In the tradition of the original Light Cannon HID light, the Light Cannon eLED delivers an even brighter illumination and maintains this brightness throughout the battery life. The beam is wide enough for scanning the reef at night or exploration of the interior of a wreck. Colored filters and diffuser filters can be inserted inside the light for incredible video effects. Using the dovetail handle attachment you can use either the included pistol grip or (optional) lantern grip). It starts with a unique dual power electronic circuit to control the matched pair of 10-Watt LED's. Its water-cooled heat sink actually increases brightness underwater and improves burn time. For maximum illumination the Light Cannon eLed Light is the perfect solution. Unlike the standard glass envelope lamps used since Edison, the LED will not break when dropped. The life expectancy is well over 5000 hours. The light emitted by the LED (light emitting diode) is similar to sunlight and travels farther underwater than the more yellow light from an Edison lamp. In addition a power control circuit is built into the light to help maintain the same brightness throughout the discharge of a set of batteries. A tough O-ring sealed ABS and polycarbonate case with a front lens protected by heavy rubber boot, protects the components all the way down to 500' (152.4 meters). The Cannon eLED Light is powered by 8 disposable C"-cell alkaline batteries (included), or if you wish to upgrade it with a rechargeable kit the is available eliminating the need for replacement power cells. With alkaline batteries the light has a burn time of 9 hours on the high power setting and 14 hours on low. The Cannon eLED Dive Lights dual 10-watt LED's produces 825 lumens of brightness on high power and 530 lumens on low. The light provides a beam distance of 520' (158.5 meters) in high-mode and 431' (131.4 meters) in low-mode on land. The light measures 7.3" x 7.1" x 3.2" (18.54 x 18.03 x 8.13 cm) and weighs 36 oz (1.02 kg) with batteries. The Cannon eLED Light is equipped with a non-breakable locking switch that prevents accidental actuation when in your gear bag and also has a protective heavy rubber lens boot for drop protection. Light handle is a pistol grip design and comes with an adjustable rubber sleeved wrist lanyard. Light is available in multiple colors, comes with an owner's manual and is proudly made in the USA.
