Given how fast mine have been crapping out, your “couple hundred” bulbs may last you 6 months. I had a conversation about this last evening. The woman was incensed that she cannot seem to keep bulbs in her appliances. I’ve replaced the bulb over my stove at least five times this year. Doesn’t seem to matter if they were made overseas or in the US.
I should have clarified: we bought normal light bulbs, not the stupid fluorescent tube things.
I suggest you check the voltage provided by your power company.
A few years ago my air conditioning unit went offline a few times due to an over voltage sensor. After checking and confirming an over voltage condition and unable to get a response from the local power company office, I wrote a letter to the state Public Service Commission.
Power Company responded within 1 week and determined they had a problem and eventually determined the problem was a voltage controller at a substation. The controller would raise the voltage if needed under a high load, but would not reset as the load decreased so the voltage would rise out of specifications.
I found out later that many people had to replace quite a few bulbs during this time.
