Very good article, if you are doing B&W only, great.

I worked in a commercial darkroom where there were 4' fluorescent lamps in some of the darkrooms but only tungsten in the rest.

The fluorescent tubes are a bit of a problem with colour paper as they do retain a slight afterglow. In a large darkroom this is sometimes not a problem, but in a smaller darkroom, there was a problem with long exposures with colour paper.

We were actually able to see the shape of the tube (glowing slightly) about 30 seconds after we turned the lights out, as our eyes started to open up.

Another issue was with the instant startup, they sort of fizzle a bit after repeated switching over a period of about a year. Especially if you are doing about 300 colour prints in a days work and there are two shifts.
