Very happy chappy here

Used the XP500 on high setting for most of my commute, only turning up to the 500 lumens "overdrive" mode when I hit the tree-lined cycle path.
You've no doubt seen the beam shots over on road.cc and I can confirm that for me, this little light (and it is small!) puts the illumination right where you need it. There's a nice bright central section and enough spill to light up the edge of the road and the area in front of the tyre. I felt much more confident and was able to ride at my normal pace (16-20mph).
My only slightly negative comment, is that pressing the button to cycle through all the modes includes "off" despite the fact that you can turn the light off with a long press of the button... IMHO it might have been better to require a long press to switch both on and off, saving short presses to cycle the modes. Overall though, a great wee light
