The same light is at a Chevron station near my home. It was metal halide but had a clear mercury lamp in it. It was dayburning for about a decade, until the station was remodeled and it was disconnected, though it still stands on the property.
These were used here too, but LED light are killing them out. Most of the canopies have a canopy version of this made by Cooper. I don't know if that's who makes these though.

I've also noticed LEDs at a couple places.
