The Streamlight TLR-8 X Sub is a compact, rail-mounted light and laser combo built for subcompact handguns, offering versatile performance with multi-fuel capability. It runs on either a CR123A lithium battery (included) or Streamlight’s SL-B9 USB-C rechargeable battery pack, delivering 500 lumens and a 141-meter beam distance. The unit features ambidextrous rear paddle switches with customizable high and low activation options, along with a safe-off feature to prevent accidental activation and preserve battery life. Built from durable, anodized machined aluminum, the TLR-8 X Sub securely attaches to a wide range of subcompact firearms without requiring hands in front of the muzzle. It includes a user-enabled strobe, offers long runtimes in laser-only mode, and is IPX4 water-resistant—making it a rugged and adaptable lighting solution for everyday carry, duty, or home defense.
