The Titan 4000 OLED is the most powerful bike light we've ever made. The Titan's design ethos was inspired by endurance desert racing – to pack power in a minimalist profile. A low and wide footprint optimizes airflow over the aluminum chassis enabling for rapid cooling. With so much power available on tap, it's hard to grasp why you'd need anything more than this. Powering the Titan 4000 OLED is a brand new 60Wh 4-Cell Battery achieving 2 hours of runtime at maximum power. The Titan 4000 OLED features a high contrast OLED display that provides live runtime remaining, battery information, and light modes.
