The new PT 1L, 2L, 1AA and 2AA are the smallest and most light-weight additions to Streamlight’s handheld tactical products. The combination of their small size and power LED makes them among the brightest tactical personal lights available, ideal for a variety of low-light tactical situations. They provide up to 180 lumens and 50 hours of runtime. Each weighs less than 3.5 ounces and measures under 6 inches long, and requires either one or two CR123A lithium batteries or “AA” alkaline batteries. The PT 2L is also gun mountable, attaching to long guns with Picatinny rails.
