This is what I'm currently thinking

would 130W of PC be less than or equivalent to 48W of T5HO? If 130W is too much, they have a 65W version.. which fixture would put me in the medium-high light range?

I would be going for 2 T5NO Coralife fixtures if they still made them...

I have DIY CO2 with EI fertilizing, and am aiming for a heavily planted tank. I do have the option of raising the lights up to about 12" above the tank. Thanks!
would be why high lighting is out for you

get a 2x14w T5NO fixture instead (you would be low-med)
