WOH Why did I not think of that. Two hose clamps. Genius :-)

I ordered one of those 4x18650 rechargeable magic shine 900lumen Knockoffs for $47. states 1200lumens (yeah right) but testes to 850-900 lumens ie more than enough.

for now a little low watt led light till it arrives. works surprisingly well for a little flash light. those twin flash lights look amazing. is that ATES or picture exposure enhanced?
