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.

This makes it easier to keep track of small items in my tiny darkroom. However, be aware that this did fog my paper when I used the tape on my easel to see the edges better. But with normal usage ie not right next to my paper, it is working great. Its "charge" lasts much longer than the indicators on my enlarger timer.
I' m use this tape in my personal darkroom, slick it on light switch, door, etc. it help me more easy to find the switch, and door exit. easy to use, and great result.
