CR123As are quite powerful yet compact. The assumption is that if you're running a tactical light, convienence of replacement batteries is not an issue.
I would recommend some sort of LED-based light, then pick up some cheap Chinese rechargeable CR123As. The LED-bulbs are self-regulated, so the cheaper Chinese cells can't fry them the way they tend to with Xenon bulbs.
