Right lumens for a 125 gal.

Ok this is my first post , i'm building a 125 with dirt for plants, being reading that watts per gallons rule no longer applies, now days is about lumens, so what will be a good lumen for my 125? Or should I look for something else?
Thx

6500K bulbs are the ones you'll need. Don't buy anything with the Lumens label. They are a waste.

Lumens only applies to the human eye, it has nothing to do with plants. You want to light an aquarium with PAR. Have a look here.

How many watts if I may ask? And how big is the fixture?
