Chandelier bulbs keep burning out or won't light

Chandeliers often use many small candelabra-base bulbs, and issues usually come down to a bulb-socket mismatch, a loose socket, or overloading a shared circuit within the fixture.

Symptoms

  • Some bulbs in the chandelier stay dark while others work
  • Bulbs burn out more often than expected
  • Whole chandelier flickers or dims unexpectedly

Likely causes

  • CommonA loose bulb in a candelabra-base socketSmaller candelabra bases can be easy to under-tighten.
  • CommonUsing bulbs with a higher wattage than the fixture is rated forChandeliers often have a strict per-bulb wattage limit listed on a label.
  • PossibleA failed socket within the fixtureIndividual sockets can fail while others on the same fixture keep working.
  • PossibleA dimmer not properly matched to the total LED wattageMany small LED bulbs together can fall below a dimmer's minimum load.

What to do

  1. Check and gently tighten each bulb, since candelabra bases loosen easily.
  2. Confirm bulb wattage matches the fixture's label, especially if using LED equivalents.
  3. Replace bulbs with a consistent, quality dimmable LED line if you have a mix of types.
  4. Turn off the breaker and check any consistently dark socket for corrosion or damage.
  5. Test a known-good bulb in the dark socket to isolate whether it's the bulb or the socket.
  6. Replace a failed individual socket if accessible, or the fixture if sockets are integrated and not serviceable.
  7. Have an electrician check the dimmer's compatibility if the whole chandelier flickers on a dimmer circuit.

When to call a pro

Call an electrician if a socket inside the fixture needs replacing and it's not a simple swap, or the dimmer needs upgrading.

Safety

Use caution

Turn off the breaker before inspecting individual sockets inside the fixture.
