Exposure Lights started with the Joystick and it remains the lightest, and most award winning helmet light in the range; with a more focused beam, and now with 1100 lumens the Joystick enables you to spot the terrain changes in the distance and the tight corners at your wheel.Intelligent Thermal ManagementPatented 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. Optimised Mode SelectorVarious 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.Specifications: LED Configuration - 1 x White XPL2, Lumens - Max 1100, Battery    - 3500mAh Lithium Ion, Runtime    - 1.5 - 36 hours, Rechargeable - Through Case USB, Charge Time - 4 hours, Weight - 93g, Material - Anodised 6063 Aluminium, Water Resistance - IP6, Length - 112mm, Head Diameter - 30mm,.In The Box: Joystick MK15, Handlebar Bracket, Helmet Mount, Lanyard, Fast Charger, USB Charge Cable, QS Guide,.
