Well Paul I was planning on getting a TK75 in the next few weeks but I maybe buying a plane so I have to conserve money. Instead I believe I may get an EA8 as I am already set up for AAs and it will cost me about 120 less for the EA8 and Eneloops. On that note, what do you believe the max distance is for the TK41? (its close enough to the specs of the EA8 to be a good comparison) I would like to be able to get between 300-400 yards and because my EA4 will light up 200, I would think the EA8 could easily do that. I really didn't need the capabilities of the TK75 anyways but I figured if I was going to get a new light, why not get one of the top dogs. Thanks for all your help and answers to my questions.
