I am certain that you could build a unit to expose a negative this
size (10" X 90") much more efficiently by using 8' (96") tubes. Six
or eight tubes should cover the area, and one could get this by
placing side by side three or four of the commercial two-tube units.
Eight foot tubes are widely used commercially and relatively
inexpensive.

I figure it would take me about 1/5 of the time to build such a unit
as the one suggested by Jeffrey. And a lot less money as well.
