Solar Powered water Bottle Cap

Light and water - pretty necessary for life. Well, heck, pretty essential for just about anything. This product brings all of them both together in an extremely functional way.

The lightest, brightest Light-emitting Diode limit offered. Transforms your liquid bottle into a solar driven lantern. This little, lightweight (only 2.6oz) cap fits on any "standard" water bottle (2" wide lips) such as Nalgene, Camelbak, GSI and most others, switching your bottle into a solar-powered lantern. With clean, green solar energy running your lantern there aren't any even more burned out batteries to be concerned about or change (adding to the currently poisonous landfills).
