I'll make this short and simple - I never write reviews, but I've just been out on the bike to test out the new lights and couldn't help but report back at my delight, they are incredible, it is simply the best money I have ever spent on the bike (at £89 - 6th October 2012).
I wanted a light that I could train on at night, something where I could do 25mph down a pitch black country lane and it would light it up like a car - this light does just that, and what's more it does it on virtually the lowest setting!
I live in a village, one that hasn't yet invested in street lights, and one surrounded by narrow dark country lanes with often poor surfaces to navigate. I turned the light off and could not see my hand in front of my face (I am neither blind or wear glasses for clarity), I turn the light on and zoomed along in complete confidence that I could see everything with clarity. It has good spread to the side so everything is clear aswell as excellent distance.
Easy to setup, easy to charge, and I even like the light on the back which tells you approximately how much charge is left. I just hope the charge can live up to manufactures statements, and based on other reviews I've read it will.
For what's it worth, everyone I know who rides a bike will be getting one of these for Christmas.
