Available through Markell, Streamlight Inc.'s TLR-1 and the TLR-2, strobe-equipped versions of its leading tactical gun-mount lights feature C4 LED technology and provide even greater brightness than earlier models equipped with power LEDs. The TLR-2 comes with an integrated laser sight, and both models provide 8,000 candela peak beam intensity and 160 lumens measured system output. The C4 LEDs are impervious to shock with a 50,000-hour lifespan. In addition, Streamlight's proprietary deep-dish parabolic reflector provides a long-range targeting beam with optimum peripheral illumination to aid in navigation. The TLR-2 features a 650-660 nanometer red laser for long-range targeting. Both TLR-1 and TLR-2 are made with 6000-series machined aircraft aluminum with a black anodized main body finish. The housing for the TLR-2s laser is fabricated from a high-impact, chemically resistant engineered polymer. Both models provide up to 2.5 hours of continuous runtime to the 10 percent output level, with solid state current regulation for consistent illumination level. The TLR-2 offers up to 2.5 hours when using the Laser/LED simultaneously.
