The Streamlight TLR-7 X 500LM CR123A FDE is a cutting-edge rail-mounted tactical light designed for versatility and performance, delivering 500 lumens of brightness with a 140-meter beam distance to illuminate targets clearly in low-light conditions. This multi-fuel unit operates seamlessly with either the Streamlight SL-B9 USB rechargeable lithium-ion battery pack or a standard CR123A lithium battery, offering flexible power options to match your mission or range routine. Ambidextrous rear paddle switches provide intuitive control for high and low modes, while the safe-off feature prevents accidental activation and preserves battery life when not in use. Crafted from durable anodized machined aluminum, the TLR-7 X stands up to demanding environments, and its IPX7 waterproof rating ensures dependable performance in wet weather or immersion scenarios. Weighing just 2.64 ounces with the SL-B9 battery, it remains lightweight and unobtrusive on the firearm, attaching securely to a Picatinny rail without hindering grip. Finished in a sleek Flat Dark Earth, this light complements modern platforms and is suitable for nighttime operations, home defense, or precision shooting.
