I don't really know what's best to be honest. Some of the new LED units are
looking pretty good while many continue to use HID and full spectrum
fluorescents. For hot lights, Solux lamps are supposed to be very well
filtered at both ends of the spectrum but you'd need a lot of them to light
a large piece of art. Plastic sheeting used to filter U.V. is available
cheaply in large rolls so it's easy to use it over any light source, but
good IR filtration isn't so I use Schott glass IR filters behind the camera
lens. I think LED and wide spectrum fluorescent are much better choices than
quartz when it comes to IR, but as in the case with Solux which is
internally filtered, each lamp is different so it's hard to generalize
without comparing the manufacturer's data.

OK John, I'll bite - which type of studio lighting emits the least IR?
(LED?) But what about UV, isn't that more important to reduce at the light
source? And if so, what type of lights produce the least UV?

Does it help? The right place for filtering u.v. is at the light source.
Once the artwork is fluorescing from u.v. light you can't filter the
problem out at the camera. More IR filtration at the camera can help with
some art, especially if you're using hot lights on a subject having
colorants prone to metameric failure but it's still better to use lights
that emit less IR in the first place.

I must thank someone on this list that suggested purchasing the B+W 77mm
UV/IR Cut (486M) MRC Filter for issues I had with reproducing a
particular piece of original art. It was around June 15, 2012. I
purchased a B+W 67mm UV/IR Cut (486M) MRC Filter as well. These filters
are
always on the shooting lens.
I don't remember who it was. I have been asked who it was. If you are
out there, please respond.
Warm Regards,
David
