How about another option?  You could use two 22.5" high lumen biax bulbs
(see p. 942 of the '96 Grainger catalog - they're about $15 apiece).  These
come in 40 Watt and 50 Watt flavors, with the 50 Watt bulbs having shorter
lifetimes, and fewer color temperature options.  A ballast which lights 2
of these bulbs goes for ~$35 (p. 995 of the '96 Grainger catalog).

To mount the bulbs horizontally, you have to purchase a "2G11" type base,
which Grainger does not carry.  To get some, call Edwin Gaynor Company, at
203-378-5545 (in CT).  They will sell them to you direct.

Good Luck,
