Before we begin id like to thank Cammie from HGL & Stephen from HLG for giving me/ us this oppertunity. Takes balls fir sure. Those of you who don't know, HydroGrowLed is back. Cammi has been Making Waves with a shocking display of light give aways to growers whom will mostly provide side by side documented grows vs. the TopDawg of RIU, voted by the community. Whom of course is no other then our very own, well known QuantumBoard Creator himself, drumrole pls..... @Stephenj37826 & @robincnn. Proprietors of HLG.
So, there's so much to say about how like HGL is a founder of led grow lights over a decade ago breaking gpw's that we have a tough time with today. I remember believeing from memory that these are Not just Claims.
HLG, stepped up light distribution & electrical efficiency of their fixtures with the QB platform. Forcing many competitors to follow suit & creating a Monster QB trend. There are many who vouche for these boards & very nice grows to back them up. They have recently started to enhance their white spectrum using 630's & 660's as well as a higher K Temp., making a sweet full cycle grow light.
HLG uses a white phosphor based led as their Horticultural Lighting Solution, Whereas HGL uses Red/Green/Blue tech. Creating a spectrum specifically designed by the owner (Cammi) using a mathematical equation based on the many Nasa studies, Chlorophyll absorption charts & one in particular on tomatoes. Research Theory further backed up by A Plants absorption chart that appears pretty accurate & I think can be proven. Showing how much of each nm the plant uses & a ton of stuff she could explain better.
So we'll start with the HGL as HLG is awaiting Patent approval on their Trinity model.
Short on time for intro but they'll be plenty more to follow.
HGL recommended & provided x4 of their 84x models (150w) 1'x1' panels using their 3x special lenses to cover a 4x4.
Only RGB is used in these lights.
Here's what my 4x4 would approx look like based on HGL's many par Charts & a 2' hanging height which seams to be the height to accomplish the 4x4 coverage.
My spacing will prob be a lil further tho. Like 8" edge to edge.
Not bad coverage at all but for them its more about spectrum. Being the key to heavy yields & plant health. HGL says this light quality is far more important then quantity/spread, or electrical system efficiency.
Came shipped fast, like real fast & was well packed with protective Foam & extra corners built onto the box. (I tore off)
This Package to cover a 4x4 is small & easy on shippingI'd imagine .
12"x12" Panels
Lens array
Diodes are set deep in an Edison housing w/ 105• x3 Penetrator series lenses 
Screened fans to prevent debris from entering the unit. 
33.5" height disperses exactly a 33.5" , 90• footprint. 
Lens array Spectral diode distribution 
HLG Trinity Data/Info soon to follow.
Any questions?

Am running both sides at 475w to keep it equal. Its just such a waste of light on the QB side.
I deducted 20w for the Passive design of the HGL panels to give even light to wattage distribution. Each side has approx 455 w of light being emitted.
Just takes a day to dial all this in as ANY OF YOU WHO ACTUALLY GROW KNOW.
Its real easy for an NG to think they can boss a grower around, especially when all they think they know is what they read on a university study or what some NewB grower tells them.
Like DLI for instance. My primary lighting has been rated the highest DLI emitting grow light out of the several Anova tested & did full side by sides. It won on every aspect of the competition. So, im pretty familiar with what a plant looks like after having a hard day if maxed DLI hrs before plants under different lighting.
I know that a sad plant 4hrs after lights on is a direct indication the light is to close.
I raised it 6" & Low&behold, they are happy again.
When a person picks me to do their grow, they usually know i will do right by them.
However in this case. I feel that HGL has been attacked by so many for so long that they now have serious trust issues.
One thing i hope to accomplish here is to solve that problem for them. By seeing the work i put in & how badly i try to follow each n every recommendation.
The work & materials to revamp the veg room & set everything at exact equal distances would've costed a grower around $1000 to hire a professional last min. At least. Nevermind taking 2 days off work to do so. There's another 600.
Going out of my way to reacquire the MQ-500 To inform growers & prospective clients as much as possible on the fixtures outputs as they companies are both so Very Transparent for nothing other then our bennifit. Making them the best comp to do buss. with. I mean who wants to do buss with a comp that wont inform you about their fixtures in a real life setting when given the oppertunity?
I hope this helps & satisfies everybody.
Im not really sure who it is exactly thats dissatisfied as there has been allot of new accounts popping up. But whomever you are @MR.T or whatever/whomever i highly suggest you address me before anyone else.

