Describing this light as bright is a serious under-statement. Using new COB technology, Blinder X produces a punchy 200 lumens that will ensure you're seen and safe in all light conditions. It features a grid pattern that makes this Blinder one of Knog's most individual lights ever. The graphic flash pattern has 8 different modes and is also available as a rear light to make a unique pair. The Blinder Square has integrated USB recharging, is 100% waterproof and has a whopping 60-hour run-time when using eco flash mode.
