I repeat all this occasionally to provide a reference for comparison to what I've had before, what I'll do later, and what others are running.
Tonight's occasion is the COB test done on the vertical plant that the owner concluded was inadequate to replace their trusty HPS lamps.
The original design, a pic of which is still on the thread, was a box with COBS on all four sides. 800W in this shape would seem to be a good match for a thouie hung vertically. It wouldn't need lenses because it's designed to throw light in all directions. I still think this design has possibilities, and
@legallyflying I suggest you try it again in this configuration. It would be a simple and low risk swap for a thousand watt HPS.
When the design was split into several component pieces, two things happened; one, it lost its ability to be compared directly to a thousand watt lamp anywhere, and two it had the original advantage of no lenses or reflectors turned into a disadvantage; there are fears of light lost because it's missing the plant entirely? Not sure if that's the case in your setup.
If the pieces were assembled into a flat array, they could once again bring their advantage of distributed light intensity fruitfully to bear. Maybe if all the cobs were aimed at a wall of buds it would also do better? Your panels are flat, just like mine... dunno, spitballing.
