Loaded with a 170 lumens of light the Blinder Arc 1.7 gives riders total visibility and freedom at night, all from a super-compact, super-light, USB rechargeable, 100% waterproof, integrated silicone package. Equipped with one of the latest high-intensity XB-D Cree® LEDs, keeping motorists and road users at bay the Arc 1.7 uses an elliptical beam of 16° vertical and 24º horizontal beam making the light visible to others at over 1000m.

“One last note, these lights are all light, i.e. not heavy, relative to their competitors. I initially doubted their ruggedness, but a year later, and suffering the abuse of regular commuting, trail thrashing and having plastic hockey pucks dinged off them in the basement, by my kids, they’re going strong and show little wear.” - Red Kite Prayer
