Danger lurks in the darkest corners. With its staggering 500 lumen output, the X-21 Light Cannon has the ability to flush them out --- and then some! Its vapor-sealed, high-intensity bulb provides the sheer power…but it’s the parabolic , shaped silver, halide-coated reflector AND the optical grade, iridium coated, borosilicate glass lens reflector that combine to concentrate the beam to super-nova levels. Ideal for either hand-held or weapon-mounted use, the X-21 can take a punch --- its lamp assembly is spring-isolated for superior shock resistance up to 1250G! The aircraft aluminum body is O-ring connected for reliable, waterproof operation to depths of 100 ft. Lock Out bezel prevents accidental activation. Tail switch and crenellated bezel enhance the X-21’s tactical capabilities. Runs on 4 included lithium batteries. Color: black. Size: 10” long. Weight: 15 oz. Made in USA.
