The 2013 version of the Vis 180 had a 50 lumen primary LED. In 2014 the light was upgraded to a 70 lumen output, but otherwise is physically identical. When purchasing the Vis 180, make sure you get the new, brighter version. The colors "Brown Shugga" and "Silver Moon" are the 2014 version with 70 lumens. Other colors will be previous years' less-bright versions.
