Lower Lumens/sq ft for smaller area??

I searched the board but I couldn't find the answer. Lets say x number of lumens per square foot is required for bud, would that number, x, decrease as the area of the grow room shrinks?

Example, a 10x10 grow room has an area of 100 and a perimeter of 40, a 5x5 grow room has an area of 25 and a perimeter 20. Wouldn't the the increased ratio of reflective wall space to the area of grow space reduce the lumens per square foot required in the 5x5 room?

Always go for the most light you can, doesn't matter if the room gets smaller, the more light the better the results.

U totally lost me as soon as I hit EXAMPLE. But anyway, to answer ur ? YES the amount of lumens and watts req'd could be cut in half from ur discription, which is basically one room half the size of another right? I believe the general 'rule' is 3000-5000 lumens per sq. foot, thus the light req'd for the square footage of the bigger room, should be roughly HALVE of that for a room HALF THAT SIZE. God that was confusing, think ima burn one.... yep

sorry, i'm not toked up so i'm not thinking clearly. Let me rephrase the question.

Is it conceivable that 125,000 lumens would be more effective in a 25 square foot room than 500,000 lumens in a 100 square foot room?

I realize that the lumens per square foot are exactly the same in both rooms.

it would be the same imo.
