Durst Taucoli Cold Light Usage
What a great resource for analog photography! (this is my first post)
After a bit of searching past threads, I would like some advice from users of cold light heads generally, and particularly of the Durst Taucoli cold light (used on my Laborator 1000 4x5).
I realise that the head uses a flourescent tube and that it takes some five minutes (or more?) before the light output stabilises (checked this with an enlarging meter). I was originally getting inconsistent test strips depending (I think) on how long the enlarger is actually on.
My question is: Do you normally leave the enlarger head switched on during a darkroom session and cover the lens with a card until needing to expose paper and just use the timer unconnected to enlarger?
