I was looking at the Battery Junction website earlier. Are all single 18650 lights considered "tactical lights" and all 4 x 18650 lights considered "searchlights"? I already have a couple of Klarus lights, but I am considering a 4 x 18650 "thrower". The Battery Junction website seems to be leading me towards the ThruNite TN42. The Black Friday price of $135.96 might work for me. What 18650 batteries should I used for the ThruNite TN42? Can I get a better 4 x 18650 light with more throw for that price anywhere?
