{"product_id":"fenix-tk21r-rechargeable-tactical-flashlight","title":"Fenix TK21R Rechargeable Tactical Flashlight","description":"\u003cp class=\"product-lead\"\u003eThe Fenix TK21R is a rechargeable tactical flashlight rated at 3600 lumens maximum output with a beam distance up to 1575 ft (480 m), designed for law enforcement, security professionals, and first responders who need reliable high-output lighting under demanding conditions. It ships as a single configuration with battery, holster, lanyard, USB-C cable, and spare O-rings included.\u003c\/p\u003e\n\n\u003ch2\u003eInstant Access When It Counts\u003c\/h2\u003e\n\u003cp\u003eThe TK21R's dual tactical tail switch gives users two distinct control points at the rear of the light. The larger switch provides immediate access to Instant Burst mode: maximum brightness without cycling through lower levels first. For situations where a momentary-on technique matters, the forward clicky soft-press switch delivers precise, repeatable activation even under stress or with gloved hands. Having both controls at the tail means the light can be operated consistently regardless of grip orientation.\u003c\/p\u003e\n\n\u003ch2\u003eHigh Output, Long Runtime\u003c\/h2\u003e\n\u003cp\u003eAt its maximum setting the TK21R produces 3600 lumens and throws a beam to 1575 ft (480 m). Five modes (four brightness levels plus strobe) let users balance output against runtime, which extends to 72 hours 30 minutes at lower settings. The Luminus SFT90 LED is rated for 50,000 hours of use. Power comes from the included ARB-L21-6000 lithium-ion battery (6000 mAh), recharged through a hidden USB Type-C port; the port cover maintains the light's IP68 dust and waterproof rating when closed.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt for Field Use\u003c\/h2\u003e\n\u003cp\u003eThe TK21R body is machined from A6061-T6 aluminum with a matte, non-reflective finish. An internal dual-spring structure absorbs recoil and impact shock, making the light suitable for weapon-adjacent carry or rough handling. The strike bezel incorporates glass-breaking tips. The Advanced Pulse-Frequency Transmission (APF) system manages LED drive for consistent output. At 7.81 oz (221.4 g) with battery installed, the light measures 6.28 in (159.5 mm) in length with a 1.42 in (36 mm) head and 1.0 in (25.4 mm) body diameter.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e3600-Lumen Maximum Output:\u003c\/strong\u003e Luminus SFT90 LED rated for 50,000 hours of service life.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual Tactical Tail Switch:\u003c\/strong\u003e Larger switch for Instant Burst mode; forward clicky soft-press for momentary-on control.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUSB-C Fast Charging:\u003c\/strong\u003e Hidden port with waterproofing cover; included ARB-L21-6000 6000 mAh li-ion battery.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIP68 Rated:\u003c\/strong\u003e Dust-tight and waterproof construction with hidden charging port cover.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShock-Resistant Construction:\u003c\/strong\u003e Internal dual-spring structure and A6061-T6 aluminum body with strike bezel.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComplete Kit Included:\u003c\/strong\u003e Holster, lanyard, USB-C cable, and spare O-rings in the box.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eValue\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMaximum Output\u003c\/td\u003e\n      \u003ctd\u003e3600 lumens\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBeam Distance\u003c\/td\u003e\n      \u003ctd\u003eUp to 1575 ft (480 m)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMaximum Runtime\u003c\/td\u003e\n      \u003ctd\u003e72 hours 30 minutes\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eModes\u003c\/td\u003e\n      \u003ctd\u003e5 (four brightness levels + strobe)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLED\u003c\/td\u003e\n      \u003ctd\u003eLuminus SFT90, rated 50,000 hours\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBattery\u003c\/td\u003e\n      \u003ctd\u003eARB-L21-6000 li-ion, 6000 mAh (included)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCharging\u003c\/td\u003e\n      \u003ctd\u003eUSB Type-C (cable included)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWaterproof Rating\u003c\/td\u003e\n      \u003ctd\u003eIP68\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBody Material\u003c\/td\u003e\n      \u003ctd\u003eA6061-T6 aluminum, matte finish\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLength\u003c\/td\u003e\n      \u003ctd\u003e6.28 in (159.5 mm)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eHead Diameter\u003c\/td\u003e\n      \u003ctd\u003e1.42 in (36 mm)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBody Diameter\u003c\/td\u003e\n      \u003ctd\u003e1.0 in (25.4 mm)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight (with battery)\u003c\/td\u003e\n      \u003ctd\u003e7.81 oz (221.4 g)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eIncluded Accessories\u003c\/td\u003e\n      \u003ctd\u003eHolster, lanyard, USB-C cable, spare O-rings\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWarranty\u003c\/td\u003e\n      \u003ctd\u003eLimited lifetime (Fenix Lighting USA)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCountry of Origin\u003c\/td\u003e\n      \u003ctd\u003eChina\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThe TK21R suits law enforcement officers, security professionals, and first responders who need a high-output, field-ready flashlight with fast access to maximum brightness and reliable recharging via USB-C.

It does not accept standard CR123A or AA cells; it requires the included proprietary li-ion battery or a compatible 21700-format cell.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the difference between the two tail switches?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Fenix TK21R has two switches at the tail. The larger switch activates Instant Burst mode, delivering full 3600-lumen output immediately without stepping through lower brightness levels. The smaller forward clicky soft-press switch is designed for momentary-on use, giving precise control over when the light activates and deactivates, which is useful for signaling or low-profile illumination techniques.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes the TK21R come with a battery and charging cable?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. The Fenix TK21R includes the ARB-L21-6000 rechargeable lithium-ion battery (6000 mAh) and a USB-C charging cable. The charging port is hidden behind a waterproof cover to maintain the light's IP68 rating. A holster, lanyard, and spare O-rings are also included in the box.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eIs the TK21R waterproof?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Fenix TK21R carries an IP68 waterproof rating. The USB-C charging port uses a hidden, waterproofed cover that must be closed to maintain that rating. The internal dual-spring structure also provides shock resistance for use in demanding field conditions.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eHow long does the battery last?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eRuntime on the Fenix TK21R reaches up to 72 hours 30 minutes at lower output settings. At maximum 3600-lumen output, runtime will be significantly shorter. Five modes (four brightness levels plus strobe) allow users to balance output against battery life based on the situation.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eCan the TK21R be mounted on a weapon?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Fenix TK21R's internal dual-spring structure is built to absorb recoil and impact shock. No specific mount or rail adapter is listed among the included accessories; a compatible mount would need to be sourced separately based on the 1.0 in (25.4 mm) body diameter.\u003c\/p\u003e","brand":"Fenix","offers":[{"title":"Default Title","offer_id":67031053992307,"sku":"KRC-FNX-TK21RSFBK","price":175.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1926\/7025\/files\/fnx-tk21rsfbk.png?v=1791002232","url":"https:\/\/bulletproofzone.com\/products\/fenix-tk21r-rechargeable-tactical-flashlight","provider":"Bulletproof Zone","version":"1.0","type":"link"}
