The rail-mounted TLR-1 HPL produces a wide, 1,000 lumen beam pattern with brighter peripheral illumination and superior downrange performance. Mounts directly to all Picatinny rails and weapons with Glock-style rails. The deep dish parabolic reflector produces a long-range beam with optimum peripheral illumination. Durable anodized aluminum constriction, scratch-resistant coatings and waterproofing to 1m for 30 minutes make the TLR-1 HPL a durable and powerful light.
