The SureFire X400VH MasterFire is a pistol-mounted LED weapon light rated at 350 lumens and 12,000 candela, with White and IR output. That candela figure works out to an effective positive identification distance of 37 yards and visual impairment out to 5 yards, both calculated from the published beam data. It carries an integrated ir aiming laser, listed with an <0.7 mW IR laser and a 120 mW IR illuminator. It runs on CR123A and is not rechargeable. It weighs 4.9 oz in an aluminum body 4.9 inches long. Measured against the 148 weapon lights in the index, it lands among the dimmest 10 percent for output (350 lumens), on the less intense side for beam intensity (12,000 candela), on the heavier side for weight (4.9 oz), and among the most expensive 10 percent for price ($699). It is one of 20 entries in the index that qualify as a light in the same under 500 lumen class. The closest listed comparison is SureFire X300V, the same brand's light in the same under 500 lumen class, priced at $499.
