I have a couple bought one on amazon and another at academy. I think they give sufficient light. I actually have 2 set up for one feeder from what I've seen they will give me enough light to positively ID a hog or coon and get a shot off, granted I'm only shooting from about 40-50 yards away. I will actually get my first chance this weekend to actually see it in action I set them up and left them for a week to see if the critters will get used to them. I'll try and get some pics of them in action and post em this weekend.
