Thanks, thats what I was wondering about ,the N- 62 is what I am running , It is crazy strong I agree, but I have not seen the Beam of The TK-40 IN PERSON, and have seen the TK 45,and heard lots about the 40, The 12ZM is still pristine, I got it when I didnt know much about lights, and I am still a beginner really now. Still have the box and paper work too. Thanks
