Streamlight's TLR-3 compact, rail-mounted tactical light is designed to bring superior brightness to compact and sub-compact weapons used by law enforcement and military through the use of power C4 LED technology, which offers two to three times the output of Super High Flux LEDs. At 2.32 ounces and 2.71 inches in length, the TLR-3 is constructed from light-weight, impact-resistant engineering polymer casing. It provides 4,100 candela peak beam intensity and 90 lumens measured system output, and features a parabolic reflector that produces a concentrated beam with optimum peripheral illumination.
