Howdy all, I have been looking around the "internets" for a new flashlight to replace my long (last week) lost Surefire E1B. I have noticed Surefire places the word tactical only on lights ~80+ lumens. Now, this would mean a E1L wouldn't be "tactical"? so I can be promised that I would be able to blind someone with night vision? or is it all just marketing hype and anything ~40 lumens or so could do the trick?
