Gemini TITAN 4000 OLED

  • $19999

Titan 4000 OLED is Gemini's most powerful light to date. 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.

The Titan 4000 OLED features a high contrast OLED display that provides live runtime remaining, battery information, and light modes. 

Powering the Titan 4000 OLED is a brand new 8000mAh 4-Cell Battery achieving 2 hours of runtime at maximum output.  The Gemini 4-Cell battery features a reversible USB Type-C port for both in/out charging of other devices. A durable outer shell made of high strength polycarbonate has yielded a increase in double the impact protection from the previous generation.

The handlebar mounted Titan 4000 OLED comes standard with a wireless remote that can pair with a helmet light for excellent fingertip control. New hybrid optics were developed to combine width and throw for superior trail visibility.
