Krill Lamp

The Original Krill Lamp Last over 120 Hours on a set of 2 AA batteries (not included), with an overall rated life of +2000 hours. It is water proof up to 150 feet, and weighs only 3oz with batteries (about 3 chemical light sticks). The Krill Lamps in extremely durable, able to survive drops of 50 ft onto concrete slabs.

I understand the brightness on these is about the same as a 12 hour Cyaclume chemical light after it has been on for about an hour. Given that a $1 battery can run a Photon green/turquoise for 200 hours, the Photon may be a better alternative given its tiny size. Photons are not waterproof though it is about the size of a quarter in diameter, and 3 quarters thick.
