I don't think it's very amusez-vous trying to print cyanotype with a
"regular" fluorescent bulb, because it doesn't, though all else failing
you can expose dichromates (& I gather also pd/pl) with the *daylight*
fluorescent. These will I know print gum, though slower and
contrastier. I would assume however fluorescent bulbs for aquariums would
be available.... In states they average around 415 nm and are fine for
all "alt-photo" UV processes.
