- Uses one Cree XM-L2 T6 neutral white LED with better color rendition
- Powered by one 18650 rechargeable Li-ion battery or two CR123A Lithium batteries
- Optimized Dual Distance Beam System
- Micro USB direct charging
- Built-in over-charge, over-discharge protection
- Battery Level Indication
- Low power warning reminds when battery replacement needed
- Over-heat protection to avoid high temperature of the surface
- New-type quick-release bike mount for easy and secure adjustment of the light direction
- Four brightness levels and one flashing mode
- Digitally regulated output maintains constant brightness
- Made of aluminum alloy with excellent heat dissipation design
- Waterproof to IPX-6 standard
- The Flash mode will flash at 380 lumens and 100 lumens alternately.
- The bike light is equipped with red side lights, it will be activated simultaneously by default. This side red light will be constant-on as the main light on and flashing red when main light flashes.
- The above-mentioned parameters (lab tested by Fenix using one Fenix ARB-L2-2300 18650 rechargeable Li-ion battery) are approximate and may vary between the bike lights, batteries and environments.
*The runtime of the Turbo brightness level is the accumulated time. The runtime can be longer when uses 18650 battery of larger capacity.
Press and hold the light button for 0.5 seconds to turn ON/OFF the light.
With the light on, click the light button to cycle through Low→Mid→High→Turbo→Flash.
- As with any performance light, the bike light builds up heat when runs for an extended period. Intelligent circuitry in the bike light downshifts the light to lower brightness level to guard against overheating.
- The bike light retains the last-used brightness level.
- When the battery power level is critical, higher brightness levels can not be activated, the bike light is programmed to cycle through lower brightness levels.
Battery Level Indicator
With the light off, single-click the light button, the side light will indicate the battery power level conditions, and then go out after 5 seconds.
- Side light constant-on (sufficient power level): 60%-100%
- Side light slow flashing (low power level): 20%-60%
- Side light quick flashing (critical power level): 1%-20%
Low Power Warning and Intelligent Output Downshift
Low Power Warning: With the light on, when the battery level is lower than 20%, the light button will blink red constantly, to remind you to downshift to a lower brightness level to extend runtime or recharge the bike light.
Intelligent Output Downshift: If non-stop use is needed, the light will downshift to a lower output level to extend runtime. When it downshifts to the flashing mode, the bike light will go out soon. Please stop riding and replace the battery or the bike light.
Operation Points: Remove the anti-dust plug at the bottom of the bike light to reveal the charging port, and plug the Micro USB end of the USB cable into the light’s charging port, then connect the other end of the USB cable to a USB power adaptor.
Charging Indicator: The indicator light in the bike light blinks red to indicate the charging process has begun. The indicator light turns solid green when the battery is fully charged.
- Turning on the bike light under charging state is not recommended by Fenix. But it will be okay if under emergency situations, the bike light can light up Low and Mid output.
- Once charging is completed, disconnect the USB cable from the light and be sure to secure the anti-dust plug cover.
- Fenix recommends using a power adaptor with output over 5V 1.5A. It takes about 4 hours to fully charge the bike light.
- The bike light can be connected to the USB cables for digital products such as mobile phones with standard Micro-USB charging port.
