I own one of these, and just so you know - this model of P2D was before the "pre-flash" fix, which means when switching modes, the light very briefly starts at maximum output and then quickly fades down to the selected level. Not a huge deal, but turning the light on low in a small room looks like an explosion with dark-adjusted eyes.
I'd recommend instead some of the JetBeam warm emitter-option lights, particularly the Element; it's a simpler and more elegant design, runs on a common battery (AA), and most people find the rich Cree Q3 warm tint more appealing than the Rebel 100's somewhat bland color (the Rebel was also recalled for premature aging/yellowing issues.)
