Therefor you can dimm the lights to whatever output you need.
And 400w is not too much for a square meter, it's around 37,4w per sft²!
If you want to go above 1100μMol/s/m² you can damage the leafes. This is called bleeching!
To give your plants the abillity to use such light densities they need a lot of nutrients and additional CO2.
It has been shown that light densities of 700-850μMol/s ppfd provide very good results when it comes to gram per watt.
If you increase your density, let's say from 1000 to 1500μMol/s you need 50% more energy but that will not lead to 50% more profit.
In fact, such intensities are very hard to handle and you should choose better a "safe" range!
As you can see on the 2nd. screenie, a plant with 500μMol/s and 30°c growth as fast as a plant getting 1500μMol/s at 35°C.
