A few days ago when I entered the garage I heard a noticeable 60 Hz buzz. Since this part of the house contains only fluorescent lighting I was a little confused at what it could be. The noise seemed to be coming from one of the incandescent bulbs on the ceiling; one which was giving off a strangely dim and off-color light. Switching the lights off then back on finished off the failing bulb, and it burned out in a typical flash.
I’m not completely sure what was occurring, but with quite a bit of darkening (likely condensed metal vapor) on the inside of the bulb and the odd colored light I strongly suspect that a gap had formed in the filament but was arcing, then on next power cycle the filament blew itself apart.
This bulb is one of two 300W incandescents that I use to illuminate the garage. I’ve considered putting in some bright, all-temperature fluorescent lighting, but doing that would be considerably more expensive than occasionally installing ceramic sockets and spending $5 every couple of years on a bulb.
That was the coolest looking lightbulb…. can you still buy them? Loved how clear the bulb was.
Mom: Yep! I got the replacements at Home Depot. Finding them is pretty easy.
