LED Lenser D14 Dive Flashlights 880042 are innovative, high powered dive flashlights that laugh at the obstacles deep sea diving throws at ordinary flashlights. The natural refraction of water makes it difficult to focus a flashlight beam over long distances underwater, a fact every scuba and deep sea diver is familiar with. That's why LED Lenser has equipped the D14 Flashlight with an axial collimator, which gives the dive flashlight extraordinary strength of focus, even underwater. These LED Lenser flashlights are strong enough to project a beam up to 180 meters underwater, and their state of the art cooling systems allows them to be used just as effectively on dry land, unlike competitors' dive flashlights. LED Lenser has built the D14 with magnetic components that don't corrode as quickly as metallic parts, and it's IPX8 waterproofing and sturdy construction allows it to be carried at depths of up to 197 feet. For a 150 lumen dive light that can be used just as well above and below the sea, choose the LED Lenser D14 150 Lumen Dive Light.
