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.
