I do just that, but I have made ND filters for the safelights, using heat/age damaged B&W paper, which has been developed, fixed, washed and dried. I use a 7-1/2 watt bulb in each fixture, and they hang about 30-inches above my sink.

I also have several 5x7 safelights, with the same home-made ND filters, and use a 4-watt bulb in each. The filters are pieces of old red lithographic masking film, taped to a piece of scrap 5x7 Plexiglas.
