    The light in my ceiling will not turn off unless I turn off the circuit breaker. Is this a light fixture problem or electrical wiring problem?

  2. Dave Rongey says:

    Hi Doug,
    The light fixture is probably fine, however the switch that controls the light fixture should be tested and replaced if it is found faulty. That would be the first area of the electrical control circuit for the light fixture that I would begin to check.

    I have converted my 6 inch down lights to LED. The LED lights Flicker and have a strobe light effect only during certain times of the day. The lights are all brand new LED conversion kits and brand new dimmer switches. I recently added a new section of lights and roughly 20 of those Flicker twice as bad as the others only at a certain times around 4 or 5. I thought this may be the grid possibly?

  4. Dave Rongey says:

    Hi Todd,
    To help you troubleshoot the problem with your lights the voltage should be tested and verified, and the wiring connections should be checked for proper connections to the electrical circuit.
    Thank you for sharing your light fixture question,
