Adorama Glow-in-the-Dark Tape 1″X 5 Yards

A safe phosphorescent vinyl tape that gives off a soft green glow that will not damage your films or papers. Stick some on next to your light switch, darkroom timer, tanks, trays, etc. The self-adhesive peel off backing allows it to be applied to almost anything that seems to disappear when you look for it in the dark.
