Pushing out 2200 Lumens, the Reflex Mk1 torch takes over as Exposure's flagship model. Lighter than the MaXx-D and brighter than the Six Pack, it's the light source high-speed night riding demands. Brightness is one aspect of a quality nightlight, and with two new technologies that build on Exposure's industry leading designs, the Reflex Mk1 aims to provide the ultimate night riding experience.

One of those new features is Reflex Technology. This game changer automatically adjusts the Mk1's power output to suit riding conditions. Remotes have helped prevent one-handed, hail-mary attempts at pressing mode buttons, but -- even with today's mega-wide bars -- handlebar real estate can be scarce. When the Reflex Mk1 leads the way, it senses g-forces and slope to respond with the proper brightness -- independent of rider input.

When ascending standard uphill grades, the Reflex drops power output to conserve juice in the 11600mAh Lithium ion battery. Once it senses acceleration or a downhill grade, the Reflex opens up the flood gates to unleash full candle power. This keeps your hands steering, and your eyes focused on the trail.

The other new feature found on the Reflex Mk1 is Exposure's Optimum Mode Selector. OMS offers 11 pre-programmed settings to provide the optimum lighting for ride conditions. After all, the requirements needed for a high-paced trail ride are quite different than 24hr race, or a week of commuting -- and OMS lets you custom tune the light for any of those conditions.

For example; in the first OMS setting, the Mk1 will push 2200 Lumens and will automatically switch between 410 Lumens depending on its surroundings. This setting will last 3 hours worst case, 12 best. It's safe to assume you'll enjoy 4-5 hours of light in this mode. There are two more automatic modes that reduce both the highest and lowest outputs for even longer battery life (6 - 24hrs, 12 to 36hrs).

If you want to forgo the automatic feature, there are eight more OMS modes that offer varying high, medium, and low settings for any cycling condition from commuting to 24-hour racing. The OMS modes are selected using the power button located on the back of the unit. A new digital display offers accurate feedback of battery life and easy navigation of OMS.

The Reflex Mk1, like all Exposure lights, is constructed from aerospace grade aluminum -- not just because it's durable and light -- but also because aluminum helps disperse heat. As do the CNC-machined fins around the front bezel, which houses the three XML LEDs and high-tech resin lens. This helps keep the internals cool by transferring heat to the atmosphere and not the lamp itself.

Further protecting the inner workings, is Exposure's patented Intelligent Thermal Management (ITM). If the internal temperature gets too high, ITM kicks in and automatically drops the power level down to the next lowest setting. It will remain at the lower setting until the temperature inside the housing returns within normal operating range. This, and the weatherproof housing, ensures the light's battery and LED bulbs are safe from moisture, muck, and heat for a long life span.

A defining Exposure feature found here on the Reflex Mk1 is Smart Port Technology Plus. Essentially, it's a cylindrical plug on the back of the lamp unit that allows you to insert the smart charger. But, it also enables you to plug in accessories like a red LED taillight, back-up batteries, a remote, or even to charge other USB-powered devices. It will automatically recognize each accessory and configure the system to take a charge or power accessory lights.

The Exposure Reflex Mk1 has a two year warranty against defects in materials and workmanship

    First off, amazing CNC construction, making the light durable and attractive. The QR attachment to the bar is solid and easy to use, but does require an Allen key to adjust the angle on the bar which is slightly annoying. These are traits for all of the Exposure lights, the Reflex sets its self apart in technology and high amount of Lumen. The automatic light level adjustment based on speed quickly transitioned from slow speed climbs to steep descents. The light level always seemed appropriate and burn time did not leave me wanting. This is an expensive light, but if you are serious about night riding, well worth the money. -Brett C.
