I assume that by halogen lamps in track lighting, you are referring to
low-voltage MR-16s? If so, following are some of their advantages.
1) Low voltage means safer, as well as reduced heat. Most of the heat of
the bulb is projected backwards, not toward the art object that you are
lighting. They are safer for the art.
2) MR-16 housings are suspended from a track, and thus the heat they produce
is dissipated quickly, not contained where it can build up to dangerous
levels.
3) MR-16 bulbs emit very little UV light, and the bulbs can be UV-filtered
if desired for virtually complete UV control. They are safer for the art.
4) MR-16 bulbs can have excellent color rendering properties (both CRI and
color temperature), producing more accurate viewing of the art.
5) MR-16 bulbs come in a variety of beam spread angles and wattages. This
allows control of the lighting from various distances, as well as the
ability to reduce light levels to the appropriate preservation specification
for the art object. Dimmers also can be used to further refine light
control. They are safer for the art.
These are a few thoughts off the top of my head. It seems to me that the
more you can emphasize the safety advantages to the priceless and
irreplaceable art, the stronger your case will be. Good luck!

Subject: [MUSEUM-L] Halogen lights in museums
Hello List
I work at a university museum. The university has decided that for fire
safety reasons halogen light bulbs are no longer allowed to be used in
university buildings. We, at the museum, are trying to get them to make an
exception for the museum. All of our track lighting uses halogen lamps, as
has every other place I have worked. Can anyone provide me with an
explanation as to why halogen lamps are "the industry standard"?
any help is very much appreciated.
thanks
