SureFire's X300V Handgun Weaponlight is the perfect addition to a nighttime shooting setup. It features two modes, a "normal" white light function and an IR mode. The "normal' mode produces a powerful beam of 350 lumens, which can temporarily impair the vision of your target. Alternatively, the IR function produces 120 milliwatts of infrared illumination, completely invisible to those without night vision devices. Both modes have a momentary-on and constant-on feature, momentary-on activates the light for as long as the ambidextrous toggle switch is held down and constant-on keeps the light active until switched off.
