The Ma Xx-D is the race weapon that pushes lighting boundaries in lightweight power. Continual upgrades with this year's inclusion of Reflex Technology sees the Ma Xx-D develop to a huge 2400 lumen output. That's enough light for any full speed heart pounding descent. With the new addition of the OSD & capacitive switching for accurate burn time countdown & programming ease it's packed with innovative British technology. Reflex Technology enables the light to intelligently adjust its own brightness to suit your riding. A combination of gradient, acceleration & cornering forces are interpreted to match output to your need for light while automatically maintaining the burntime you have selected. OLED Status Display (OSD) advances Exposure Lights' pat. pend. display technology. The OLED panel gives program & mode information before switching to a burntime countdown. During charging, the OSD shows the percentage of stored energy in the cells so you know how long it is before you can get back to riding. Capacitive Switching increases the ease of mode changing. The entire backcap of the light acts as a button so you can touch any point to change the mode. It intelligently senses pressure so whether you're wearing big winter gloves or just not wanting to take your eyes off the route ahead, simplified switching is a touch away. Optimised Mode Selector means that you can easily select from a concise number of programs to provide the optimum lighting for your ride. The primary design feature of Exposure Lights, Cable Free Design removes the hassle of cables & straps utilising the superb range of brackets for speedy, rock solid attachment.
