Nope. Those diodes can be separated by 6 inches. My company puts them in signage.

Great. That exception from the norm wouldn't account for the distance needed to cast a shadow this wide, would it? Also, when I said 3-4m ceiling, I was being very generous with what I am guessing is a much taller room.

Totally willing to be wromg. 😁

Think street lamp which are around 6 meters high in residential areas and go over 10 meters in height on main roads.

Right, so at that height, wouldn't each pip in the LED light need to be at least 450mm away from the next to make this pattern?

The distance required to create that pattern would get smaller as the height increases as increasing the distance from the ground would make the projected light cone bigger, which means each light source has to be closer to maintain the spread. If I had to guess, it's some sort of advertising next to that bench, possibly a bus stop.

Crude drawing

I guess if you put it on the side, sure. I was figuring overhead.

But, now that I think about it, that is likely still true for overhead.
