Fenix flashlights use advanced Cree LED emitters such as XP-L, XM-L2, and XP-G models, with Luminus SST70 LEDs in select tactical models. Founded in 2001 in Shenzhen, China, Fenixlight Limited manufactures flashlights from compact 85-lumen keychain lights to searchlights exceeding 10,000 lumens. The brand's digitally regulated circuitry keeps brightness consistent as the battery discharges, and anti-reflective coated lenses maximize light transmission. Models like the PD35 V3.0 deliver 1,700 lumens with beam distances up to 1,148 feet. The TK16 V2.0 produces 3,100 lumens using Luminus SST70 technology.
Aircraft-Grade Aluminum Construction
Fenix constructs its flashlight bodies from A6061-T6 aircraft-grade aluminum with Type III hard-anodized finishes. This alloy provides impact resistance up to 6.5 feet and keeps the flashlights lightweight. The hard-anodizing process creates a wear-resistant surface for use in law enforcement, military, and industrial settings. Bodies feature precision-machined threads, anti-roll designs, and heat dissipation fins on high-output models. The aluminum construction supports IP68 waterproofing for submersion to 2 meters for 30 minutes.
Rechargeable Battery Systems and USB-C Charging
The Fenix lineup includes rechargeable models with integrated USB-C charging ports in their high-capacity lithium-ion batteries. The ARB-L21-5000U battery offers 5,000mAh capacity for extended runtime in tactical models, while the ARB-L18-2600U powers compact EDC flashlights. Rechargeable models remove the need for disposable CR123A batteries, though many Fenix lights accept both rechargeable 18650 cells and primary batteries. Dual-fuel capability lets users switch between battery types as needed. Battery level indicators show remaining charge with color-coded LEDs.
Tactical and EDC Flashlight Series
Fenix organizes its product line into specialized series for specific applications. The TK Series features tactical flashlights for law enforcement and military use with dual-switch systems, instant strobe modes, and outputs over 3,000 lumens. The PD Series offers versatile duty lights with side and tail switches for mode selection, popular among security professionals and outdoor users. The E Series focuses on compact EDC flashlights, including keychain models under 3 inches long. The LD Series targets outdoor and search-and-rescue applications with extended runtimes. The LR Series delivers searchlight-level output in portable formats.
Professional-Grade Specifications and Waterproof Ratings
All Fenix flashlights meet or exceed ANSI/NEMA FL-1 standards for performance testing and measurement. The company manufactures products in its Shenzhen facility with ISO 9001 quality management oversight. IP68 waterproof ratings ensure submersible operation to 2 meters, while operating temperature ranges span -31°F to 113°F across most models. Reverse polarity protection prevents circuit damage from incorrect battery installation. Toughened glass lenses with anti-reflective coatings resist impact and maximize light output. Fenix headlamps, bike lights, and camping lanterns use the same construction standards as handheld flashlights.
