Streamlight Inc.'s SL-20L and SL-20LP rechargeable flashlights are among the most powerful rechargeable handheld duty lights the company offers for law enforcement professionals and others who require extremely bright light in work environments. Both of the new full-sized, professional grade lights use a C4 LED to deliver up to 350 lumens measured system output, and 60,000 candela peak beam intensity for long- range beam distance. The lights also feature a deep-dish parabolic reflector, which optimizes peripheral illumination while providing a tight, focused beam. Each of the lights offers three microprocessor-controlled, variable intensity modes, as well as a strobe setting. The SL-20L and SL-20LP lights weigh 1.7 and 1.3 pounds, and measure 13.1 and 13.2 inches in length, respectively. The SL-20L is constructed from machined aircraft-grade aluminum with a Type II anodized finish and is available in black. The SL-20LP is made of lightweight, impact-resistant nylon polymer designed with a non-slip rubber comfort grip. This model is available in high-visibility yellow, safety orange or non-glare black.
