Quantity:

Three years ago, Light & Motion set the standard for HID systems with the incredibly light and bright ARC Li-ion. Now we have combined our amazing ARC HID light with an even more amazing 9-cell Li-ion Ultra battery. Code named Mufasa like the li-ion king’s father; the ARC Ultra leaves no doubt who is the real king of the jungle in HID lighting systems. Weighing only 486 grams, the ARC Ultra’s 9-cell Lithium-Ion battery is half the weight of comparable NiMH batteries yet gives you unparalleled run times for even the most epic nocturnal adventures.

Beam:

The Light & Motion ARC Li-ion Ultra uses a proprietary peened aluminum reflector to ensure a super clean, even beam pattern with no jagged edges or dark spots. While others are satisfied to use integrated lamps and reflectors originally designed for movie projectors, we 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 and with complete confidence.

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; who does? 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. Tech note: HID lamps use a ballast. Some manufacturers’ state that the ballast shuts off before the battery would be damaged. However, our 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 our 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 our helmet and handlebar mounts also feature our 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 our mounts let you put the light where you need it and keep it there.

Charging:

The Light & Motion ARC comes standard with our Multi-Chem Charger. The Multi-Chem Charger quickly charges your battery in 3.5 hours and ensures optimal battery life by not overcharging the cells.

LED indicators signal the charging is complete and batteries can be left on the charger indefinitely to maintain their maximum charge state. Charging is monitored by measuring the change in temperature over the change in time (dT/dt), which is the method recommended by all NiMH battery manufacturers.

Additionally, the Multi-Chem Charger accepts wall voltage from 100-260 volts, so charging in the United States as well as Internationally is not a problem.
