Exposure Joystick with Helmet Mount - $189.95

With seven years under its belt, the Exposure Joystick Mk7 has continually evolved as Exposure has grown to be a leader in the performance lighting market. Now sporting a boost in output to 400 lumens and Exposure's new Optimized Mode Selector, the lightweight Joystick Mk7 with Helmet Mount continues to light the way. The Joystick's low weight and one-piece design was a significant departure from the separate battery and light units that once dominated the market. If you've ever snagged a power cord and had your singletrack tunnel go dark, then you know the appeal of self-contained lights. And, weighing in at under 90 grams, the Mk7 won't cause the fatiguing bobble-head effect of hefty lights.The Joystick's 2900mAh Lithium ion battery is enclosed within the Joystick's aerospace grade, exquisitely CNC'd aluminum body. The extensive machining, however, isn't just to look cool. It's actually designed to help heat transfer -- to physically cool the light. Packing one Cree XPG R5 LED, the Joystick Mk7 can generate excessive heat. One way it's managed is through the weather-tight body, the other way it's managed is with 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 feature found here on the Joystick Mk7 is Exposure's 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 and back-up batteries, or to even charge other USB-powered devices. - $189.95
