Watts per gallon is not a good measure of light intensity. It does not take into account depth. In case you weren't aware, the intensity of light follows the inverse square law, I=1/D2. And that's not D*2, that's D squared. The point is light drops off quickly the farther one is from the source.
What you have might work if your tank is 12" deep, but maybe not if it's 24".
One should be concerned with adequate par, say 150-500. If you don't have access to a par meter, that's when people start saying things like "would this acro live high up under my 4 bulb t5?"

I typically use a rough estimate of 2 x LEDwatts = MH/T5watts for a conversion to get a baseline sense of the lighting you are dealing with. Granted, this can vary greatly based on LED's, drivers, optics, etc etc.
I agree with above, but WPG can still give you ballpark IMO.
