Cobs simply stands for chips on boards and the chips are leds but nothing like standard leds. Cobs can contain different K values or even UV to make up the matrix but standard cobs used are all pretty standardized with the cobs using all the same K value chips. Their commercial application is warehouse lighting and even streetlight lighting.
I know that are all LED, but there are many different types and forms of light emitting diodes.

I’m honestly not sure

What do you mean about them being run so soft?

Isn’t there a 1000+ diodes being run at <1W?
I have no idea how many actual diodes there are on each "LM" series chip, but I don't think there are anywhere near that many. If I'm not mistaken, COB chips have a couple hundred diodes per chip so I would assume the "LM" series have a much smaller amount of diodes.

My light has no where near that many diodes.
. Cobs def interest me

Running them soft is reducing the dial from 10 to say 5 to 7. By running them soft it is a lot easier on the drivers and the boards and you can achieve a greater light spread by spreading the watts over more area.
And they might last forever.
Cobs are my favorite style of LED ... lol.
And veros and citis both work great. Veros can be run at 100 watts and citi 1212s max out at around 60.

Point source is spread out. Soft is better when you have many, it isnt diminishing raw photons, just less heat on the physical materials.
Strips just seemed to fit tents the best, thats why I think they took off. A51 lighting did the exact same thing years ago and imho is what Johnson lighting aka HLG copied. Nothing ground breaking, it had already been done, lol.

another thing is height. A lot of these vertical farming lights (strip Leds) are marketed towards tent growers. That with the better light spread and better penetration from what i understand.

I’m really not family with strips. Are they kind of like more spread out boards then?

Each strip has 70-110 diodes depending on manufacturer. There is usually 6 -8 strips on a fixture. I love my cobs but that light spread is hard to beat.
Im not sure what the actual differences are in terms of product quality. I no led technology keeps getting better and better so i just took strips as another advancement in the tech. not that 1 light is better than the next but that each light has its own particular use case.

Soooo. Question to Cob and/or QB people. I have 4 HLG 65 watt boards which is giving me 260 watts of led. I have 2 x Timber Grow light daisies pumping out 100 each. So I'm running 460 watts in a 3x3 which is plenty. However , here's the rub... the cobs have way more light penetration but do you think it would make a huge difference just to go with 4 x cobs for a more even light spread and penetration.
I mean the QBs are awesome but need to be alot closer to the plants to get maximum par.
Does it justify another $275 upgrade or not
