The Photon 4 Enduro has all the functions of the Commuter combined with a 3 cell Li-Ion VisionStick battery.
This extends runtime to 6 hours on 4 watt high beam and 24 hours on 1 watt low beam or 4 watt flash mode.
The VisionStick battery can be
mounted to a bike with the
double battery bracket
(on a bottle cage
mount).
An expanding power lead stretches to 1.6m allowing for a variety of battery locations and light positions.
This lead also makes it possible to fit the LED head unit to the helmet mount bracket.
