A significant reason not to use incandescent bulbs in your storage area is
heat. Especially if the volume of the storage space is small and/or the
lights will be left on for more than a few minutes, the incandescent bulbs
can contribute significantly to raising the temperature/lowering the RH in
a sealed storage environment.  Also, you might want to look at different
fluorescent tubes. Our library is now fitted with an energy-saving T-8
size tube that happens to have lower UV output than regular tubes. The
light is yellower than regular tubes, but that is not a problem in areas
where color perception is not critical.

One source for UV sleeves for fluorescent bulbs is:
