I have 3 lighting systems in my DR, all incandescent.

One is bright for general work and uses 8 60W bulbs in overhead fixtures, the second is dim using 2 40 W bulbs for adaptation and work inbetween dark work and the third is 2 15W or 2 7W bulbs in beehive lamps used indirectly for dark work. I use yellow or red safelight for papers, depending on the paper, and I use total darkness for film.

I use the WR13 filter for color printing.

I have flashlights with WR70 filters on them for reading balances and graduate cylinders in the dark. They can be used with directed light for brief moments or can be pointed at my GraLab timer.

At Kodak, we had racks of these flashlights with different filters for different films and papers.
