That candela figure works out to an effective positive identification distance of 56 yards and visual impairment out to 8 yards, both calculated from the published beam data. It uses an integrated battery pack. It weighs 14.1 oz in an aluminum body 5.6 inches long. Measured against the 362 handheld lights in the index, it lands among the brightest 10 percent for output (20,000 lumens), about in the middle for beam intensity (27,000 candela), among the heaviest 10 percent for weight (14.1 oz), and among the most expensive 10 percent for price ($300). It is one of 71 entries in the index that qualify as a light in the same 4,000 lumen and up class.
