• Up to 225 lumens of tactical light for 1.5 hrs on two 3V lithium batteries
• Six output levels in three operating modes; optimized for critical or general applications
• Intelligent memory provides fast tailcap selection of the light you need in momentary or constant-on.
• Premium Cree Q5 LED and optimized reflector deliver a clean, smoothly focused beam at all levels
• Aircraft grade aluminum body designed for tactical operations with strike bezel, grip ring, and two-level tailcap switch.
• Waterproof to IPX-8 standardf

Three pre-programmed lighting modes. Each provides two instant options for the situation at hand. Intelligent design makes selection easy and intuitive. Turn the bezel to select the two-level mode that meets your immediate need—for tactical level lighting and strobe to overwhelm a suspect, or high-low settings for general or tactical use. Then use the tailcap switch for instant access to the level you need now, in momentary or constant-on. And because the TK12’s intelligent memory circuitry memorizes its last mode when you activate the light, you’re usually in the right mode as soon as you turn the light on. And Fenix’s advanced digital power regulation circuitry maintains constant output as it maximizes the life of the light’s two CR123A Lithium batteries.

Tactical features and dependability. A tough and practical body clip made from high ductility steel with Ti coating lets you securely attach the light to your belt, pocket, gear strap, or wherever it’s most accessible for you. Plus the TK12 features an anti-roll, slip resistant body design. The tactical tail cap switch includes a momentary-on function. Another great feature of this light is

Made tougher. The heavy-duty aluminum body has a durable type III hard-anodized finish that resists dents, scratches, and abrasion. Finely machined wear-resistant trapezoidal threads and O-ring seals make all Fenix lights waterproof to IPX-8 standards.

• Cree Premium (Q5) 7090 XR-E LED—the highest quality LED in the world—has a lifespan of 50,000 hours

• Three two-level lighting modes, easily selected with a quick twist of the bezel:
• Mode 1: Output A: 50 lumens (12 hours), Output B: 225 lumens (1.5 hours)
• Mode 2: Output A: 5 lumens (120 hours), Output B: 90 Lumens (5.5 hours)
• Mode 3: Output A: Strobe (3 hours), Output B: 225 lumens (1.5 hours)
• OP textured reflector, throws beam over 200 meters
• Toughened ultra-clear glass lens with anti-reflective coating optimizes throw on the most efficient output modes
• More effective heat sink technology protects the LED from overheating, while optimizing efficiency and power consumption
• Uses two 3V CR123A lithium batteries
• Anti-reverse connection circuit protects against misaligned batteries
• Tactical tailcap switch with momentary-on function
• Anti-roll, slip-resistant body design
