Mounting:

Forget about the debate about which is best; helmet or handlebar mount? Decide for yourself. The ARC 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- 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.

A few years ago Light & Motion set the standard for HID lighting systems with the ARC. This year we have refined it and made the light that Mountain Bike Magazine called “the best out there” even better. The ARC turns night into day and the new compact Slimline NiMH battery doesn’t take up a water bottle cage. The High Intensity Discharge (HID) lamp provides 675 lumens of intense natural light that is 3 times brighter than comparable halogen systems. A NEW light weight battery, multiple output levels, low battery warning and auto shutoff are just a few features that make the ARC better than ever…

Power Settings:

Two output levels provide multiple burn times. Start up the ARC by double clicking the new more positive power button on the rear of the light. The light comes on in the full power mode; putting out a jaw dropping 675 lumens of clean, daylight balanced light and giving you 3 hours of run time. Press the button again for low power and the slow flashing LED confirms the low setting for 3.5 hours of a still incredible 550 lumens of even light output.

Reserve Mode/Shutoff:

Batteries don't like to be fully drained (who does?). The ARC has a built in low battery warning LED that gives the user feedback of when the battery has approximately 15 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.

Charging:

The Light & Motion ARC comes standard with our Multi-Chem Charger. The Multi-Chem Charger quickly charges your battery in 2 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.

ARC Battery Pack

Water bottle cages are becoming valuable property these days especially on the new generation of full suspension mountain bikes, so we eliminated the need to use one to carry our new Slimline battery. Whether you mount it on the top tube, seat post, or slide it easily into your jersey pocket, or hydration pack our 10.8v NiMH battery is incredibly small yet powerful. Now you can bring enough water to actually ride for 3 hours after the sun sets!

Beam:

The Light & Motion ARC 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 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.
