Throwing out a maximum of 3300 lumens that illuminates both far & wide, the Ma Xx is great for tackling challenging & technical terrain. Utilising both focussed & wide lenses, the Ma Xx-D lights up the edge of the trail without sacraficing on the reach of the beam. Youll never be surprised by a root or cranny, even in complete darkness. The Ma Xx-D boasts a standard output of 2500 lumens, but has the capacity to chuck out 3300 when in Reflex+ mode; illuminate the trail like its midday. Battery life is between 2 & 36 hours depending on what mode youre in, so youve got the juice to go all day & night. & with the Optimised Mode Selector offering 10 modes, there will always be the right mode for you. Reflex+ Reflex+ technology utilises two thermistors to detect wind chill, a gyro to detect gradient & an accelerometer to dim & brighten your light when you need it the most. When youre heading uphill, youre naturally going slower so need less light, so the light dims to conserve battery. Then as you descend & pick up speed, the light will boost to its full potential so you can see exactly where you going. The light will even dim to 5% when youre stationary to make your battery go further. It will do all this whilst maintaining the burn time that you have selected. Internal Thermal Management When the internal temperature of lights increase, they begin to lose power & become less efficient. Thanks to ITM technology, the internal temperature of Exposures lights is managed to maintain efficiency for the entire burn time. Oled Status Display The OSD panel provides programme & mofe information, & battery power/burn time when youre on the move. It also displays battery level when its charging.
