Unfortunately I think it's way more complicated than this. The wikipedia article mentions 3 different types of sodium lighting: LPSV, HPSV & SON. Of course much modern lighting will be LED too. SK53 (talk)
Moreover, the usual acronym for high-pressure sodium lamps seems to be HPS, not HPSV. And we prefer our tags in lowercase, so it would be "hps". (IMHO, the word "vapor" is redundant in the context of gas-discharge lights.) Anyway, since "sodium" is already used here, I'm tagging some lights as "sodium" right now.

Naively, I'd tag the ones with very orange light as sodium myself. 09:51, 30 July 2018 (UTC)
