Welcome to the list.

If you're handy with tools and able to design & fabricate, building an
exposure unit is an easy weekend project. Construct a wooden box to hold
your bulbs and bulb sockets. 1"x6" boards with a thin plywood backing works
well. Position a large piece of sheet metal immediately behind the bulbs -
otherwise they won't turn on. Go to a electrical supply house to buy the
bulbs and associated hardware.

My homemade exposure unit has (8) Sylvania F20T12/350BL flourescent tubes in
it. Exposures range from 1.5 to 8 minutes for gum, and 5 to 15 minutes for
cyanotype.

Best regards,
