Best LED Grow Lights 2020 | 3x3 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 3'x3' 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:

Are there any LED grow lights that have a flowering coverage area of 3'x3' that aren't on this list but you think should be? Are there any LED grow lights on this list that you think shouldn't be?

do you plan on only including lights you have personal experience with or are you reviewing strictly by the numbers? i'd love to see the california light works included on the list . i think most people are looking for the most bang for their buck & the cali light works seem very affordable

@shaw076 I consider all LED grow lights on the market. I've had my hands on a few of them but it's mostly by the numbers. Although California Lightworks LED grow lights do a nice job growing plants (I've grown with the SolarSystem 1100), they do not disclose efficiency in umol/j, or PAR in PPF. It's rumored that their efficiency is poor (around the efficiency of HPS or less). I can't add them to any of my lists this year due to that lack of information.
