Colorine safelight paint by Rosco inc.

October 14, 2007, from Lloyd Erlick,

Some time ago I posted about a darkroom
material called Colorine bulb dipping paint,
made by Rosco, the company that makes gels
and color filters. It comes in many colors,
and is meant to paint light bulbs specific
colors.

The color I liked was number 27, safelight
red. I bought a little can, twenty bucks for
a half pint, and coated a number of small
light bulbs.

I've been very slow to actually test any of
these, and I've only placed them distant from
photosensitive materials so far.

Yesterday I did the simple 'CD darkroom
safelight test' on them. I held a CD under a
safelight, room lights off, and observed the
light reflected from the surface. There was a
definite blue component. Lights that have
proved safe reflect no blue light.

I realize the test is not definitive (in the
case of a light that seems safe and reflects
no blue) but as far as I am concerned these
lights are not safe and I'm not bothering
with painting light bulbs any more. It's
possible they need a second or third coat,
but I'm not sniffing that stuff any more just
to see if it works, and I'm sorry I brought
it up.

regards,
