a tricky one guys.i'm after a LONG range handheld spotlight.torches have advanced heaps but 12 volt are the same crap.i shoot with a fenix tk30(best rifle light ) and have a acebeam w30 coming but i'm after a handheld that can run continuously.looked at the weltool w4 but manufacturer says 10 minutes runtime.i also would like more flood than these two while still keeping the distance plus led and lep drop down due to heat.the great white led car spotlights are stunning but WEIGHT is crap.i'd prefer 12v but have plenty of 18650 and 21700 batteries if i have to go that way.any ideas? many thanks mike
