There was some interest in my recent lights purchase so I said I’d post up the details. You get a low weight light, enough lumens to comfortably see off road (the spot is a bit narrow but fine for helmet mounting). With just a little toggling between modes I was getting a 4 hour burn time. Price? £23. No, that’s not a typo! See link below.
