I work in total darkness out in the cold for at least 4 months of the year. the ONLY light that I have came across that will not chew through batteries and produce a good useable beam is the pelican 2960. I can run it for 2 weeks without issues where my princeton tec/petzal/etc have more bells and whitsles.....but I need to pack batteries . it has no red light, no fluff.....best light I have used though as far as always works and last for a long time.
