Description

With an upgraded output of 200 lumens in flash mode and 75 lumens in constant mode, the BoostR 3 is brighter and more effective than ever. A larger battery delivers up to 70 hours of runtime, ensuring reliable, long-lasting performance for daily commutes or multi-day adventures. Combined with a precision-engineered lens system and our signature DayBright pulse pattern, you remain highly visible in all riding conditions from busy streets to open roads.

Advanced Reakt technology takes visibility even further by automatically adjusting brightness to suit ambient light. Enter a tunnel and it dims to preserve battery life; exit into bright daylight and it boosts output for optimal contrast. Reakt also includes an automatic brake light, flaring under deceleration for added safety in both constant and flash modes.

For group riders, Peloton mode prevents dazzling those behind you. When it detects another rider’s light close behind, it dims automatically, returning to its previous setting once they move on.

A specially designed lens and body configuration provide exceptional side visibility, helping you stand out in busy urban traffic. The 8° collimated spot lens delivers impressive long-range throw, giving you greater clarity and control compared to other products with similar outputs.

Crafted from CNC-machined 6063 aluminium and anodised in our iconic gunmetal grey, the Boost R 3 is built to endure. Rated IP67, it easily withstands harsh winter conditions without compromising performance. Despite this robust construction, the Boost R 3 remains lightweight at just 45g, ensuring premium durability without added bulk.

The BoostR 3 combines smart technology, exceptional runtime, and powerful visibility everything you need to stay seen, stay safe, and ride with confidence

Featured Technology

Day Bright – Day Bright Technology
Bespoke pulse pattern designed for daylight use which is more conspicuous than a regular pulse. And is visible over a kilometre away, even in the brightest conditions. DayBright mode will get you noticed. Be seen, be safe.

OMS – Optimised Mode Selector
Various programs in the lights can easily be selected to offer a choice of run times and modes. So you can find the right one for your ride, be it an all-night adventure or an intense blast.

REAKT – ReAKT Technology
Rear lighting that flares up automatically under braking. It can also intelligently adapt to the surrounding ambient light conditions to maintain maximum contrast and visibility. For example, brightening for street lit areas and moving into sunlight from shade.

Peleton Mode – Peloton Technology
Enables the rear lights to automatically dim down when the front light of the rider behind is detected. Preventing dazzling in a chain gang, it then flares when at the back of the pack for maximum safety.

ITM – Intelligent Thermal Management
Patented circuitry within the light will reduce power to the LEDs, if they go beyond the optimum temperature. Keeping the light as efficient as possible to maximise output and battery capacity. Once the light has cooled, the power is automatically restored.
