This cannister torch is the ultimate primary source of light for cave divers! At maximum output of 4500 lumens you will have 4.5hours of time with a very narrow beam of 7 degrees. The battery pack is easily rechargeable with the recharger and can be used as a normal power bank with a USB. It comes very handy after your dive, when your mobile’s run out of power.
