  A BIG WARNING:

  Do  not use GERMICIDAL lamps. these have peak radiation in UV-C part
  of  the  spectrum (cca 270 nm). Photo resist, on the other hand, has
  the  peak sensitivity somwhere near 340-360nm (UV-A), so black light
  tubes would be OK.

  Shortwave  UV  (UV-C)  does not penetrate through the atmosphere and
  therefore is not present on the earth's surface and it is HARMFUL to
  eyes (causes irreversible damage to eyesight).
