It seems none of you understand how the sun works, LOL!
She's 92,960,000miles away, do you really think the one foot more or less makes a difference?
Incidentally, sunlight is mostly diffuse, even in the brightest skies, the diffusity is ~5%. Atmosphere, dust, clouds, water, reflections, ... all this makes sunlight more or less diffuse.
Why do you think the sky is blue?
Because light is reflected by the ocean(waves acts like millions of mirrors) and than it's again reflected by the outer atmosphere and bouce back on the earth. Do you still believe sun rays are hitting plants only in one direction?
The reason why a 1m high hanging lamp has better penetration like a 0.5m high hanging is the light is more diffuse. With increasing distance you get more and more reflections, which makes the light more diffuse, thus it can penetrate deeper. It has nothing to do with ISL or the sun or omnidirectional or directional, when we talk about better penetration everything is about diffusivity.

However, I do not see that you really need to hang a strip-based lamp higher.
The hundreds of diodes from a strip based lamp provide for a diffusivity that a point light source can not offer. So I think that a 12" high hanging strip based lamp has better penetration like a 1000w lamp, no matter how high it hangs.
Simple setup (without measuring equipment): hang a COB over one big plant and see from the side how much shadows you can see (take a picture), then hang a strip over the same plant and compare how much shadows are still visible.
You can clearly see a difference using only your naked eye.
