The Nitecore TM12K is a flat-body LED handheld light rated at 12,000 lumens and 90,000 candela. That candela figure works out to an effective positive identification distance of 103 yards and visual impairment out to 14 yards, both calculated from the published beam data. It uses an integrated battery pack. It weighs 8.3 oz in an aluminum body 4.4 inches long. Measured against the 362 handheld lights in the index, it lands among the brightest 10 percent for output (12,000 lumens), in the most intense quarter for beam intensity (90,000 candela), in the heaviest quarter for weight (8.3 oz), and in the most expensive quarter for price ($230). It is one of 71 entries in the index that qualify as a light in the same 4,000 lumen and up class. The closest listed comparison is Nitecore EDC37, the same brand's light in the same 4,000 lumen and up class, priced at $160.
