I’m not saying anything, scientific data suggest that. Either way if hlg is fine with same umol values its fine by me. I think it provides an advantage to hgl.

Sorta in the middle only - will be great to see how this plays out when hlg clearly has the superior distribution

The HGL set of 4 , 84x / 575w = $1800 I'm told.
The HLG Trinity / 525w = cost TBD.
Yeah, thats why i usually dont go this close in early veg. Hoping it doesn't get to bad. I'm using mag almost every feed.
Gotta maintain a good distance & be around 450-500 umol at this stage to prevent that with led it seams to get healthiest, happiest plants with led on my experience.

Oh i’m perfectly fine with it i can interpret the outcome of the test knowing that some aspects of the test have provided an advantage to one fixture. And if the other fixture was modular and can reach the desired light print at 18” the hlg test group would be getting a much higher ppfd reading under same wattage.
It just complicates stuff a bit.

Let the guy do 'his' test FFS..................................but on another note $1800 to light a 4x4............................

Results of to much high intensity lighting via following recommendations.
See the purple/red vein? Thats an indication of a serious problem about to occur if i do not nurse her back immediately. FYI this happened from starting at 12" & moving up to 18" via instructions/rules/demands from HGL. If i do not follow all these "recomendations" then i am told i will have to return the lights after all my hard work. 
IME this issue is a real PITA as its very hard to reverse. I usually use the MH DaylightBlue in weak intensity to cure this problem but do not have that luxury here.
So, i backed the lights up quite a bit for recovery. Wish HGL & Me luck pls. Ultimately I'm the only one who suffers if these plants Croak.

noun: recommendation; plural noun: recommendations
HLG on the other hand recommends 30-36" at any wattage that makes the plants happy. So Basically, Stephen recommends i do what's best for my plants.
Here it shows the beginnings of light stress that took place the 2 days i had the Trinity on full blast (525w). 8 hrs of 32" was enough for me to see i had to raise the fixture. Raising to 4' did not help so after 2 days i lowered the wattage & dropped it to 36". They should quickly heal up now & are already showing signs of improvement .
Here you can see the purp vein started to take place but i backed off & they should get better now. 
The Smaller plant used to show the leaves in these photos are the big Cola plant (HDF x ST) that i had high hopes for as being the competing plant if only one fits. Shame.

Today all plants were amended with a light top-dressing of 1/4 - 1/2 cup EWC depending on the pot size. Then covered up with a lil CoCo.

What did you drop the trinity wattage to?
And is the HGL still at 18in?

Now i’m glad i turned the offer down
It would be a big hassle to ship the lights back from overseas.

Most of us all know what Oooohhmols we're supposed to veg at with these size plants.
Here, i bought this just to show HGL & anyone else questioning me.
8" down 
That is the Standard in veg intensity for the first mo., while they're in 6"-9" potts. Then i move up to stronger light once transplanted into 3's. Before led i used T-5 for the first mo. & MH for the second. Now i use 100w strip lights to replace 440w T-5's for the first mo. Then switch to whatever led i want cuz only then are they ready for 600+ umol.
Kind've mad rn cuz that damage is hard to reverse & HLG's plants now have the upper hand even know they were hurt to, i was able to dim it sooner then i could find a proper hanging hieght for the 84x's, which appears to be 36" now that the plants need recovery.
Well, if anything maybe now she'll recomend the 32-36" they should be at during this stage in the game. I understand she wants to win but with led often less is more.
Here's the center at around 36". Notice how much higher it is then the 18" previous center reading? Its higher then u der the lights themselves. This shows uniformity which you need distance to achieve.
Heres the 2 comp plants. 
Here's where i set the Trinity just to get the plants back to happy. 36", 273w. I'm using the Trinity as recommended by the manufacturer. 30-36" at the dimmed to wherever the plants like it best. Sounds good to me. Thnx fir making it easy Hlg. Due to super HE, i am able to achieve similiar Par #'s using 273w & thanks to the diameter of the board i can still accomplish this at 36" w/o lenses.
Center
These next 2 are the comp plants that were in the center receiving 7-800 umol for 2 days & were not very happy with me at all. 
Heres the far corner
Ill have to ease the 4 comp plants back into stronger light & they now require an urgent foliar feed.
If i had just vegged my way both sides would be bigger, healthier & not have to be repaired which will set them back from their full potential unfortunately. But we'll get past it, no worries because From here on out i am doing what is best for my plants. Losing just one of these babies exceeds the Retail value on the lights anyways so if i have to return them then so be it. At least we as a community got to see the truth. That's worth more then all the lights i have.

Oh & for those who may be wondering what it takes to flower here you go .
This plant was purple vein damaged & complete purple stalked from high intensity led vegging right before flower & the only light that it would accept was the MH. So i grew this plant on low & medium settings on the ballast.
Rn its on medium or around 750w. Plant lived & even turned a decent haul.
While most other plants got between 700-1200. 
But most plants Can Not take these kind've #'s unless they are in optimal condition going in. The only way that is going to happen is if i veg thdm the way i know they need to be vegged.

Looks like you fade ur plants like I do.
Seems to be purpling in the majority of the pics. No expert but maybe they want some N or P.

They want less light intensity is all.
Very aware of this situation.
If i let it continue we will all say it looks like you need this n & that p but not that k & oh, more mag, don't forget your cal ect ect... and all it is light density

Thank you @hybridway2
I suspected the light would be too intense at the heights she recommended. I could tell it kinda set her off when I showed I use cobs at 0-6 in. She has a lot to learn about physicis and biology. These are things you already know and by her arrogance she shot herself in the foot. She shoulda let you grow to the plants instead of trying to bend the will of the plant. Props to @Stephenj37826 and hlg for recognising the variables.
