Fenix WF25RM is a professional service flashlight that offers exceptional technical parameters for demanding users. It combines reliability, high performance and multi-purpose use. It is equipped with a white light with 3000 lumens short-term output and ultraviolet 365 nm light with 500 mW output. The blacklight allows, for example, quick authenticity check of documents and banknotes or inspection of liquid leaks. Power is provided by a Li-Ion battery type 21700 with a capacity of 5000 mAh, which is charged directly in the flashlight using the included cradle with USB cable. The flashlight simply clicks into the cradle when charging. The cradle is equipped with mounting holes so that it can be screwed onto a wall or table, for example. The charging cable can be detached from the cradle and the flashlight can be charged outside the cradle. In addition, the USB-C charging connector is also fitted directly to the battery, so the flashlight can be easily charged without the charging cradle.

The Fenix WF25RM features a total of five white light modes with up to 77 hours runtime and one UV light mode. It uses a button ergonomically placed on the side to operate. The tailpiece features an integrated carabiner for hanging. The flashlight has a built-in safety circuit. When it is switched to the two highest white light modes and the spotlight comes closer than 1 cm to the object to be illuminated, it will automatically reduce the power to low mode to prevent possible damage.

Excellent technical specifications, waterproof and shockproof design predestine this flashlight for use in harsh outdoor conditions. When on duty, it will be especially appreciated by police officers, firefighters, rescue workers and mountain service. It will also find popularity with repairmen and technicians, security agencies and facility security.

All flashlight parameters (lumen output, battery life, waterproof, range and shock resistance) are measured in accordance with ANSI/NEMA FL 1-2009.

Using the Fenix WF25RM Flashlight

From manufacture, there may be an insulating cap inside the flashlight on the battery. Remove it before first use.

To switch on/off, press the button located on the side of the flashlight for approximately 0.5 seconds. With a short press of the button you can switch between power modes 30 - 150 - 400 - 1000 lumens at any time during operation. To release the UV light from the off state, double-click. The highest BURST mode of 3000 lumens can be activated by holding the button for 1.2 seconds. When released, the flashlight will switch back to the mode from which you started the highest output.

Ultraviolet light on indication - When the blacklight is on, the indicator in the side button flashes alternately red and green as a warning that the invisible ultraviolet light is active. If the battery is almost dead, the indicator flashes red only.

Intelligent proximity sensor - The flashlight has a built-in safety circuit. When it is switched to the two highest white light modes and the spotlight gets closer than 1 cm to the object to be illuminated, it will automatically reduce the power to low mode to prevent damage to the object by strong light and glare from reflected light. The function is not active for UV light.

Turn off/on proximity sensor - To turn off the function, loosen the battery cap of the flashlight, then press the side button and tighten the end cap again. Turning the function off is indicated by three flashes from the flashlight. Replacing the battery will automatically reactivate the function.

Charging - snap the flashlight with the charging connector facing inward toward the cradle. Alternatively, if the charging cable is disconnected from the cradle, attach the magnetic connector of the charging cable to the connector on the flashlight. Plug the other end of the cable into your computer, or USB mains adapter or car adapter. The side indicator lights up red while charging. When fully charged, it will light up green. Charging a fully discharged battery takes approximately 2 hours and 45 minutes using a 3A power supply. The flashlight cannot be used while charging. The battery can also be charged outside the flashlight using the integrated USB-C connector - plug the USB-C cable into the side connector next to the plus pole, the indicator light in the plus pole of the battery will be red during charging. When full charge is reached, it glows blue or green.

Intelligent overheat protection - due to the fact that the flashlight reaches high power, it experiences temperature rise. If the temperature of the flashlight exceeds 60 °C, an automatic power reduction occurs. As soon as the temperature drops below 60 °C, the output will gradually increase again.

Battery charge indication- The flashlight always indicates the battery charge status three seconds after switching on. Green indicates sufficient state of charge (100% - 85%), flashing green (85% - 50%), steady red (50% - 25%) and flashing red indicates a critically discharged battery (25% - 1%). If the battery is discharged, the flashlight will gradually switch automatically to lower power modes. When the lowest power setting is reached, the battery charge indicator will begin flashing red to remind you to recharge or replace the battery.
