Photoluminescent Tape - General Info:
These "glow-in-the-dark" adhesive tapes are energized by a long-lived photo-luminescent mineral (strontium oxide aluminate) that is non-toxic & non-radioactive. They charge fully with only 10 minutes exposure to light. 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-adapted eye, but may vary due to a) proximity to charging light source, b) angle of exposure to source, and c) brightness of source lamp. Photoluminescent tapes can be recharged virtually an infinite number of times and last 20 years with only a 2% diminishment in luminescence. They are used in areas such as egress and exit pathways, stairwells, evacuation corridors, emergency exits - as long as they are lit well enough to charge the tape. Many municipal building codes now require photoluminescent markings on handrails in stairwells, across steps, and around exit doorways.
"MOONGLOW" Photoluminescent Tape (below) has outstanding photoluminescence. It is the brightest photoluminecent tape we have ever seen, with a brightness after 10 minutes in darkness of 190 mcd/lux/sq.m. It lasts all night with a gradually diminishing glow. Moonglow recharges quickly (within 5 minutes) and has a glossy, easy to clean surface. It is flexible, very conformable, and is highly recommended for use on round hand rails in stairwells. It is excellent for types of emergency egress markings, exceeding NYC building Code RS6-1 and 6-1A. Moonglow is easy to write on with a permanent marker and makes great glow-in-the-dark labels and bands for anything you want to find in your tent in the darkness of night; flashlight, water bottle, bear spray, etc. It is also great on fishing lures, glowing brightly underwater.
Jessup Photoluminescent Tapes (below): For emergency egress and exit marking, Jessup 7550 24-hour Jessup 7730 10-hour photoluminescent tapes shown below meet requirements of ASTM E2072 and MIL-L-3891B for photoluminescent safety markings. Visibility to the night-adapted eye is up to 10 hours (7530 long-life ) or 24 hours (7550 ultra-premium). Jessup 7530 (see specs here) is suitable for most military and marine applications on flat surfaces. Jessup 7760 emergency egress tape is designed for use on round handrails in stairwells. It is thin, conformable, and pilfer proof (will fragment if removal is attempted). Note: it is important to consult your local building codes to determine exactly which tape may be required in your building.
