TK
The Fenix TK30 is a round-body LEP handheld light rated at 500 lumens and 1,200,000 candela. That candela figure works out to an effective positive identification distance of 379 yards and visual impairment out to 53 yards, both calculated from the published beam data. It runs on 21700 and is rechargeable. It weighs 7.1 oz in an aluminum body 6.2 inches long. Measured against the 362 handheld lights in the index, it lands among the dimmest 10 percent for output (500 lumens), among the most intense 10 percent for beam intensity (1,200,000 candela), on the heavier side for weight (7.1 oz), and in the most expensive quarter for price ($270). It is one of 61 entries in the index that qualify as a light in the same 500 to 999 lumen class. The closest listed comparison is Fenix TK30R, the same brand's light in the same 500 to 999 lumen class, priced at $300.
