Forum newbie but not new to electrical stuff. I have a challenge I can't answer and am hoping to get some ideas.
I have two sinks in the master bath with wall mounted three-light fixtures above each sink. Never had a problem for years. About a year ago I replaced all 6 bulbs in these fixtures. The first day within hours of installing the bulbs one of them was broken: glass on the counter. I wrote it off as a fluke. Within two or three days three more exploded leaving glass on the counter. I figure the lot of bulbs were defective and returned the remaining 8 (out of box of 12).
I bought some new bulbs elsewhere, installed them, and got similar results. Tried yet another brand of bulbs and got the same result.
Here area few facts to add to the story:
- all the bulbs I tried are 130v bulbs. I prefer these because of the long life I typically get. I had some 130v spots in the kitchen that survived 10 years of daily use.
- for some reason, the center bulb in these three-light fixtures out-lasts the other two. I've gotten 4-6 weeks out of the center bulbs while the outside bulbs last a week at the most. Not years like the kitchen but better than the outside two.
- I tried A15 fan bulbs and flame-shaped bulbs in the process.
I thought I understood 110/220 wiring but this makes no sense to me. I would appreciate any thoughts.
