I actually have the same light. Awesome light output. Not the greatest beam pattern though. It just throws light in an ever expanding cone shape, so the stray upward light just blinds oncoming people/cars. I made a light shield for mine though.

Check to make sure your battery was not part of the recall L&M had several years ago. If your battery is part of the recall batch, you could get a free replacement, or whatever they are offering for recalled batteries.
