5.0 Overall rating
The Nitecore BR25 bike light has a maximum output of 1400 lumens from the Luminus SST-40-W LED and is recommended to be used with the Nitecore NL2150R 21700 li-ion battery which comes included with the light. Alternatively, the light can be powered by 1 x 18650 (with a discharge current over 8A), 2 x CR123 single use batteries or 2 x RCR123 li-ion batteries, all of which need to be inserted into the included battery magazine before using with the BR25.
The BR25 features a diffuse reflection design which reflects the light to the road surface, forming a focused and bright, short range illumination area. It also ensures there is no blind spot beneath the front wheel and that the beam doesn't shine directly into the eyes of oncoming pedestrians or drivers.
The bicycle light offers four brightness levels and a warning flash, all of which are operated using the single button interface. A power indicator is built into the switch to ensure you know when it's time to recharge or change the battery.
The BR25 comes with a universal bike mount which provides fast and user friendly mount and dismount. Alternatively, the light can be used as a portable flashlight with a comfortable knurling design for excellent grip.
