Here is another thought...

Put in three systems:

1) Safelights;
2) Print evaluation and other special purpose incandescents; and
3) Spiral or other fluorescents for general cleanup etc - uses where you aren't needing to go back and forth between dark and light.

Have the switches for the safelights and incandescents in one location, and the fluorescent switch on another wall.

The fluorescents can be quite bright, without the attendant heat and high energy costs.
