Another good UI is head fully tight for full power, head half a turn loose for low.
Thats pretty much how my 2 cell EDC Surefire L4 Lumamax is set for which Ive been using for almost a decade. A 5/200 lumen low/high with momentary push and twist settings which is just about perfect for searching and working uses. Same they dont make these anymore.
