As a retired law enforcement officer I want flashlights that I can bet my life on. I carry 3 flashlights in my truck at all times that put out 400, 1000, and 3500 lumens. The 3500 uses 9 AA batteries. I also have a matching set in my TT . I have a 1000 lumen "lantern" in the TT for lighting up larger areas. Most of these lights came from Menard's and have lifetime warranties. I have had some of them for over 5 years. They are sold under the Guidesman brand.
