New mammoth fold series 800w or 600w

I want to purchase one of the new foldable lights from mammoth, but i do not know if 800w is overkill for a 4x4 tent?

Shouldn't need more than 600 watts of LED for a 4x4. 560 watts is really good if the LED is a quality one.

30 - 35 watts per sqft is a good rule of thumb for quality LED lighting.

The 800 watter is better suited to a 5x5 space.

Thank you
