Thanks for the suggestions.

I checked the voltage to the socket and it measures 125 Volts. I checked other outlets that work OK and the voltage is the same. I think the wiring is OK.

I’ll inspect the socket better too to see if it has corroded and is generating heat.

The light is enclosed in a probably 12” x 5” glass cover and air can’t circulate. It probably does get hotter in there than the rest of the house’s fixtures.

I do have a dimmer on the living room light and that one does last longer. I was thinking about putting a dimmer in the kitchen.

I’ll look up the other bulbs mentioned. I wish LED bulbs would come down a bit more in price.
