That would be nice. I even discovered that I did that math wrong I actually have 179 watts of light, but eighty is in wide spectrum 4 foot tubes. Will that alter the calculation much?

179 w * 0.33 g/w ~ 59 g

How did you come up with this conversion rate?

Let x = conversion factor for 40w T12 wide spectrum fluorexcent tubes
(99 w * 0.33 g/w) + (80 w * x g/w) = 33 g + 80x g

Now all I need is a value for x

ANOTHER QUESTION

Should I replace my T 12's with T5's? Are they readily available? Do I need to change ballasts for these?
