I use a flashlight this time of year almost daily as it is quite common for my wife, myself and my dog to take a walk in the dark on an empty country road. I always take two lights; Attitude for primary and the UK 4AA AS2 incandescent to spot light items of interest. Since I use an incandescent when I want something REALLY BRIGHT, my favorite LEDs are not especially bright; just bright enough.
