Glow in the Dark photoluminescent Tapes

These"glow-in-the-dark" adhesive tapes are energized by a long-livedphoto-luminescent mineral (strontium oxide aluminate) that is non-toxic &non-radioactive  They charge fully with only 10 minutes exposure tolight. Any type of direct lighting will charge them.  Sunlight,halogen, xenon, full spectrum & fluorescent light work best.Glow lifespan is measured to the point of bare visibility to the darkness-adaptedeye, but may vary due to a) proximity to charging light source, b) angle ofexposure to source, and c) brightness of source lamp Photoluminescenttapes can be recharged virtually an infinite number of times and last 20 years with only a 2% diminishment in luminescence  Photoluminescent tape isused in areas such as egress and exit pathways, stairwells, evacuationcorridors, emergency exits, as long as they are lit well enough to charge the tape. Many municipal building codes now require photoluminescent markingson handrails in stairwells, across steps, and around exit doorways Photoluminescent tape can be used to mark instruments, switches, controls;anything important to see when the lights go out
