Hope Vision 2 LED Endurance Front Light: The all NEW LED light – boasts some impressive features. Beautifully machined, this tiny light packs a big punch with it's twin high power 5w LED's pushing out 480 lumens. Endurance version includes 2 x 2 cell battery packs. In tests the 7.4v Li-ion battery will last for a minimum of 1hr 45mins of burn time with the intelligent charger returning that in just 3 hours. Universal Mount: This mounts to the NEW universal handlebar clamp (std and oversize compatible) or the NEW aluminium helmet mount (both items supplied as standard, along with short and long connecting wires – no expensive add on's to upgrade!) The Small Li-Ion Battery Pack: (which is the same one found in the stem mounted light) is now held in a custom made neoprene soft pack. The battery has built-in charge, discharge and short circuit protection. The connectors are fully sealed and totally waterproof (IP67). The light has a simple on/off push switch on the back. The soft bag option is small enough to fit under most stems, top tube junctions or slip into a hydration pack or jersey pocket. Our NEW universal handlebar clamp and helmet mount are both CNC machined to the same high standards the rest of our products achieve. No nasty plastic here! Ample velcro fastenings are also supplied. Stem Mount: The 7.4v Li-Ion battery pack (which complete with it's machined aluminium casing is about the size of a mobile phone) sits un noticed beneath the handlebatr stem, in the same mounting bracket as the HID.

The clip system holding the battery also allows for quick changes – ideal for Endurance racing or those longer winter rides when you don't want to be standing around getting cold and struggling with wires and fastenings.
