Super effective green light - Viridian V100 Long Range LED Illuminating Flashlight, 200 Yard Range

have has this unit about three weeks. Works great, still on original batteries and have maybe 3-4 hours of use. I use it mainly for hog hunting over feeders and for that it is very very effective up to about 100 yards providing bright clarity and excellent field of vision. It can either be a free standing, or attached to a rail if you are moving around. I have used it both ways when hunting at night. Excellent product and if I ever lost it would purchase another one immediately.
