My "new" '74 Duster- or why I need a project like a hole in the head

I see no way they can be THAT much better than the <$200 Truck-Lite 27270c.

The relevant technical standard (Federal/Canada Motor Vehicle Safety Standard 108) allows an enormous range of intensity at all of the controlled points and zones within the beam. The law doesn't require good headlamps, just legal ones, and a pathetic $6 sealed beam sloppily made on cruddy tooling in China (dim little spot of brownish light) is equally legal as a $6,000 cutting-edge Audi full-LED headlamp (giant, wide, bright beam patterns).

Headlamp price by itself isn't a reliable gauge for how good the headlamp will be; there is a lot of expensive junk on the market (and a few real bargains here and there) but generally we don't get what we don't pay for.

That said, the Truck-Lite 27270C is a good headlamp. Not as good as the JW Speaker, but still a good headlamp.
