Have you noticed any benefit to red, green or blue light? I mean is one of those colors strongly preferred over the others? Also, I can say that a 65 lumen spot light like a Surefire G2 is too bright for close, less than 20 foot work where you want to see the object clearly. Is 45 lumens ok? 25? 15? What is ideal for cooking and doing activities like gutting a deer?
