just look at incandescent lightbulbs...How many times have you seen them burn out at turn on as opposed to lighting the room for 20 minutes?
Right now for one of my room lights I have an incandescent that I'm using a variac on and the bulb is going on 3 years now. I always start it with 60vac and bring it up when needed. I have to do SOMETHING with the few that I still have
So then, slow turn on with an indirectly heated rectifier like a GZ34 will and does increase lifetime

- I agree with Sondek - full voltage at turn on will further reduce lifetime and - Story 07:28:07 07/21/23 (0)
