As my eyes get older, I handle low light less and less successfully. That's just part of the aging process. I don't think turning on artificial lights is a good idea, only my personal opinion. I feel we need to shoot in the natural light. One reason is that we need to shoot in the conditions we will experience in the woods. Another reason is that you need to realize when it is too dark to shoot well. Granted, some will need to shoot under lights in order to shoot at all due to other priorities; however, I do not think it is a viable low light training aid. Simply shoot until natural light runs out. Others will disagree, which is fine, as these are thoughts that apply to me alone.
