The Knog Blinder X 1800 Front Bike Light is a high-output cycling headlight from Knog built for riders who push into low-light and no-light conditions and need a light that keeps up. At 1800 lumens maximum output it draws on 12 high-performance LEDs paired with a polycarbonate lens system combining 8 spot optics and a 4 wide-angle optics for a 23-degree beam angle that covers both path and periphery. The light chassis and mount are machined from 6061 aluminium and the entire system carries an IP67 waterproof rating for protection against rain mud and trail debris. An external 10000mAh lithium-ion battery pack mounts to the bike frame via a bottle cage boss bracket or velcro straps keeping weight off the light head while a multi-color LED indicator reports charge status at a glance. A handlebar-mounted remote button lets riders switch between 6 pre-programmed light modes without taking hands off the bars and the system fits handlebars from 31.8mm to 35mm.1800 lumen maximum output from 12 LEDs with 8 spot optics and 4 wide-angle optics in a 23-degree beam angleSix pre-programmed light modes range from 1800-lumen High Steady down to 650-lumen Eco Flash with up to 75 hours runtimeExternal 10000mAh rechargeable lithium-ion battery mounts to the frame to keep the light head compact and balancedHandlebar-mounted remote button toggles modes and shows battery charge level via color-coded LED indicator without stoppingIP67-rated waterproof construction on both the light head and batteryMachined 6061 aluminium light chassis and mount with compatibility for 31.8mm to 35mm handlebars via included shimsUSB-C rechargeable with charge status indication; yellow flash signals charging green short flash confirms charge completeOperating temperature range of -20 to 50°C (-4 to 122°F) for year-round use Lumens Front 1800 Recharge Type USB Battery USB Weight 125g (light); 210g (battery)
