I know it is bad to put a fluorescent lamp in a dimmer socket. My question is will it shorten the life of a lamp to put a fluorescent bulb in a lamp with a 3 position switch? I suspect that it does because the one I have tried in a desk lamp's life seemed shorter. For the most part the lamp burned continually so I wasn't even using the switch.
I know the lamps are designed to put 120 on one filament for part of the switch and 120 on both parts in the other position but I am not sure what is happening when you turn on a fluorescent lamp.
