That one we'd like to do at home, if I could get my hands on an LPS lamp, there's a lot of wrongly marked bulbs out there, afaict.

  Just look in a growing shop. Isn't that what they use?

    No, they used HPS. Although now replaced by LED.

      Ah, fair enough. Doesn't seem so hard to find a legit one though. Searching for Philips SOX gets me a lot of results for example.
