Using LED Bulbs in Older Lamps

Compatibility, dimming and flicker.

LEDs draw far less current, which is good for old wiring, but cheap drivers buzz on leading-edge dimmers and 3-way LEDs need a genuine 3-way socket. Match the bulb to the socket, use dimmer-rated lamps, and check the base size before buying a case.

What we see on the bench

Nearly every lamp that comes through our Thornton shop tells the same story in a different way: the object outlived its wiring. Cord insulation dries out, socket contacts flatten, switch springs weaken, and the failure shows up as flicker long before it shows up as a dead lamp. Catching it at the flicker stage keeps a repair small.

When to call a professional

Stop using any lamp that smells hot, trips a breaker, or has visible copper. If the fixture is hardwired, mounted overhead, or older than 1960, have it inspected rather than patched. We give free estimates and will tell you when a repair is not worth the money.
