The Streamlight TLR-7 SUB USB is a high-performance rechargeable weapon light designed for subcompact handguns, delivering 500 lumens of brightness with a 141-meter beam distance to enhance target visibility in low-light conditions. This versatile rail-mounted light offers flexible power options, compatible with either the Streamlight SL-B9 USB rechargeable lithium-ion battery or a standard CR123A lithium battery to suit your patrol, range, or carry needs. Ambidextrous paddle switches enable easy operation from either side, providing both high and low output settings to adapt to varying lighting scenarios, while a durable anodized machined aluminum construction ensures reliable performance in demanding environments. The unit carries an IPX7 waterproof rating and a safe-off feature to prevent accidental activation, preserving battery life during transport and storage. At only 2.39 ounces with the CR123A battery and measuring 2.51 inches in length, it remains lightweight and compact for subcompact pistols such as the GLOCK 43X, SIG SAUER P365, and Springfield Armory Hellcat. An added user-enabled strobe function provides tactical versatility, and with assembly in the USA and a limited lifetime warranty, the Streamlight TLR-7 SUB USB stands as a dependable, high-visibility accessory that enhances both safety and shooting effectiveness.
