In a low-light or no-light environment the Streamlight TLR RM 1 Tac Light and Red laser can help you identify and successfully engage targets. The 500 lumen, 5000 max candela, light has a strong central beam with a distance of 140 meters and optimal peripheral illumination. The LED light and laser have an estimated run time of 1.5 hours. The strobe function has an estimated run time of 3 hours and the laser alone can run up to 60 hours. Battery life is preserved with the Safe off feature which prevents accidental activation. A mode selector toggle lets you switch between the light, the laser, or both for activation. When mounted on your long gun you can choose either push button activation or pressure switch activation. The pressure switch cable exits the unit at 90 degrees for improved wire routing through the remote retaining clips. The pressure switch is attached to the Picatinny rail using the retaining clips.
