The Fenix TK28R brings tactical lighting into a higher-performance tier with a flat-body design, a dual white-light system, and a dedicated red-light module that makes it highly versatile for operational, outdoor, and professional use. The core of the platform is a maximum output of 6500 lumens, a beam distance of up to 400 meters, runtime up to 102 hours, and an immediate-control layout built around a dual tail switch and a rear mode selector. Its high-strength aluminum alloy body, IP68 protection, and USB-C charging make it a serious tool for users who want real output, fast recharge times, and instinctive handling.

• Light output: maximum 6500 lumens, beam distance up to 400 meters, maximum runtime up to 102 hours, and 10 total operating modes split into 5 white-light levels, 3 red-light levels, red flash, and strobe.
• LED system: dual white-light emitters using Luminus SFT70 and Luminus SST70, plus OSRAM GR CSSPA1.23 red LEDs; declared color temperature is 6500K-7000K.
• Controls and handling: rear selector for white light, red light, and lockout/off; dual tail switch for instant Turbo, instant Strobe, instant Red Flash, and quick access to the main functions.

How to use

• Use the rear selector to choose the lighting group: left for white light, right for red light, center for lockout/off.
• For momentary light, tap the tactical switch; for constant-on, press it fully until it clicks.
• With the light off and unlocked, a full 0.5-second press on the tactical switch activates Instant Turbo.
• With the light on, the functional switch cycles through the available output levels: Eco, Low, Med, High, Turbo in white mode, and Low, Med, High in red mode.
• For charging, open the side port cover, connect the USB-C cable, and wait for the indicator to show full charge.
• For long-term storage, recharge the flashlight periodically and handle the batteries carefully to preserve performance.

Safety warnings

• Do not use 21700 or 16340 batteries, and do not mix batteries of different brands, sizes, capacities, or types.
• Do not disassemble the sealed head; doing so voids the warranty and may damage the flashlight.
• Do not shine the beam directly into anyone’s eyes, and keep the light head away from flammable materials.
• Keep the product out of reach of children.
• Use only compatible batteries and follow the correct insertion and charging procedures for 18650 cells.
