The Fenix TK20R V2.0 is a duty flashlight: 3,000 lumens, 56,600 candela, a beam that reaches 1,558 feet, dual rear switches, and a 21700 cell that runs 48 hours on Eco. It is the light in Fenix's tactical line that most people should actually buy, because it has the throw of the bigger TK models in a body that still rides on a belt. Here is what the numbers mean and what it is like to use.

Lumens versus candela
Lumens is total light. Candela is how tightly that light is focused, and it is the number that predicts throw. The TK20R V2.0's 56,600 candela from a Luminus SFT70 LED is what pushes its beam out past 1,500 feet, which is far enough to identify a person or vehicle at the end of a long driveway or across a field. Plenty of lights claim 3,000 lumens; far fewer put them 500 yards away.
The dual rear switches
Tactical lights live on the tail, and the TK20R V2.0 has two switches there: one for momentary and constant on, the other for mode changes and strobe. You can run the light with a thumb without looking at it, which is the point of a duty light, and you never accidentally cycle modes when you wanted momentary.
Battery and charging
The included 5,000 mAh 21700 is a large cell for a light this size, and it is what gives the 48-hour Eco runtime. Charging is USB-C directly into the light, so there is no cradle to keep track of.
Durability
IP68 waterproof and rated for a 4.9-foot drop, which is duty-belt height onto concrete. Fenix aims this light at law enforcement and military use, and the build reflects it.
Carrying it
A light this size belongs on a belt. Our flashlight sheath collection covers molded kydex carry for tactical tubes, with the switches exposed so momentary works from the holster.
Who should buy it
Duty use, property and security work, or anyone who wants real throw with a tactical interface. If you want the same power in a slightly smaller pocket-clip body with a single tactical switch, see the PD36 TAC.
