the MiNewt X2 is all the light you'll ever need, unless you MTB at night...it doesn't quite have enough side wash for fast singletrack if mounted on the bars. on head it is great.
don't listen to the naysayers...this light is the business. led tech is very good
I have HID systems, halogen, and LED systems and i use the MiNewt X2 all the time
now because it is tiny, light, and throws a load of light
