And for others reading, just operate the lamp in a box, or in a spare
bathroom/photolab (I hang a warning sign on the door!). As has been
noted, it's dangerous to expose your eyes to the light, and no doubt
will also cause severe sunburns.

Gotta chirp in the middle here ;-]
I purchased a metal tool box, a germ light, and a electric timer a few years
back. I wired the whole thing up inside so that when close the lamp
is located just above the removable tray which has some contact foam
glued in place. I put the parts to be exposed/erased on the foam, close the lid
(which still has the padlock hasp on it if needed), plug it into the socket,
give the timer a twist and wait till it goes ding.
The lid seals well enough that no light escapes but a strip of door seal would
fix a toolbox with a poor fit. Other than the timer knob and the cord everything
fits inside the box and is protected. When done with it will easily stuff into a
closet. If you are doing stuff at home and have prying little fingers about aka
mutant rugrats aka kids you can put a lock on the hasp walk away from it
and not worry about them getting hurt or exposed.
I can't rem what the timer was from but it went to 45 or 60 minutes. Anyway this
has worked quite well for big and small batches for 11 years (getting old)
