No those are cobs just not the largest ones 3070/3590. They make much smaller cobs.
That being said it seems everyone wants a high bay to be a grow light. A good purpose built cob led grow light is the best idea. There are great options out there.
Oh, okay, thanks for clearing that up. However, if you look at this
video you'll see that the light is only at high enough PAR where the beams of the two cobs overlap. That tells me that you need to focus two cobs on the same spot at about 16-18" down so they form one bright round area of decent intensity. A single cob's beam is not suficiently intense. It would be less than 500 PAR, I'm guessing, since the overlapped area is about 980.
You would also need to grow in a round area to match the beam shape. Overlapping a bunch of beams would create more bright spots rather than a uniform square of light. Though actually since the LEDs in the cobs are arranged in a square shape, as far as I know, I guess it's the round lens that makes the beam round. Maybe the plain cobs would make a square beam. Somebody should make a square lens, if that's possible.
