The Nightstick TAC-300B is a round-body LED handheld light rated at 180 lumens and 9,150 candela. That candela figure works out to an effective positive identification distance of 33 yards and visual impairment out to 4 yards, both calculated from the published beam data. It runs on CR123A and is not rechargeable. It weighs 4.4 oz in a polymer body 5.5 inches long. Measured against the 362 handheld lights in the index, it lands among the dimmest 10 percent for output (180 lumens), in the least intense quarter for beam intensity (9,150 candela), on the lighter side for weight (4.4 oz), and among the least expensive 10 percent for price ($40). It is one of 24 entries in the index that qualify as a light in the same under 500 lumen class. The closest listed comparison is Nightstick USB-320, the same brand's light in the same under 500 lumen class, priced at $50.
