside the fixture for the sensor. Check to be certain no insulation is covering or surrounding the fixture. This causes excess heat and subsequent opening of the sensor inside the fixture.

The cans are IC rated, but I don't think it's a temp issue. It seems to have to do with having two dimmers on the same circuit. They are on different branches, in the same box. If I take one dimmer out (either one), and replace it with a non-dimmable switch, I have no problem with the lights turning off/on. I even tried switching the dimmers out with others, in case one was just bad, and that didn't resolve it.

Ahhhh HHHHHa...double check that the lamps are dimmable and the dimmer is rated for CFL use.

If it was so obvious that I should have known to include that I was using dimmers, why didn't you think to ask?

I was going to ask, but you specifically used the words switches.

If you are just going to talk down to the people on this forum by mocking them for doing the best they know how to do, I would rather not deal with you anyway. At the end of the day, you didn't help me at all...
