I had a yellow CFL in use as a porch light for centuries now. It finally died yesterday and I replaced it today. Strange looking thing - looks like a regular incandescent bulb but with the sides fallened instead of globular and you can see the coiled tube inside. No name on it. It's been running
24/7 for, I'll bet, about 10 or more years?. Only off when the power failed. First CFL I own that has died.Any CFL museums?
