The flashlight has a lightweight construction made of anodized aluminum, which allows for proper heat dissipation and guarantees its resistance to total immersion in water (up to 2 m), a fall from a height of 1.5 m and penetration of dust and small solids. The high IP68 protection class makes the flashlight ideal for use in harsh weather conditions, whether used in the city, in the woods or while driving in the mountains.
Thanks to its small size, low weight (157 g with battery) and quick release function from the handlebars, the BC21R V3.0 Bicycle Flashlight can also be used as a standard handheld flashlight. If you supply the ALD-08 adapter, the flashlight can be mounted on a bicycle helmet, which further allows you to use the flashlight as a headlamp during activities that require free hands. The bike mount has a function to quickly detach the flashlight from the handlebars. To do this, you just need to press the locking lever and slide the light out of the clamp. The set includes silicone adapters, which allow you to accurately fit the holder to the diameter of the handlebars in the range of 28 to 35 mm. They also allow us to adjust and lock the tilt of the flashlight within 15°.
The Fenix BC21R V3.0 flashlight uses a Luminus SST40 LED that emits a maximum light output of as much as 1,200 lumens. The light produced is neutral in color, does not tire the eyes, provides accurate color rendition and the ability to recognize more details in night vision conditions. The maximum range of reflected light in turbo mode is 142 meters, which in both urban and wilderness conditions provides excellent visibility and the ability to react early to the situation on the road. The Fenix BC21R has a wide light beam that provides a comfortable field of view, especially when cornering or riding over rough terrain.

Power supply The power source is a 2600 mAh 18650 battery, which, when charged, provides nearly 10 hours of operation in 600 lumen mode, or up to 132 minutes in 1200 lumen turbo mode (total runtime). The battery is charged via the built-in USB-C port, so we don't have to worry about buying an additional charger. The high charging current of 2 A allows the attached battery to be fully charged in just 2 hours. It's worth noting that we can use the flashlight during charging (low and medium mode only), although this will, of course, affect the extended charging time of the battery. We can control the level of battery charge thanks to the LED located in the switch, which simply and clearly informs us about the energy status (the function works only with 18650 batteries from the Fenix ARB-L18 series). We can alternatively use disposable CR123A batteries to power the flashlight.
Status of the battery level indicator:
- red flashing LED: critical level 1-25%
- red diode: low level 25-50%
- green flashing diode: medium level 50-85%
- green LED: high level 85-100%
The Fenix BC21R V3.0 offers 4 continuous light modes: low→medium→high→turbo and a flashing light with 400 lumens. A single metal button is used to turn on/off and change brightness, which also activates the battery level indicator. Simple and intuitive operation is a definite advantage of the bike flashlight, especially in busy urban areas.
The flashlight remembers the last used brightness level. When you turn it on again, the flashlight automatically activates in this mode (memory function). A low battery warning is automatically activated when the defined voltage level drops (flashing battery level indicator LED). The flashlight also uses overheating protection in turbo mode. For the safety of the electronics, after reaching 60° C, the controller automatically reduces the brightness by a few lumens, allowing the turbo mode to be activated again.
The light performance was tested under laboratory conditions using the ARB-L18-2600 battery.
