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).
