Description: The T10 is a super long-throwing LED hunting light specially designed for outdoor hunting. It is available in 2 types: T10-HG (green light) and T10-HR (red light) for different preys. The T10 adopts Projection Compact green LED (about 550nm) or red LED (about 620nm), which can dispense with color filter. LED of high luminous intensity with super-concentrating reflectors creates extraordinary long-range beam! T10-HR’s light intensity up to 50600cd candela! The luminous flux is up to 342 lumens and the beam distance is 450 meters! The standard 1-inch diameter body is suitable for most mounts and can be easily mounted on shotguns with optional tail remote switches. T10 has high and low modes with beacon mode which is convenient for positioning in the field. IP67 rating, it can be used in heavy rain. The unibody construction of the T10 gives it a high rate of heat dissipation and shock resistance, and the drive circuit is with high-efficiency temperature control protection function, complementing the built-in multiple tiers of protection system, including low-voltage warning, reverse polarity protection. The veteran hunters know that the light intensity of hunting lights is more important than the luminous flux. Hunters can easily find hogs, wolves, foxes or even hares which are hundreds of meters far away, thanks to the help of T10 “Devil Incarnate”. Directions:Open the tail cap by twisting counter-clockwise, insert a charged quality battery with the positive terminal towards the bezel, and tighten the tail cap by turning clockwise.The flashlight has reverse polarity protection, the light will not be damaged by batteries inserted in the wrong orientation, but it will not turn on.
