Using new and efficient Chip on Board (COB) LED technology, Blinder Square lights produce a punchy 200 lumens on the front and 100 lumens on the rear, that will ensure you’re seen and safe in all light conditions. These lights have integrated USB recharging, are 100% waterproof and have a whopping 60-hour run-time when using eco flash mode. No charging cable is required for your Blinder, its integrated USB plugs directly into USB ports. It has a charge time of 4 hours and when your Blinder is running low on battery, a red LED will light up next to the button. Knog’s tool-less mounting system makes attaching your light incredibly simple and using silicone straps means there will be no chance of damaging your bike. A silicone strap is provided for bars and seat posts 22 – 32mm in diameter. A larger strap is also provided that will fit tubes and head tube profiles with a circumference of up to 200mm.
