I don't have one of my own, but almost bought one after I saw a friends in action. As far as throw, it's not any less powerful than a standard. I've got a 4D standard Maglite, and the one I saw was the same thing only in LED. It was pretty impressive. However, DO NOT buy the standard and then one of those Nite-Ize conversion kits. They're total crap. <img src="/images/graemlins/mad.gif" alt="" /> I didn't buy it myself, but someone gave it to me for my birthday. Wish I hadn't opened it so I could have returned it. They're ok for the extended run time, but for everything else, they're crap. plain and simple. I say stick with standards.
