Whoop! Exciting acquisition!
Halides are the old standby. Fighting for dominance by LEDs these days, but many old timers swear by them. You can pretty much grow anything with metal halides plus T5s. That was my setup years ago. I had the T5s come on around 4pm, halides on at 6pm, halides off at 12am, T5s off at 2am (ensured the tank was on full display during the rare late house party).
Problem with both T5 and halides is the bulbs need replacing every six months or so...otherwise the spectrum starts to drift towards the algae-friendly zone.
I didn't follow your comment about glass tops...but generally a bad idea with any light. Condensation will obscure the light, and you might even get algae growing on the glass. Or, are you asking if the MH lights should have covers? If so, yes...MH bulbs are really sensitive (like, don't even get fingerprints on them or they could blow out) so make sure your fixtures have covers.
