Fenix TK25R
Tactical Multi-Mode Flashlight

3'600 lumens. UV. Red. Red/Blue. – The torch built for professionals who need it all.

The torch for professional operators – far more than a light source

Professionals need equipment with no compromises. The Fenix TK25R is built precisely for that standard: a tactical multi-mode flashlight that combines high-output white light, UV functionality, red light and a red/blue flash signal in a single, rugged housing. With 3'600 lumens in turbo mode, an innovative dual tail switch concept and eleven carefully designed light modes, the TK25R delivers exactly what law enforcement officers, security personnel and rescue teams need in the field: instant response, versatility and absolute reliability.

Dual tail switch – instant access to turbo and strobe

In the field, seconds matter. The TK25R’s dual tail switch was designed precisely for these moments: two independent switches at the rear of the torch provide immediate access to turbo mode (Instant Turbo, 3'600 lumens) and strobe (Instant Strobe) – no pre-selection, no delay. A rotary dial switch on the body selects the operating mode: Duty (white light), Tactical Support (side lights with UV, red and blue) or Lockout (safety lock against accidental activation). This combination makes the TK25R one of the fastest multi-mode tactical torches available.

11 light modes for every mission – from document checks to warning signals

What sets the TK25R apart from conventional tactical torches are its six Tactical Support modes, emitted via the side-mounted LEDs in the head. The 365 nm UV light is the go-to tool when identity documents, banknotes or forensic traces need to be checked. Red light (15 lumens) preserves night vision during low-light operations. The red/blue flash function provides an instantly recognisable warning signal – whether at traffic stops, incident cordons or search and rescue operations. Two side white light levels (30 lm / 150 lm) offer wide-area flood illumination for close-range work.

IP68 & drop resistance – built to withstand demanding conditions

The TK25R is machined from A6061-T6 aerospace aluminium – the same material used in aviation and military equipment manufacturing. The Type III hard anodized finish protects the surface against abrasion, saltwater and chemicals. With an IP68 rating, the torch is permanently waterproof to 2 metres and has passed a 1.5-metre drop test. The integrated thermal protection steps down output automatically once the housing reaches 60°C, then gradually restores the preset brightness level once cooled – protecting both the LED and electronics from heat damage during sustained high-output use.

USB-C charging – mission-ready in 1.5 hours

The included Fenix ARB-L21-5000 V2.0 (21700 Li-ion, 5'000 mAh) charges directly inside the torch via the built-in USB-C port – no separate charger, no battery swap in the field. A full charge takes approximately 1.5 hours. A low-voltage warning blinks red when the battery level drops below a critical threshold, reminding the user to recharge in good time. The maximum runtime of 55 hours in low mode ensures the TK25R remains operational throughout even the longest shifts.
