sounds like you dont need a flashlight, you need a spot light! go to
www.huntsmart.com and get a coon hunting light. fits on a belt, a ton of options up to a 18 volt HID, and most come with a barell clip to attach the head lamp light to the barell, you can also get red lenses for them. even better is the accesory spot light, i can still hold mine and the gun at the same time, its a more focused beam, but very very long distance. Cajun also makes good lights, they are a little more pricey tho. there is another company but i cant think of their name off the top of my head.
