So called, because of the Chips On Board (COB) LED tech this light uses to give off its superior glow. Perfect for all traffic scenarios i.e. cars coming at you from the side, or to soften the glare from your mate's rear end in the peloton. With its 120° beam and reflective faceplate, Mr Chips makes sure you are seen not just from the front & rear, but from the side too. This bright bike lights long run times and lumen output of 80 lumens at the front and 44 at the rear ensures you are well seen up to at least 1.2km away, all night long. And its secret weapon? 2 x front & 3 x rear interchangeable straps so you can swap these lights between bikes with different sized seatpost and handlebars - including aero seatposts and oversize bars.SPECIFICATIONS Dimensions: 42x42x62mm Weight: 35g Materials: UV-Resistant Industrial grade silicone, Polycarbonate Housing, Polycarbonate Optical grade PMMA Lens, Hard-Anodised aluminium fascia.
