Made from rare earth minerals, the Scooblite from Innovative Scuba Concepts is a reusable, rechargeable, and reliable light source. An environmentally safe item, it never requires batteries. Any light source, from sunlight to artificial lighting, can be used to charge it within a few minutes time. When fully charged, the Scooblite will first glow brightly, before dimming to a consistent illumination for about an hour. It will continue to glow at a lower intensity for a longer time period. The brighter the source used for charging, the brighter and longer the Scooblite will glow. It can be recharged with a flashlight or other light source at any time, even underwater.
