Sandy,
I have successfully used a quartz halogen FEL 1000w lamp for gum printing. In fact, I prefer it over UV fluorescent tubes since I believe the latter cause fog and are less predictable in output than the FEL. The FEL lamp is standard in the Lowell DP photo studio light and can be purchased from a number of bulb suppliers as well as mail-order photo suppliers like Calumet. The cost is somewhere around $16 for the lamp.
iWhy do you state the quartz halogen lamps "would not work for your needs" in gum printing ?

Sarah,
There are many kind of quartz lamps, including halogen which would
not work for your needs. There is an Ultraviolet quart lamp that is
used in medical therapy. One place that handles this type of lamp is
Baar Products, at 1-610-873-4591. You can find other sources with a
Google search.
Be very sure that you understand the potential dangers in using a
lamp of this type. Most of the UV lamps that we use for exposing UV
processes (HID lamps such as mercury vapor and metal halide, BL, BLB,
and SA fluorescent tubes) put out most of their radiation in the
Ultraviolet A zone, which is not especially hazardous to your health.
I have not seen a spectral intensity chart for the medical therapy
lamps but if they put out a lot of UV in the range below 300
nanometers I would advise against their use.
There is an article on UV light sources for alternative processes
that you can see at http://unblinkingeye.com. However, I did not do
any research on UV quartz lights because at the time I did not know
that this type of lamp was being used to expose UV processes.
