What is the ideal brightness for a flashlight for spotlighting on foot in tropical rainforests? I’ve been using my Fenix TK75 at its medium setting (600 lumens), and I am concerned that it is too bright and is scaring mammals away. While a dimmer light would be just as good for detecting eyeshine, it would be less effective for spotting animals that are not looking in my direction (or don’t have bright eyes). I am most interested in larger mammals, rather than small rodents. I’m going to a site with relatively high hunting pressure next week, so everything should be pretty skittish.
Would a red light be better?
