The Streamlight TLR RM 1 Tac Light and Red laser can help you identify and successfully engage targets in a low-light or no-light environment. With a strong central beam with a distance of 140 meters and optimal peripheral illumination the TLR RM 1 produces 500 lumens, 5000 max candela, of light. 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. The ergonomic push button switch is located on the rear of the TLR RM 1 for easy activation.
