I got a Princeton Tec Surge recently, and I've been using it quite a bit. I quickly discovered this $25 flashlight puts out more light than my 9P Surefire, with a better beam, too. It has a really nice beam: a 'hot spot' in the center of an oval diffused beam; about the same size as my SF 9P, but *much* brighter. Burn time with alkalines, (Duracells) included in the purchase price, BTW, is listed at 3-5 hrs. I put in a set of NiMH batteries, to keep operating cost down. This light is really bright for it's size and cost. I like the thumb switch, and positive detents for on and off, with the 'middle' position giving you the option of quickly turning the light on and off. Considering there are 8 AA batteries inside, the light is surprisingly compact; with an oval cross section, smaller than a D cell flashlight, and shorter than most 2 C cell flashlights. This compact light has a lot going for it; I wish my SureFire flashlights had the nice hot spot in the center of their beams, like the Surge does. My only complaint about this light is that it's too big to carry with me all of the time, except in a jacket pocket. Anyone else find any shortcomings for this light I haven't found? This light really seems like a very good buy, in comparison to other 'high end' and more expensive lights.
