Designed for taking on the boat. It is fully waterproof and will float if it is knocked into the water. Includes a hand strap that you can tighten so you can’t lose it if you find yourself falling overboard.
Blindingly bright. Only niggles are that when turn it on, you have cycle through the other two modes (half bright & SOS signalling to turn off. Also, there is a small isolator that goes into the charging socket when the light isn’t in use, to prevent accidentally draining the battery which is handy. However, there isn’t anywhere to stow it when the light is being used,so there is a risk that it could get lost.
