I am running 600w in a 4x4.
So with this logic perhaps 400w in a 3x3 but i ran a 400w hps in this space so no more efficient than hps?

315W. Rule of thumb is 35W per sq.ft.

This was a marshydro FCE3000 over a 3x3 footprint. 300w LED.
this was using a screen and only my second full room scrog so still better to come yet. (Been growing for 13 years) and this was my first LED grow too was using a 400w HPS over this prior to switching to LED.
happy I’m using 100w less and appear to be pulling the same if not more out of the LED.
Honestly you want to look at your area, how many plants you want to cover then figure out how much PAR you want to deliver to the plants. Watts don't mean anything if the efficiency of your drivers and diodes are crap, that just means you are wasting power. How many plants are you planning to grow in the 3x3, are using C02? what else would be in the set up? PAR numbers are the true measure of energy you want on the plants to drive photosynthesis.
