I am glad there is still some mention of the TK41.......I have the 800 lumen model,which was my first"real" flashlight...well, after my 6-Dcell Maglite,which I thought was the cat's arse back then! Just charged the batts last weekafter sitting a while. Lots more lights since that one which I bought new after joining here last year....Gotta stop buying!! Still love it!! Hot Brass
