Check out outrigger outdoors website, they have some real good hunting lights.
I use my bloodhound blood tracking light every time I go hunting. It runs on 3 AAA batteries and can act as a flood light or a zoom in to shine over 100 yards. Has illumination mode and blood tracking mode depending on what you need to do. My good buddy has the red eye light and he really likes it but it runs off 12 volt battery. It's 10,000+ lumen and will certainly mess up your eyes if you look into it.
