Not necessarily, lights and watts play part of the role but environment as a whole e.g lights,humidity, temps, nutes, ppms, ph, genetics ect determines your yield.
But looks like your really smashing your grow dude nice and frosty and only gonna get fatter!
Your lights powerful enough for what you have but if you do want to be able to have your lights closer to penetrate deeper into the canopy maybe look at an air cooled shade for your next grow.
I use 3 of them with a 6inch inlet and a 8inch exhaust and have no trouble with temps ect really worth the extra money.
Good luck bro
