TK17
The Acebeam TK17 (Osram) is a round-body LED handheld light rated at 1,500 lumens and 21,000 candela. That candela figure works out to an effective positive identification distance of 50 yards and visual impairment out to 7 yards, both calculated from the published beam data. It runs on 18350 and is rechargeable. It weighs 1.97 oz in an aluminum body 3.27 inches long. Measured against the 362 handheld lights in the index, it lands about in the middle for output (1,500 lumens), on the less intense side for beam intensity (21,000 candela), among the lightest 10 percent for weight (1.97 oz), and in the least expensive quarter for price ($65). It is one of 127 entries in the index that qualify as a light in the same 1,000 to 1,999 lumen class. The closest listed comparison is Acebeam T16S, the same brand's light in the same 1,000 to 1,999 lumen class, priced at $65.
