I have a customer that lives in a large house with a rather large amount of recessed lights. The customer complained that her bulbs keep burning out about every 1.5 to 2 months. We've changed the bulbs on three occasions over the last 6 months.

We have inspected the metal contact tabs on a number of recessed lights and they seem fine. I've also changed her neutral bar since it was overloaded. Other then suggesting 130 volt bulbs are there any other areas we may be missing?

Any help would be greatly appreciated.
