Nightshine Pro light sticks are a new generation strontium-based photoluminescent light-emitting rechargeable glowstick. Unlike the normal chemical glowsticks that are usable only once until the chemical reaction is exhausted, these will last a lifetime of charges under normal light, no batteries required! Nightshine sticks glow more than 12 hours per charge. Recharges fully in just minutes when re-exposed to light. Completely maintenance free, these glow automatically in the dark. The darker it is, the brighter they glow. The Nightshine stick's glow technology works by absorbing and storing various kinds of natural and artificial light. When dark, the sticks emit a super-bright highly visible light by slowly releasing the absorbed light. Nightshine sticks are safe, non-toxic, cool to the touch, usable underwater, and perfect for both safety and fun uses. Each stick is approx. the same size as a regular 6" glowstick.

Charging tip: the brighter the initial light - the brighter and longer the sticks will glow. With proper charging, they will appear about as bright as traditional Chemical glowsticks.

In stock in 2 glow colors: Aqua Blue or Red Pink. (Yellow Green is out of stock.) The aqua blue and yellow green glow colors appear creamish white in daylight, while the red pink looks pink in daylight.
