The Genesis light has 1 Max-Bright LED and provides 3-hours of regulated burn time on high mode, 5-hours of burn time on low mode and 24-hours of burn time in SOS mode. The Light has a narrow Beam angle that has a reach of approximately 341′ (104 meters) on land in low-mode and further than 584′ (178 meters) on land in high-mode. Princeton Tec has developed proprietary ultra light heat sinks to protect LED products from overheating. Even though LEDs operate at much lower temperatures than traditional incandescent bulbs, they still generate heat. If this heat is not dissipated, the LED will suffer irreversible damage. By using heat sinks, Princeton Tec lights can burn at extreme brightness levels for long periods of time. The Genesis Light is depth rated to 330′ (100 meters) IPX8, weighs 7.2 oz. (203 g) with batteries, and comes with an owner’s manual.
