Features:

Beam:
The Light & Motion ARC Li-ion Ultra uses a proprietary peened aluminium reflector to ensure a super clean, even beam pattern with no jagged edges or dark spots. While others are satisfied to use intergrated lamps and reflectors originally designed for movie projectors, they spared no expense to give your eyes the best quality light available. Whether you mount the ARC Li-ion Ultra on your head or bar, the bright center spot and clean fill light will give you the confidence to ride any trail, or road at speed.

Power Settings:
Two output levels provide multiple burn times. Start up the ARC Li-ion Ultra by double clicking the power button on the rear of the light. The light comes on in the full 13.5w power mode; putting out a jaw dropping 675 lumens of clean, daylight balanced light and giving you 5 hours of run time. Press the button again for low power; 10w and the slow flashing LED confirms the low setting for 6 hours at an equally incredible 550 lumens of even, white light output.

Reserve Mode/Shutoff:
Batteries don't like to be fully drained. The ARC Li-ion has a built in low battery warning LED that gives the user feedback of when the battery has approximately 5 minutes left of run time. Further warning occurs when the light output dims significantly at exactly 1 minute before the system turns off automatically. Shutdown occurs to prevent battery deep discharge and maintain the overall life of the battery. Some manufacturers’ state that the ballast shuts off before the battery would be damaged. However, the tests show that the ballast will continue to light the lamp below the recommended battery shutoff voltage and that shutoff circuitry is necessary to protect the battery from deep discharge.

Mounting:
The ARC Li-ion Ultra comes with both a over-sized (25.8-31.8) compatible bar mount as well as the super adjustable and rugged Cabeza (helmet) mount as standard- Forget about the debate about which is best; helmet or handlebar mount? Decide for yourself. It is as easy as removing a screw and switching mounts. Both the helmet and handlebar mounts also feature neat break-away disks which means even if you don’t see that low hanging branch, or nasty rut your light head won’t take the punishment. Multi adjustable and simple, the mounts let you put the light where you need it and keep it there.

Charging:
The Light & Motion ARC Li-ion comes standard with our Lithium Ion Turbo Charger. The Turbo Charger quickly charges your battery to 80% in 2.45hrs and the tops it off in an additional 2.25 hrs. The CC-CV circuitry ensures optimal battery life by not overcharging the cells. LED indicators signal 80% and fully charged states and when the charging is complete the batteries can be left on the charger indefinitely to maintain their maximum charge state. Additionally, the Turbo Charger accepts wall voltage from 90-260 volts, so charging in the United States as well as internationally is not a problem.
