Underwater Kinetics C4 eLED Dive Light

The classic C4 primary dive light has received a major upgrade in this L2 model, increasing the lumen output up to 1000 lumens. The light uses airline-safe Nickel metal hydride batteries, which can be shipped in your luggage, unlike lithium batteries, which must be kept in the cabin during travel. This makes the rechargeable C4 perfect for travelling. These batteries are the same kinds used in the Prius hybrid cars, and can last for up to ten years - that's twice as long as lithium batteries used in some other lights.

UK's innovative optics system now concentrates 89% of the total lumens of the light into the center of the beam, reducing backscatter and greatly improving beam brightness. Typical lights only focus about 40% of their lumens in the center beam, meaning much of the lumen output is lost as stray light. The Hydralume heat sink in the light is exceptionally resistant to corrosion - our proprietary allow corrodes only 1/200th as much as aerospace grade aluminum alloys. This exemplies the high standards set on the C4 and other lights on our line to last their use a lifetime.
