Not a concern: we'd just build a walled tub of sorts, put in enough de-

Actually I was thinking the tub would be built out of plexi. That way
you could get the same level of light from all around as opposed to just
from the top (hence the reflective surfaced for the container). That way
you may get more even UV illumination on all the surfaces especially in
the nooks and crannies. Just a thought though as it may not improve or
make things worse.
Why get so elaborate? Last year while I was looking at building an indoor
UV setup, I was considering a simple wooden frame to support four 24" T8
blacklight lamps about a foot or so above my bench. I haven't yet gone
much further than looking at various lamps/fixtures/ballasts since I'm
still not sure de-yellowing many of my computers would be worth the
effort.
