What kind of power does that thing draw?

I don't know the exact numbers, but it is in the multi-KW range. But
it's "efficient" with switchers regulated to supply just the exact
amount of forward drop required by each LED grouping.

Do you also have a constant current in the design, or do you just supply
"exactly the right voltage"?

I was actually thinking about this, is there such a thing as a switching
constant-current source, rather than a switching voltage source?
Wouldn't that be pretty efficient?
