What’s the spectrum? I wonder if they’d be good for growing desert plants indoors as well.

Incandescent. So, full spectrum. We have a similar one in the office, probably 5,000 watts.
You’d be much better off with metal halide for growing though. Just as much light, much lower wattage, much longer life.

" If the radiance of a thousand suns were to burst forth at once in the sky, that would be like the splendour of the Mighty One."
That said, anyone know what the niche for 20kw incandescent bulbs is? Yes, none of the competitors can match that nice, close-to-ideal-black-body behavior; but it’s at the bottom of the barrel on efficiency and at 20kw, that starts to really count.
Is its massive IR output helpful for letting our reptilian overlords see clearly in their secret underground bases?

I used to work in film lighting and I have no idea what the use case for this is in the 21st century. Any single source that size would generally be an HMI, and if you needed to balance it with tungsten sources you’d throw gels on one or the other. We still used 9- and 12-light tungsten and iirc even up to 10K for a single lamp… I think maybe they were cheaper to rent, not needing finicky ballasts? @Donald_Petersen might be able to shed some more light on this.
