Ceramic Bulb Making Popping Noise

I bought a new light bulb today and put it in.

Ceramic bulb making popping noise.

It is the original tile with no signs of repair or cracks in the tile or grout. The parts touch each other but might here and there be. My house was built in 1956. There is ceramic tile on the floor in the second floor bath.

The bulb consists of an assemblage of parts made from different materials metal glass plastic that have differing coefficients of thermal expansion. I am not completely sure of the method these bulbs use to rectify a low dc current for the led but theoretically even a switching supply shouldn t be making noise.

They usually will make a little pop as you turn them on or just after the don t keep popping.

It really shouldn t be making noise. It seems like i am always replacing light bulbs in this thing and they always seem to make a bit of a crackling noise and brighten and dim on their own frequently. It s actually the result of something called crazing which is a pottery defect that happens to new pottery that is under tension. One common pottery issue is you ll hear a pinging sound and you might wonder what that is.

Each of the 20 bulbs 5 per fitting emits this sound and they are in sync with each other at each fitting. Snapping hip syndrome sometimes called dancer s hip is a condition in which you hear a snapping sound or feel a snapping sensation in your hip when you walk run get up from a chair or swing. I have a ceiling fan with a light fixture in the extra bedroom i use as an office. This question would be better asked in electronics as i am sure at least one person there has pulled a bulb apart to see how it works.

It is the noise you make when you gently tap your finger on the top of a keyboard button. When i remove a bulb and place it next to my ear the ticking sound continues for about five seconds then slowly fades away to nothing.
