My daughter just had extensive remodeling in her house. Both children's bedrooms now have cfl two bulb ceiling fixtures. Both fixtures, when switched on, start out with one bulb lit. After a few seconds the second bulb comes one for a few seconds and then goes off. This pattern continues while the fixture is on - one bulb constant, the other rhythmically cycling on. What might be causing this?

  • How hot are the lamp bases getting? What style of fixture are we talking about here? – ThreePhaseEel May 13 at 1:11

Continual cycling of fluorescent lamps on and off was once a symptom of a bad thermal starter switch or a dying fluorescent tube, but if your daughter's house was recently remodeled, it's very unlikely an ethical contractor would have installed such a lamp.

If this is truly a CFL (compact fluorescent lamp), designed to fit an incandescent lamp socket (Edison base, e.g. E26 in USA), just replace both lamps with modern LED lamps, which are more efficient, longer lasting and less expensive, and come in a variety of colors such as this "warm white" (2700 K) model.
