Here's a couple of graphs:

They all look pretty narrowbanded. Maybe with a colourcorrection filter you
could move some of the peaks around a bit, but then you would have to know
which lamps they use exactly. And it will only change how the lamp looks
like, and not change the look of the environment. Unless of course you
would put a gel on the lamps.
