Streamlight TLR-7 X Sub USB Features The Streamlight TLR-7 X Sub USB delivers 500 lumens and 5 000 candela of output giving shooters a bright far-reaching beam for identifying threats in low light. Its multi-fuel design accepts either a single CR123A lithium battery or the included Streamlight SL-B9 USB-C rechargeable lithium-ion pack providing runtime of about 1.5 hours on CR123A or roughly 1 hour on the SL-B9. Ambidextrous rear paddle switches offer both high and low output options and a safe-off feature helps prevent accidental activation that would otherwise drain the battery. A user-enabled strobe function adds a disorienting option for defensive encounters. Machined from durable anodized aluminum the TLR-7 X Sub USB attaches via a rail grip clamp specifically designed for the Glock 43X MOS 48 MOS 43X Rail and 48 Rail models allowing quick installation and removal without ever placing hands in front of the muzzle. At 2.51 inches long and 2.64 ounces with the SL-B9 battery installed the light adds minimal bulk to a subcompact pistol s already slim profile. Mounting hardware is included for a secure repeatable fit. This combination of rechargeable convenience and purpose-built mounting makes the TLR-7 X Sub USB a strong choice for everyday carry and home defense use on a Glock subcompact pistol.
