SOIL LED - Brand, Coverage, Intensity

I have 4 Yager plants in the seedling stage. Within 5 weeks, with my 2x2x4 tent, things will NOT be managed. Things will get ridiculous and I won't be able to apply LST no matter how I manipulate it. So, I will be ordering a 48x48x80" tent soon but my next absolute need is a new LED light (or multiple depending on coverage). I need recommendations for:

Wattage
Coverage (how far the light stretches/coveres)
Brand.

LED users only, or those with prior experience, please give me some ideas. My new tent will by 4ft by 4ft so coverage is the biggest priority next to intensity. Will I need multiple LEDs or is there one out there with enough coverage & intensity to cover all bullet points?
 
I'm happy with my two Platinum LED P4-XML2s in two 4x4 tents. They are an older-style panel light with fans inside and all that. Newer spread-out designs may be better, especially when it comes to even coverage and energy efficiency.
 
The only light I have used, that said Spider Farmer SF 4000 in a 5x5. Had very good results with it. Good price, efficient.
 
A 4x4 has 16 sq ft of canopy.
That is approximately 1.5 sq meters.
You can achieve really nice flowering with an average ppfd of 750 umoles/sq m.
That means you will need a light capable of generating about 1100 umoles ppf.(750x1.5)
Most fixtures using top-tier leds like Samsung lm301 generate at least 2 umoles/watt, so I suggest at least 500 actual watts.

I have run leds for the past 5 years, starting with a system I built for my main grow along with a few older 'blurple' fixtures I have retro-fitted with more efficient led strips.
Although shipping is a mess now, I have also purchased a QB-style 480 watt panel fixture that I use n my 4x4 pheno tent
It's an Alibaba-Meiju lm301h3500k/660nm https://www.alibaba.com/product-deta...a85221e26Cwe7V
it does a great job overall, but for maximum yield, I would look at a bar-style fixture.

I am very happy with my spider farmer sf1000. It’s only for a 2x2, but they make many sizes. I’ve read a lot of good reviews on them, and had a successful first grow with it!

I also picked up a cyber Monday deal on a viparspectra p1000 (same 2x2 foot print). I hear a lot about that brand on gwe. I plan on doing a photo run next, where I’ll grow 2 of the same strain side by side under these two different lights. I’ll be sure to post my findings. (And ill be purchasing a second of the “winner”)
 
I run an HLG 360 Elite in the 3x3 auto tent. I like it. Before that it was an HLG 100 in a 2.5x2 tent. I also have a Grow-it-LED 600 watt that I haven't used yet. The Hlg's grow some good weed. The bigger light in a 4x4 tent should be good as well.
