** The CFLs on sale in the 1980s used iron ballasts and most had replaceable bulbs. When used as outdoor night lights on a premises, bulb lifespan is 1 to 2 years or about 8000 hours.


My newer CFLs, die like flies in comparison, particularly
in glass globe fittings.

** The last CFL I used as a night light lasted 4 years.

Naturally, it was cycled only once per day and that is the secret.
