I picked up a couple of these for half price after Christmas. It's a little shorter than the Dorcy 3xAAA 1w, but with a wider head. It's pretty light weight, light enough to hold in the mouth for hands free lighting. The rubber inlay also contributes to comfortable hands free use while biting down. My wife really likes hers. The low level is pretty dim with wide, but very dim side spill. Plenty good for finding your way around the house or outside without much ambient light. The high level has much more useable spill. This light has a pretty tight spot and a wide, but much dimmer spill and throws pretty well. I'd personally prefer a larger spot, but it was worth the price I paid ($17). The switch is a reverse clicky that doesn't allow momentary on, but does allow momentary off by partially depressing the switch when the light is already on. The lanyard attatchment is recessed in the tail, but the lanyard is thick, so it won't stand on it's tail. Removing the lanyard or replacing the lanyard with one that has thin strings at the attachment point would allow the light to stand on the tail cap. I think the light looks nice, but the head's a little big for most people to pocket carry. It doesn't come with a holster. It does feel good in my hand and the swith has nice positive feel and audible click and has a rubber cover over it. The head and tail cap have o ring seals, so the light appears to be at least weather resistant - I have no plans to dunk mine. The star assembly is screwed to the aluminum head with two screws and appears to have alot of contact for heat sinking. The head and tail cap threads appear to be machined pretty well with no signs of cross-threading when reattaching. I don't know about run times because It's mostly used for just short times and my wife and I are still on our first battery.
The two lights were pretty close in tint. One was pretty white and the other was also pretty white, but looked slightly grey when side by side with the other. One spot is almost perfectly round, the other is a little oval shaped. My wife has the one with the slightly oval shaped spot, so I've made no effort to investigate or resolve that issue because my wife hasn't noticed it and isn't concerned by it. She's liked having a light with a lithium battery in her car this winter.
If you go to Circuit City and want to try the light (they don't have demos at the store in my town), just ask the staff and they'll usually open one for you to try. They'd rather do that than have you buy it and return it.
Circuit City customer service was very good with me for the items I chose to return for various reasons.
