Moon X-Power ADJ850 High Power Rechargeable Front Bicycle Light Black

The Moon X-Power 850 Front Light features 2 Cree XM-L T5 high brightness LEDs and offers up to 850 lumen output with 7 different light modes ranging from constant to flashing.
The Moon X-Power ADJ850 front light is water resistant and is powered by the seperate 7.4V compact battery pack. Charging is via the provided wall charger. The head unit is constructed from CNC aluminium with cooling fins to the rear.

This new version (ADJ) of the X-Power 850 features a dual beam same as last year but now each beam can be adjusted vertically. This makes it possible to set one beam for close proximity and the other at a longer distance. This version is also supplied with a clamp type handlebar bracket rather than the wrap-around rubber mount. Slightly heavier than the standard X-Power 850 but a little more adjustable.
