***** 5 out of 5 stars

If you're commuting and want LIGHT, this is the brand to get.          They also make 1200 and 900 lumen models if you're not moving at quasi motorcycle speeds. I was on the verge of buying a Niterider 1200, but the high/low functionality and landing light brightness sold me on this.
