You can do that, but it doesn't really buy you anything. Cannabis can only use a maximum of 10000 lumens in flower, if you give it 25000 it doesn't produce more yield. The only issue is does it penetrate further down into the canopy giving lower down buds closer to max lumens, but that is really a factor of fan leaves, etc...
