DONT KILL ME! I know this rule is very outdated. Im only looking for penetration and par at bottom of substrate. If I use 75 watt equivalent A19 bulbs would it be high light and would there be enough par? I would be using 12 bulbs on a 125 gallon if that matters. It will be high tech with co2, liquid ferts, and rooted ferts (im too tired to think of the name for that rn). Heres link.
