This is a sweet tac-light with awesome ergonomics and some nice activation switch features. Very bright 150 lumen LED light. This has been mounted and flicked on and off about a handful of times, but never run for more than a few seconds at a time. Other than that it has just sat in it's box for the past 6 months or so, batteries out. Asking $125 shipped to the continental US which is a very good price on this light. Stats listed here. Please feel free to PM with questions. Thanks for looking.
