Krill Lamps are the ideal replacement for the chemical glowsticks - whilst offering the same benefits of the glowstick for low level lighting the Krill lamps offer a few more.
The main feature of the Krill lamps is that they are battery powered & can be turned on and off as required.
Krill lamps are waterproof to 50m & very lightweight (3 oz including batteries) making them ideal for diving & many outdoor activities such as camping, fishing & hiking - also, they don't attract insects & can take some knocks.
