The Streamlight TLR-6 HL handgun light for Glock 43x/48 combines a high-power LED and integrated green aiming laser in an ultra-compact, contoured package that delivers 300 lumens with 4250 candela and a 130-meter beam, while offering flexible runtimes: a 20-minute run time when using LED only or LED/Laser combo, and a 5-hour run time when the laser is used alone. This model runs on one proprietary Streamlight SL-B2 rechargeable battery and ships with a two-bay USB-C charge case and three batteries, providing ample charge options for extended use. Ambidextrous push-button switches on both sides ensure intuitive operation, and the battery can be replaced with the light mounted on the firearm without re-sighting the laser. The weapon-mounted unit is securely attached to a Picatinny rail with a durable, impact-resistant polymer housing that withstands 1-meter drops, and it features windage and elevation adjustment screws mounted in bushings to help maintain laser zero. At just 2.5 inches in length and 1.12 ounces with battery installed, it remains lightweight and streamlined, with serialized construction for positive identification and a limited lifetime warranty.
