I have about twelve 13 to 18 watt CFL Bulbs new in box. For awhile, my small electrical utility sold things like water heaters, light bulbs at give away prices. Buy one box of bulbs and get three boxes free. Beat the local Walmarts Anyway, they no longer sell things -- except electrical power -- and I have these "free bulbs." Was replacing one today and wondered if it was false economy to keep using the CFLs. They are new, decent quality and work as well as any of the CFLs do. A web search was inconclusive. With some saying replace, others say use them up and one source said if you only leave lights on for a shortwhile, it was more economical to toss all my new and used CFLs and replace with LED. On the other hand, leave lights on for long periods, use up the CFLs. Any thoughts? Yeah, sort of a so what question, but curiosity.... And, I must be old if this is how I spend Saturday night. But Spent a goodly part of the day playing frogger.
If you got them at firesale prices, tossing or keeping until spent is a wash (for you if not the environment). If you paid retail then I'd be behooved to use them, continuous-on or not.
