  1. Excellent Design 5 Star Review

    Posted by on 15th Jan 2021

    This light is very well designed. Larger than what I like for EDC, but great for general use. I very much appreciate both modes of operation (tail switch and side switch). The light does get hot where I normally hold it forcing me to change hand positions, especially during Turbo and High modes.

  2. Outstanding Light 5 Star Review

    Well made and well thought out light. I appreciate the tactical tail switch along with the side switch for the normal mode switching. Great power in a compact easy to carry package.
