My version of Eprom eraser was a special flourescent tube in a standard batten. The eproms were placed in the tiny space between the tube and batten, a cardboard box placed over the top, then left on for a while. Can't remember how long it had to be irradiated (maybe 25 minutes? it's been too long ago)
One problem I noticed is if I programmed a Eprom then tried to erase it wouldn't work properly. Leaving the Eprom for a few days before erasure seemed to sort it out.
I still have the tube and batten, I suppose it might still work.
