I have been noticing for quite a while that light bulbs in my apartment are burning out frequently, and I am now wondering if there is a larger problem. For example, the hood over my kitchen stove uses four small G4 halogen bulbs (2.2w=20w), and I am having to replace one of them every couple of weeks. That would imply an average lifespan for each bulb of about 8 weeks. With normal use of several hours a day, this would mean an average lifespan of about 100 hours of use. As I was replacing two bulbs last night (yes, two of them burned out the same day) I noticed that the package said the bulbs were rated for 2000 hours of use. That is a huge difference.
This is just an example, but I noticed that other bulbs in my apartment burn out frequently as well. And the bulbs in the building common areas seem to be burning out fairly frequently too. Is it possible there is an electrical problem in the building that is causing this? Fluctuation of current perhaps?
