I have used a Phillips HPR 125 mercury vapour graphic arts lamp for years. It is
designed to peak at 365, 400, 435,546 and 578 nm which, in my experience, gives
good results across the range for alternative processes.
Being a single bulb, rather than a tube, designed to give an even spread of
light, the height can easily be adjusted to take account of larger prints, but,
of course, we have to take the inverse square law into account. The further away
the longer the exposure.
The cost is abouty eight to one hundred pounds.
