Exactly what's expected from streamlight - Streamlight TLR-7 X sub USB 500 Lumens LED Weapon Light

Although some might argue Streamlight is expensive, it truly is a case of "You get what you pay for" when buying from them. As this was purchased with the sole intent of permanent residence on my home defense pistol, I wanted something that came with trust and proven reliability. So far, I haven't been disappointed - thankfully I haven't been in a home-defense situation, but I'm confident this light will perform. It was really simple to install on my X-Macro Comp (1913 version with the number 4 insert), as well as programming the strobe function and learning how to activate it quickly. The light is extremely bright (500 Lumens) which allows me to quickly acquire the threat and the surrounding area. The strobe function works really well and will definitely disorient the threat, giving you precious seconds to eliminate any threat you may face.
