Just a quick note: While I happen to love LED flashlights myself(I don't own a single incandescent flashlight anymore, and havn't for several years) you should know that LEDs are still not as good for very high power applications. The brightest easily available ones are the 5 watt luxeon stars. For small flashlights, LEDs are superior in every way; but for large ones LEDs are not always as bright. Halogen incandescents, for example, as seen in high performance flashlights(e.g. the surefire line) are rather brighter. On the other hand, battery life is much better, the beam looks much better and smoother, and(this last one is often important to owners of large Maglites) you don't have to worry about breaking your bulb if you forget which is the blindin' end and which is the beatin' end.
