TK
The Fenix TK25R is a round-body LED handheld light rated at 1,000 lumens and 20,000 candela. That candela figure works out to an effective positive identification distance of 48 yards and visual impairment out to 6 yards, both calculated from the published beam data. It runs on 18650 and is rechargeable. It weighs 6 oz in an aluminum body 6.2 inches long. Measured against the 362 handheld lights in the index, it lands on the dimmer side for output (1,000 lumens), on the less intense side for beam intensity (20,000 candela), on the heavier side for weight (6 oz), and about in the middle for price ($120). 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 Fenix LD35R, the same brand's light in the same 1,000 to 1,999 lumen class, priced at $110.
