Those Surefire lights are great... they are very bright (much brighter than a 3xD cell maglite) and have very focused beams. They're good stuff.... and they can be expensive, too!

I found a similar low end light made by Dorcy. They make a lot of crappy little C and D cell plastic junk lights, but the one I found is called the Spyder. It's an aluminum cased unit that uses 2 lithium cells and a xenon bulb like the Surefires. The beam isn't as focused, but it is HELLA bright. Has the button on the end, so it can be useable in 'tactical' situations.. hehehe.
