..these names of these bulbs are rather confusing (and probably mean
different things in different countries). Anyway "black light tubes"i n
Holand mean these tubes they use (used..haven't been there
lately..;-)..) in disco's, which make your teeth and white Tshirt light
up. Anyway: these tubes have filters on it to block the more harmfull UV
light, precisly the frequencies we need, so your printing times will be
very long with these kind of tubes..

Best
