The ideal solution for XC racing, with an impressive output and no compromise on technology in this sleek unit. Reflex Technology means this featherweight still packs a punch on the trail, but lowering the output allows the light to have crossover appeal for those who also have a rural commute or even a light weight pack ride. 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.Key Features: Weight: 186g, Lumens: Max 1450 (Reflex 2200), Runtime: 2 - 36 hours, LED Configuration: 2 x White XPL2, Battery: 5800mAh Lithium Ion, Rechargeable: Through Case USB, Charge Time: 6 hours, Material: Anodised 6063 Aluminium, Water Resistance: IP6, Length: 107mm, Head Diameter: 46mm, Race MK15, QR Handlebar Bracket (31.8mm - 35.0mm), Fast Charger, QS Guide.
