Maybe that is the case with your average 4' fluoro. But my setup is all CFL spiral bulbs. I have a light meter and can tell you with out any doubt that the intensity is on a curve. Thats why I decided Stadium to begin with.
But even with intense light on the lower stadium parts, Bud growth was the most limited.
My fixture is 248W/18K Lumens(72L/W), Compared to HID I'm not at much of a loss(aside from localized intensity). Plus I have blue spectrum mixed in there.
I'm not trying to be a snot, But if light from a candle radiates in all directions spherically then light from my round bulbs must also radiate a sphere of intensity.
I agree that after arranging all my bulbs I had more of an oval of intensity. Maybe thats why it will work well for a flat??
