The photo-luminescent pigments in glow tape absorb and store energy from normal, ambient light. In sudden darkness, the tape is immediately visible. These tapes are a non-electric safety system that easily and inexpensively affixes to walls, handrails, columns, around door frames, and along stairways and baseboards. Glow Tape will glow in total darkness after exposure to artificial or natural light - it is fully charged within 30 minutes. Glows brightest the first 30 minutes after activation has ceased, but will remain clearly visible in a totally dark room to the night adapted eye.
