But generally HPS lamps with wattage higher than 1000W were extremely rare, compared to MH lamps which were available up to 3500W, and for the entertainment industry even 18,000W.

With Sylvania's BriteArc set of lamps, they use quartz and are medium-arc. Quartz is fine with most halides but is not compatible with sodium-mercury amalgam. Here is a 1500W lamp, even higher than 1100W: https://www.1000bulbs.com/product/89389/SUN-901692.html
