Water Bottle + Light = Bottlelight

Here is a simple formula that helps to reduce your luggage load while camping. The Bottlelight combines portable UV water purifier with a camping light. The bottle saves space and merges two essential must-haves. The carabineer on the top adds to the portability and dash of functionality.

How it works:

  • The top consists of two pressure casted aluminum parts with an inner sealing.
  • These become a watertight housing for the PCB, the battery and the UV and LED light unit.
  • A USB port can charge the battery for 10 hours of 30 Lumen while the 45° reflector at the bottom provides a plain and not reflecting light source.

    But if you’re shining a light into water, it creates a diffused effect (especially if the skin is matte, like in a plastic milk bottle) so why the reflector at the base?

    Put the LED light at the bottom, so it’s always shining directly into the water and you have a lantern.

    If you replace your clear plastic with a white semitransparent plastic, the light will defuse better and it will look brighter.
