The Beaver Electra LED Strobe and Torch is a superb combined LED Light and Flashing Strobe, powered by 3 x AA batteries (not included). This dual purpose light aids safety by increasing your visibility and helps maintain contact with others in low visibility or at night, together with providing a handy sized 130 lumens back up LED Torch. 

We have used these strobe lights off the back of a dive boat in the Red Sea for night diving to help identify/locate our boat.

Don't forget to maintain any torch 'o' rings with the occasional clean and silicone grease.