Well, apparently things have gone a step further in the behind the scenes drama end of things & i will now be running all x4 , 84x lights in veg at a power draw of 567w
Tall plants are 21" & short plants in front are currently 24", working down. 
This will allow both sides a square footprint overall rather then matching ppf like i originally wanted to do, or like matching wattage which seemed like the next best thing . Now both lights are on full power covering a 4x4 as designed to. Guess we get full power veg guy n gals. This autta be interesting as well as expensive. Ha, oh what's another 100 to show the community the truth right?! Im Sure it won't stop there.
HLG TRINITY full Power Scottti, still 32" .

I still think matching wattage at equal distance will give a more reliable result as we are trying to see which light is best out of the box. Just my 2 cents but matching ppfd will give an advantage to hgl as it has more red and blue. Still i’m happy to see this side by side is happening.

HGL , x4, 84x Par readings at 23" utilizing 475w from the wall, around edges of plants centered between lights that are spaced 9" & 8" apart edge-edge. 
Center of all 4 , 84x's with the 2 back ones being raised 2.5" higher then the front 2 in order to achieve 21" off the taller 2 plants in the back. Readings were taken at approx 23" .
HLG Trinity Proto Par readings @ 32", 525w draw, far edges of the 5'3" x 4'3" veg area:
Center reading:
Any Questions?

Looks like ill be pushing the plants to obtain the recommended heights on the HGL side which will in turn even out the par readings.
They just started getting happy at the distances they are but will lower them all to 18" now.

All 4 lights set to exactly 18"off plants now. Equalized the plants to the floor so all lights are hung at an equal level. Same distance from the ceiling, creating one big panel. This should even out the readings for each side.
Heres the edges aprox 18" down & 6" off the walls on either side. Remember, im using my EyeChrometer after using the tape to gain several refference points. So its not exact .
Heres the Center:
And here is directly above each plant, 18". 
Pretty even now.

So, both companies have aprox 6-800 oooohmols ova each competing plant.
2 strains each but are both also vegging 2 more sets of doubles. Mmmnnhh, i wonder what they'll be going up against???, on my other thread of course.

Is hlg at 18” also?

18" down 6" off wall for hlg?

Amare Shill
Hlgs were measured right close to the walls.
Hell No guys. These are 2 totally different animals. Right now they are both at the manufactures recommended height, which happens to be pretty even par readings.
-The HGL'S are @ 18" w/ lenses
-The HLG is @ 32" w/o lenses
Guess that solves that old debate easily enough.

You're saying u believe the RGB spectrum is prob better then the hlg enhanced white?

HB2 whats the ball park price of each these panels to cover a 4 x 4 ?

New growth on HGL side seems to be purpling up. No hate, only observation.

i am curious the light cost value difference between the two...this is important to know

Looks like the HGL plants are being stressed a little more, I am only going by the pics since I'm not there in person. Are you noticing the same ?

I'm new around here OP so I hope you don't mind what I think is constructive criticism.
I think the value of an experiment like this lies in how the result data can benefit growers in making informed decisions.
As a grower what interests me most is the quality of the medicine I harvest and how much it costs. As much as I like learning all about light quality, spectrums and efficiency. In the end if a light will produce more dry bud per dollar spent (Assuming equal quality) this is what will drive my decision most.
For this reason I suggest you treat each light as if you would be trying to achieve maximum yield/cost ratio. plants should be optimally positioned in both sides to achieve this, I think trying to balance PAR or PPFD is hindering this comparison because in a real-world situation a grower using these lights will not be doing that. If you are handicapping one of the lights in any way the final results will be of less use to the grower, IMHO because the results won't reflect real-world usage.
Perhaps you can disregard the price of the actual fixtures and just look at running costs as those will closer reflect long time usage, and prices for specific units can change. IMO what needs to be looked at is balancing power usage (fans and whatnot included) because this is what makes up the bottom line.
Again I hope you don't take this the wrong way, I'm putting my hat down to you anyway because I think what you are doing is great and very appreciated. We (I hope) are all here to learn and you are making it possible.
