Reflex++ Reflex++

Reflex automatically adjusts the light to provide boosted output when riding hard and fast then intuitively dimming for the slower sections such as climbs. This is all to optimise battery capacity, to provide extra light when needed and save it when not required.

Reflex achieves this by using data from 3D digital accelerometers including gyroscope and thermistors. It continually analyses the data to make seamless adjustments to benefit the rider, probably better than the rider can. In reality it is a form of artificial intelligence. The selected run time will be achieved by averaging the output over the period.


An LED display panel that gives clear information on which mode the light is in, runtime remaining in hours and minutes, percentage charged and feedback information during OMS. Patent Protected.


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.


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.
