The Nitecore BR25 is a lightweight (76 grams without battery) and compact bike light with an impressive output of 1400 lumens from the Luminus SST-40-W LED.
A universal handle bar mount is included with a quick release dismount design so the light can be removed from the mount to prevent theft and also to be used as a hand held torch.
Featuring a unique diffuse reflection design, which illuminates the road surface ahead and improved close range lighting around the front wheel. Unlike conventional bike lights the BR25s non-disruptive cut-off beam will not dazzle pedestrians or oncoming vehicles yet illuminates up to 163 meters ahead.
The Nitecore BR25 is compatible with a range of batteries including 21700 Li-ion (recommended for best runtime), 18650 Li-ion or CR123A cells (using included battery magazine). A Nitecore NL2150R USB-C rechargeable 21700 5000mAh 8A battery is included in the box.
Operation is via a single button interface which activates the light and changes between the four brightness levels and warning flash mode.
Brightness Levels, Runtime and Range Using Included 5000mAh 21700 li-ion battery:
Turbo: 1400 lumens - 2 hours 30 minutes - 163 meters
High: 430 lumens - 3 hours 15 minutes - 91 meters
Medium: 170 lumens - 12 hours - 50 meters
Low: 28 lumens - 60 hours - 20 meters
Warning Flashing: 1400 lumens
Advanced Temperature Regulation (ATR) regulates the output of the BR25 according to ambient temperature to protect the LED and maintain optimum performance. There is no pulse-width modulation on this model (PWM) meaning no flicker for reduced eye strain.
Waterproof to IP68 (2 meter submersible) and impact resistant from 1 meter.
