Try it and you'll see.
i use the same, a GE 15 watt T8 18" fluorescent tube, "Daylight Deluxe" (they were 99 cents at a discount store)
I have mine about 4" above the board, and expose for 9-10 min
my boards are a bit too big for one light to handle, I'm watching for another to go on sale so I get good coverage without having to wait forever.
I'm using Philmore Datak positive resist boards, their instructions claim 60-90 sec for UV, 8 min for fluorescent and 10+ for incandescent ... they specificaly say not to use halogen, that a simple 100 watt soft-white incandescent bulb works best
