The LED Lenser D14 is built to go where other flashlights simply can't function. Professional divers know that underwater, refraction rules out long ranges. Because of its axial collimator, the LED Lenser D14 attains an amazing strength of focus even at long ranges. Thanks to its newly-developed cooling system, unlike many other diving lights, the D14 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 mechanical parts, that could corrode over time.
Technical Specifications:
LED Lenser was founded in 1994 by twin brothers Rainer and Harald Opolka in their garage in Germany. Now LED Lenser has over 1000 employees, hundreds of patents and numerous design awards. There are a number of reasons to buy an LED Lenser flashlight, but one very good reason is that they stand behind their product with a five-year-warranty, wherein they will repair or replace the product and ship it back to you at their expense.
