I bought a 5 pack of compact fluorescent bulbs from Sam’s. They cost more but last longer and use less energy, so they should be cheaper over time.
One burned out within 6 months in our storage room. Ted says they should not be put in places where you turn them on and off a lot. But that’s what we do with lights. Turn them on and off a lot.
I’ll call the 800# on the bulb and see what they say…
