What to check
Keep away from water
If water is dripping from a fixture, stay away, turn off the circuit from a dry spot and find the source of the leak.
Let it cool
Do not touch a hot fixture or bulb. Let it cool completely before anyone looks at it.
Water in a light fixture
Water dripping from a fixture means water is touching wiring. Switch off that circuit at the panel from a dry spot and keep away. If you see smoke, flames, or sparks that do not stop, leave the building and call 911.
Common fixture problems
Flickering
Flicker can come from a loose bulb, a failing socket, an incompatible dimmer or a loose connection in the box.
Fixture turns off by itself
Recessed lights have a thermal cutoff that shuts them off when they overheat, often from the wrong bulb or insulation against the fixture.
Buzzing or burning smell
Failing ballasts, LED drivers or overheated sockets buzz or smell. Turn it off and have it checked.
Water in the fixture
Water from a roof or plumbing leak above can reach the wiring. See ceiling water damage once the circuit is off.
What to have ready when you call
- Property ZIP code and whether it is a home, rental or business
- What kind of fixture: ceiling, recessed, outdoor, fluorescent or LED
- What happens: flicker, no power, heat, buzzing or water
- Whether it is on a dimmer
- Whether other lights on the circuit work
How light fixture repair usually works
- Turn off and test. The electrician shuts off the circuit and confirms it is dead.
- Diagnose. The bulb, socket, ballast or driver, wiring connections and switch are checked.
- Repair or replace. Failed parts are replaced, or the fixture is replaced if repair is not practical.
- Check the box. Overheated wires and loose connections in the box are corrected before the fixture goes back up.
Using bulbs above the fixture’s wattage rating overheats sockets and wiring. Check the label inside the fixture.

Call 833-877-1717Light fixture questions
Why does my LED light flicker?
Common causes are an incompatible dimmer, a loose bulb or connection, or a failing LED driver.
Why does my recessed light turn off and on?
Many recessed lights have a thermal cutoff. If the light cycles, it is overheating, often from a high-wattage bulb or insulation against a fixture not rated for it.
Is water in a light fixture dangerous?
Yes. Turn off the circuit from a dry spot, stay away from the fixture and stop the leak above it.
Can a fixture cause a fire?
Yes, if it overheats from wrong bulbs, damaged sockets or loose connections. A burning smell or discoloration means turn it off and have it checked.
Can I call at night?
Yes. You can call 833-877-1717 at any time, including nights, weekends and holidays. Whether an independent provider can come out right away depends on your ZIP code, the time and provider capacity, so availability is not guaranteed.
