Well it's about that time for me to start this journal. I will be testing my QB light ( @robincnn , @Stephenj37826 )in one 3x3 tent, and my (4) AutoCob's ( @Big smo ) in the other 3x3 tent. In EACH tent will be (2) Feminized Sweet Black Angel plants. All plants used for this comparison run are clones taken off of the same mother, and all are in 5 gallon SIP's using the same exact soil. Everything is the same between the two tents including fans, filters, timers, etc, the only variable here is the lights. I'm not a scientist running a lab here guys, doing the best I can with what I have available, and I am fortunate enough to be able to do this for you.
The QB light I am running was built by HLG and sent to me assembled. It's (2) of these boards: https://horticulturelightinggroup.com/collections/diy/products/qb288-quantum-board
They're mounted to a sheet of aluminum as the heat sink and are being pushed by a Meanwell HLG-320H-1400B driver.
The AutoCob's is (4) of the following in one of my 3x3's https://www.autoflower.net/forums/threads/autocob-55-watt-cob-led-grow-light.56994/
and (2) of them running Citizen 1812's in 6500K for my veg closet/nursery.

Strain for the run is Sweet Black Angel. I have already grown a couple of auto's under each of the lights to get a feel for them and get through whatever learning curve I may have had (and did) before comparing the lights. I would not have felt comfortable doing a comparison grow between two different products and not have used them before. The only issue with the QB light thus far for me (and not HLG's fault) is the original dimmer was busted in shipping, and I first had the QB full blast which is 320 watts at the plug on my kill-a-watt meter. I found this to be too much light for my space causing higher temps than needed/wanted and burnt/stunted my first plant under it. Once I contacted HLG they promptly sent me a new dimmer with wagos ready to go on the light, took me longer to take the light down and hang it again than replace the dimmer. I turned the light down to 250 watts at the wall and all is good since. The AutoCob's are pulling 244 watts at the plug and have given me no issues so far, only learning curve so far for me has been playing with optimal distance of light to canopy, despite how "soft' these run they will and can burn your plants if you get too close. I have also found this to vary from strain to strain. I have grown three different strains under both lights now and a fourth each under the COB and QB not in the other tent.
Right now my AutoCob tent is finishing up a couple of auto's and the (2) SBA's going in there are in the veg closet with the clones. The other (2) SBA were topped and put into the QB tent two days ago. I am letting them veg a little more to recover well from the topping and lolli popping they got before flipping the lights to 12/12.
AutoCob's in 3x3 are 3500K
AutoCob's in Veg Closet are 6500K
QB light is 3000K
Well enough rambling, here's a few pics, come along and let's see what happens in this grow

ive just replaced a 600hps with 600w of quantum and its the same temp
