Technically, the results will not be the same.

You will have 4 'less concentrated' lights as opposed to 1 very concentratred light.

Depends on how many you grow.

So technically you will have 4 lights that take up 4 sq. ft. of space versus 1 light that takes up 1 sq. ft. of space.

Given the choice however, I would personally opt for the 4 lights.

I can light the bitch up from four different directions.

HAPPY LIGHTING
