The Nightstick LGL-150 is a rifle-mounted LED weapon light rated at 600 lumens and 12,100 candela. That candela figure works out to an effective positive identification distance of 38 yards and visual impairment out to 5 yards, both calculated from the published beam data. It runs on CR123A and is not rechargeable. It weighs 4.2 oz in an aluminum body 3.7 inches long. Measured against the 148 weapon lights in the index, it lands on the dimmer side for output (600 lumens), about in the middle for beam intensity (12,100 candela), about in the middle for weight (4.2 oz), and among the least expensive 10 percent for price ($70). It is one of 54 entries in the index that qualify as a light in the same 500 to 999 lumen class. The closest listed comparison is Nightstick TCM-550XL, the same brand's light in the same 500 to 999 lumen class, priced at $90.
