The multipurpose rechargeable Fenix E04R flashlight offers up to 300 lumens of white light with a beam distance of 46 m (ANSI). It is powered by a built-in 400 mAh Li-pol battery, which is charged via a modern USB-C port directly in the flashlight. An additional light source includes the main red light and a side colored warning light (red, blue, RGB), making it ideal for both sports and emergency situations. The total weight is only 41 g, making the flashlight suitable for everyday carry. Thanks to the integrated 360° rotatable clip, you can flexibly attach it to clothing, a belt, a cap, a backpack strap, MOLLE webbing, or a headlamp strap. Its versatility can thus be utilized not only by hikers and runners but also by cyclists and DIYers.

The Fenix E04R offers a total of six constant lighting modes (white and red) with a runtime of up to 87 hours and five colored flashing and pulsing modes with a runtime of up to 23 hours.

All flashlight parameters (luminous flux, battery runtime, waterproofing, and beam distance) are measured in accordance with the ANSI/NEMA FL 1-2009 standard.

Operation and Activating Warning Signals

For maximum clarity, the flashlight is equipped with two switches (one for the main white/red light, the other for the side warning light).

On/Off: To turn the white light on or off, press and hold the main light switch for about 0.5 seconds. Double click the main light switch to turn on the red light mode. To turn on the side colored light, press and hold the side light switch for 0.5 seconds. The flashlight has an intelligent memory circuit and will turn on in the last selected output of the white or side light.

Output Selection: When the light is active, outputs are cycled through by a short click of the respective switch. The white light cycles through 1 - 25 - 100 - 300 lumens. The red light cycles through 5 - 12 lumens. The side light cycles in the following order: red-blue flash - red flash - blue flash - RGB pulse - RGB chase.

Lock/Unlock the flashlight - with the light turned off, press and hold both switches simultaneously for 3 seconds. The light will blink twice to indicate entering the locked status. To unlock, press and hold both switches simultaneously for 3 seconds again; the flashlight will unlock and illuminate in the lowest white light mode.

Battery Level Indication - each time the flashlight is turned on, or after a single click of the switch when the light is off, the indicator LED in the switch will light up for three seconds. A solid green light indicates 85 - 100% capacity, a flashing green light indicates 50 - 85%, a solid red light indicates 25 - 50%, and a flashing red light indicates a critically low battery (less than 25%).

Low-voltage Warning - if the battery voltage drops below the preset level, the flashlight will automatically downshift to lower brightness levels. Upon reaching the lowest output, the battery level indicator will flash red. In such a case, we recommend recharging the flashlight as soon as possible to prevent the built-in protection circuit from turning off the battery and shutting down the light.

Intelligent Overheat Protection - if the flashlight temperature reaches 60°C or above, it will automatically step down the output in small increments to reduce the temperature. Once the temperature drops below 60°C, the flashlight will gradually recall the preset output.

Charging

• Connect the USB-C end of the charging cable to the side charging port of the flashlight and plug the other end into a computer, power bank, USB wall adapter, or USB car adapter.
• During charging, the indicator light displays red, and it will turn green when fully charged.
• The normal charging time is approximately 2 hours using a 5V/1A power source. The battery has no memory effect, so the flashlight can be recharged at any time.
• The flashlight can be used while charging, except for the highest output in the white light mode.

Warning

• Do not disassemble the sealed parts yourself, as this will void the warranty.
• If the flashlight flickers, fails to switch to a higher mode, or does not light up, it may be due to one of the following reasons:
  • The battery is low – recharge it.
  • The flashlight is locked – press and hold both switches simultaneously for 3 seconds to unlock it.

Warranty

Statutory two-year warranty.
