I got one some time ago and run it as I did with my first blue MiniMaglite back in the year 2000, with Energizer Photo Lithium. It is a game changer with the light and now that we have access to German made Xenon bulbs it couldn't get any better.Not long ago Maglite was selling incan versions of the dark blue (or very similar) in AA, solitaire, 2D and 3D. They may still have some. They call it midnight blue.
