Have been increasingly tempted by upgrading a great old 4 cell -but the drop-in cost and the need to invest more funds into non alkaline batteries (and another potential pathway to support $$$ w new toys…!) and related costs have just prevented me so far.
For the time being, picking up the old (and good) zenon lamps that I collected and still use a little bit will be enough.
Not tired of not having to buy those pricey, short lived CR123 batteries - kind of miss some of those powerful little lights though.
