Totally sealed solar power unit - molded in from the top (outside) of the cap so there’s no possible contact with the contents of the bottle
Handy waterproof switch on the cap that lets you change from the white LED (bright), to red (preserves your night vision), or turn it off completely.
Leave the red light on all night (minimal energy draw) so you can easily find the bottle; then switch it to white if you need a light!
The water-bottle and cap combo weighs only 11 oz.
The LightCap stands 8 ¼" tall and 3 ¾" wide and has a 32 oz capacity.
With just a four-hour charge of sunshine the LightCap will stay bright for hours while the rechargeable Ni-Cad batteries will last for at least 300 cycles.
