You said at one point that at most you could only get 70 watts out of the ballast when the max (with 0.88 ballast factor included) would be 112 watts. Just out of curiousity, if you wired up two T-8's in series and did your test at 3x and 4x OD do you think you could get the full output from the ballast?

It's a fine line between fishing and standing on the shore looking like an idiot.
That IS an aquascape, it's titled "The Vacant Lot".
