Flourescent tubes (350 nm range)

I am building an exposure unit for alternative processes and was
wondering if there is anyone out there who has had experience with
fluorescent tubes made by Voltarc or Phillips (is anybody out there -
it's been awfully quite lately?). Specifically I am interested in any
tubes that might reduce my exposure times from that obtained by using
a standard "BL" tube. The reason I raise this question is because I
understand that ICP (International Center of Photography - NYC) has
installed Voltarcs in their new darkrooms and they are said to reduce
exposure times; I have yet to speak with anyone who has done a direct
comparison. The Phillips bulbs, I believe Phillips calls them
"Actinics" draw 40 W. as opposed to the usual 20 W. (they require a
special ballast); again I have not spoken to anyone who has actual
used them.

Anybody out there?
