Just got a Surefire Millennium M6 Magnum tactical flashlight. This sucker will shine farther than my .308 rounds will carry. Takes six lithium batteries and comes with two bulbs - I believe that the lower power bulb could be rated as "sort of blinding, because your eyes are on fire" and the hot one is definitely in the category best described as: "vision pretty well screwed - might as well get a white cane and a guide dog, eyes are making a bubbling sound...". That's at twenty feet, even worse if you hold it close to your face and look into it. Built like a brick-shithouse this is an amazing light source. One slight concern is that it cost about the same as a good used rifle, and it eats batteries like Len's new Wolf is going to eat slow-burning powder. Also got their new LED flashlight which will give fifty or so hours, only uses two batteries and costs like three or four boxes of .308 match ammo. Interested to know if any of you guys have used Surefires on any hunting trips. They have a red filter that is supposed to show blood trails after dark - will be testing that in a month or two. I have used Maglights on many trips but these Surefires are much brighter and extremely well made.
