These were led boards my brother turned in to. Individual cobs, as per his company innovation. Each little light is considered a cob now as the chip and optic dome has been added.

My point is there maybe a way to make it simple say this is cob that's led for battles, with simple pics, but if one really gets in to lights u can see similar components being used that may make one believe it something else. But from the top engineering guy at my brothers place is canna friendly and cool, now big company's cant decide to promote quantum boards or cobs as the new wave as they are both superior compared to past and present and where the lighting world is headed. But by may 2019 my brother will have a fully functional light system that mimics the sun and will rise and fall in his grow room. The lights power the track rollers by heat it's coolto watch it when he's got it going. I have lots of lights to build but boards are my first choice. As photos seen better in them , finishing a coblight fixture on Wednesday has 2 x 1750k in middle and 2 x 4700k on each end. @Mossy I wanna see a battle with autocobs against built cobs, I've done my own but need more inputs to say one is better than the other.

Ya but I have leds with chips on board theres variations of cobs and leds. I have cobs look like leds but nope style of con lenses and they stay lit after u shut it off for a few cause they are used in stadiums and I have leds that look like a cob I above pic but are leds on the market. I have Cobs yhat are 1/8 " squares up to 1" the actual lightpart is . Hope helps anyone.

Yes light definitions are blurry. So lets just keep it simple. The plant in the competition will be grown primarily (>50%) under COB lighting. COB chips typically have 9 or more diodes. COB chips also only have 1 circuit and 2 contacts, regardless of the number of the diodes.
