Just what wfo204 said, If you can't see it, You can't shoot it. With that being said there are a lot of lights on the market ranging from $50-$350.00 or more depending on your options. Use what you can afford and if you get hooked like a lot of us have, you can always upgrade to bigger and better. As far as shooting at night it changes a lot when trying to first of all, find what your trying to shoot in your scope and how far away comes into play. There are so many variables, add weather and it can make it tough. I have a property that allows me to shoot at night and what I get is some small red plastic reflectors 3-4 inches in size on stakes and I place them all around the field at varying distances within my comfortable shooting distance and I will try to shoot them out, kinda simulates what you are seeing with your light when your shining for critters, it will help you gauge what distance you can see out to with your current light. Plus give you some practice at hitting your target at different distances.
