What did I start? Here is HD's reviews
23-Watt (100W) Soft White CFL Light Bulbs (4-Pack) (E)*-ES5M8234 at The Home Depot I used one of these bulbs to replace another CFL that died. After 2-3 hours, the bulb started to flicker. Replaced it with a second one from the package. Same thing 2-3 hrs later. An incandestent bulb works fine.
Home Depot did make good on a refund and I bought another brand, same wattage. No problem after 12+ hours.
