I have a very dark area around my enlargers. I don't like a lot of light falling on the easel when focusing and composing. When I'm using rather strong magenta filtration for those occasional soft negatives, I turn off all the safelights in the entire darkroom and focus in complete darkness except for the enlarger light.

However, since I have a rather simple "timer" (a footswitch for the enlarger light on/off and a metronome), my safelights stay on most of the time.
