As for Exposure, after, what, 20yrs years of pissing about with increasingly expensive alternatives that invariably had multiple compromises or failure points and very poor after care, finally bought a Six Pack earlier this year (outlet + members discount made it A LOT more reasonable). it is brilliant in every respect. Job jobbed.
However, IMHO wide beam spread on a helmet light is a waste, i sold my Diablo because of that. I don’t need a dim wide beam on my head, I need a tight spot for looking round corners etc. Four4th scorch is not as great in many ways, but the beam is more useful.
