Not too many of these older M-250R2s here. The early M-250R2s had more character. I think the deep style glass lens and semi-recessed refractor rim played a role in that.

I hope they replace only the photocell and not the fixture when they service this next.

Agreed. Here they'll ust replace the PC on a dayburning merc but with HPS it gets a new lamp and PC.

Ah I didn't notice that this was actually an R2. Around what time period was this generation?

Typically for dayburning mercs, they'll replace the photocell and sometimes the lamp.

This version is beterrn 1985 and 1989.

In 1989 sometime they changed the door design so that the rear of the lens wasn't recessed. the top housing stayed the same as far as I know. Then in 1992 to 1993 they had a different M-250R2 with a different top housing and a different door. Then in 1993 they may have changed the top housing again (not sure, but after 1993 the top housing design has remained the same since). In 1993 they reverted back to the 1989-1992 door but with no GE logo on the door. Then around 2002 or somewhere around that they put the GE logo back on. When they put the logo back on, it was oriented the same way as the NEMA tag. From 1992 and prior, the GE logo was "upside-down" on the door of all their lights.
