Compact shelving Fluorescent and incandescent lighting

We are building a new rare materials vault with compact shelving. We
could either use fluorescent lighting with UV filters and then light
would be evenly diffused throughout the aisles -- or use incandescent
lighting, which would probably be better for the inks, papers, and
bindings in the long run but which would leave dark spots in the aisles
unless we spaced the bulbs about every 18 inches (the Las Vegas effect).
Scylla or Charybdis? Does anyone have any suggestions? Which should we
go with?

Also, are foot-candles still the standard by which reading light levels
are measured?

Thanks for your input.
Virtually yours,
