Hope Vision 2 LED Front Light: The all NEW LED light – boasts some impressive features. Beautifully made, this tiny light packs a big punch with it's twin high power 5w LED's pushing out a maximum of 480 lumens. Standard version includes 1 x 2 cell battery pack. 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 helmet mount (both items supplied as standard, along with short and long connecting wires – no expensive add ons 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. Stem Mount: The 7.4v Li-Ion battery pack (is about the size of a mobile phone) sits unnoticed beneath the handlebar stem, in the same mounting bracket as the HID. 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/mode push switch on the back. 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. All housings feature excellent waterproof sealing. Note the stem is not included and must be bought separately.
