Professional divers know that underwater, refraction rules out long ranges. Due to its axial collimator, the LED Lenser D14 diving flashlight attains a great strength of focus even at long ranges. Thanks to its unique cooling system, unlike other diving lights, the D14 flashlight can also be operated on land. Its beam distance when out of water is 590 feet and it is suitable for dives down to 197 ft. / 7 bar. Special magnetic parts allow for switch activation without corrosion over time on the mechanical parts.
