Princeton Tec IMPACT XL Diving Light

IMPACT XL: We took the traditional look and feel of handheld halogen lights and added in our Maxbright LED to make the Impact XL. With a rubber overmold and rugged construction, the Impact XL is durable enough for any conditions. And with a burn time of up to 50 hours, this compact light is sure to be there when you need it. REGULATED LED / CONSTANT BRIGHTNESS: Princeton Tec lights that feature regulated LEDs have a sophisticated regulating circuit that maintains initial brightness as long as the batteries have sufficient voltage. Traditional lights are very bright initially, but immediately begin to dim and continue to dim until the batteries are drained. Constant Brightness is a term used to describe products that have regulated LEDs. HEATSINK TECHNOLOGY: Princeton Tec has developed proprietary ultralight heatsinks 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 heatsinks, Princeton Tec lights can burn at extreme brightness levels for long periods of time. The heatsink may be incorporated internally or externally depending on the product and its application. LED OPTIC COLLIMATOR: A collimator gathers all available light from an LED in the form of scattered rays and re-emits the light as parallel rays, making it more optically efficient than a standard reflector. Princeton Tec calibrates each collimator to the type of LED and application of each light. With proprietary optimized collimator / lens systems, Princeton Tec continues to advance LED technology.
