When camping one of the main essentials is a water bottle, not many leave without one. So its nice that a company decided to incorporate that with a bit of technology to make an easy portable light.
The lamp isn't the full bottle, but just the cap itself. When placed onto the bottle it creates a very clever and convenient way to have a lamp handy at all times.
The cap fits the standard 2-inch wide mouth water bottle and the site claims that it is the brightest LED cap available. Although oddly the site doesn't say how long it takes for the solar battery to charge up. It is currently being sold for $19.95.
