UPDATE: Here is the final list https://www.mrgrowit.com/post/best-led-grow-lights-2020-4x4-coverage-area I'm working on writing articles for the best LED grow lights here in 2020. I will have different articles for the different size coverage areas. The LED grow lights listed here have a flowering coverage area of 4'x4' and are for a full-cycle grow - from seedling through flowering. This list is complete fixtures only; DIY LED grow lights or lights that require assembly are not included. For a LED grow light to make this list, I factor in: PAR output, efficiency, spectrum, light spread, diodes, drivers, and warranty. Below are the LED grow lights that I am considering putting into the article:
The grow lights are listed in no specific order. Click on the light to learn more about it:

Love my HLG-600 R-Spec, a bit of overkill but the results speak for themselves...
In regards to a 4x4 what are people's thought on 2 Mars Sp.3000. or Mars Fc4800?
Hey I purchased an enlite ceres 780 I have a 4x4 only c02 is an exhale bag I'm growing autos most are in veg I have a couple in flower the company said to hang it 6 to 8 inches for flower which I thought was really close and at 18 inches it has avg ppfd of 600 and that was even burning and yellowing some plants and even some leaf curl taco so I wanted to know I have a Dr meter and I know the lux can give me an idea what would you reccomend my autos lux be at the top of the plant? And what lux is a good in between if I still have a couple in veg? I notice you hang your lights a bit higher in your video and reccomended an avg of 18 inches but idk if that was in general or for your light?
