Fenix BC25R LED Bike Light

The Fenix BC25R is one of the best and most compact commuter bike lights available this year! This Bike light has all the features you want with an impressive output of 600 Lumens. Fenix designed the BC25R with a anti-glare facula that will help you prevent the accidental blinding of oncoming pedestrians or vehicles. You can easily adjust the Fenix BC25R with the quick release bike mount that is included with your purchase. Two different sized handle bar shims are included to fit a wide variety of bicycles and sizes. Removing the BC25R from you bike is easy, but charging it is even easier. The Micro USB port can be accessed quickly for easy charging. The built-in 2600mAH Li-ion battery charges in approximately 3-4 hours. A full charge will give you a run time of 2 hours on the Turbo 600 lumen output with a visibility of 347 feet of distance. The Fenix BC25R is also IP66 rated, which helps you commute during those heavy spring showers and it prevents dust particles from causing damage to your bike light.

Intelligent Memory Circuit
The light memorizes the last selected brightness level on General mode. When turned on again the previously used brightness level will be recalled.
Overheat Protection 
The light will accumulate a lot of heat when working on Turbo mode. The light will automatically step down a few lumens to reduce the temperature, but turbo mode can be reselected.
Low-voltage Warning
One of the indicators flashes when the battery level is critical. When the voltage level drops below a preset level, the bicycle light is programmed to step down to a lower brightness level until Low output is reached. To ensure normal use, the bicycle light will work until the battery runs out.
