All I can say is WOW! I never new what I was missing. I received the E2e executive model as a birthday gift. I can't believe how bright this thing is. I'm used to my old 2 AA maglite. This thing is at least as bright as the 4D cell maglite I keep in my truck. The most amazing thing is that there are no rings or dark spots in the light. Just one perfect spot of bright white.
