Let me introduce you to the EagleTac Flashlights.
First off EagleTac has three product groups. They are the Personal, Tactical and Military Line of flashlights. The groupings have more to do with battery types than what the end user will be using them for. The three battery types are AA, CR123A and 18650.
Below I have scanned in the Comparison Table from a brochure I was sent. Please ignore the crease down the middle, I have been carrying this around with me everywhere lately.
Missing from below is the third light in the power house Military line up - the M2SC4.
