Your posts are so filled with misunderstanding and just plain wrong, that it would be way too much work to do... You should do the work yourself if you are interested in knowing what is true.
I took the time and put forward YOUR numbers and maths, not mine, its the LED panels numbers.
Everyone can add or subtract whatever he wants, some people will use common sense some just like to think they know it all no matter how skewed their theory is, and thats ok bro dont take it too personal
These are their numbers, YOU chose to add, i chose to subtract, to each his own.
Furthermore, you would think that by now the LED manufactures (as to support their claims) would have put lower and lower wattage diodes on their panels and add more qty of them cuz they scaled the tech down (like CPUs which only gets smaller not bigger) cuz hey, PAR and spectrum is everything right ? who cares about intensity
NOPE lol they just keep making them bigger and bigger cuz they know without intensity their diodes are pointless unless set up in array of panels which also dosent help because all your doing is making 300 suns with 250 Lm each oppose to a 150K sun in the same height, that is LUDACRIS to even compare, but hey im not a scientist.

Now, sure a 4 250W or even 4 150W will do a better job at any given rate but the heat will be a big problem
So i give LEDs my thanks for making my Veg very nice and efficient in terms of plant size and wattage for sqf, also no way near the heat of HID, which is a big plus as i veg for 24 hours and if i needed to tackle the heat problem as well i would put a lot of $$$ in my electric bill
to sum it up, LED for veg, HPS or MH or CMH for flower depending on what your target is (full sun spectrum or full intensity) most of the time a good mix of both HPS and CMH will give you the best results, not in terms of power and heat but in terms of quality product.

You are free to continue being clueless. I'd suggest you don't, but it's your choice. If you do wish educate yourself, you could start by figuring out why 100k lux hps is quite a bit less light than 100k lux of white led. That's easy.I took the time and put forward YOUR numbers and maths, not mine, its the LED panels numbers.

Reality says otherwise, sorry i have to believe reality.
Like i said, you chose to call your panel a 100k lux of white led, i call it a panel with 250 lm lux X 300
is my definition of these led panels are wrong ? are they not 288 or 300 or no matter how much diodes on a panel ? hmm maybe im missing something here

Yes.
So let me get this straight, OPTIC and OSRAM and HLG is telling people to put their 600+ watt panels at 5-7 inch distance because they are super high intensity 100 lux monsters ? Do you even crunch the numbers ? do you even find logic in those claims ? sorry i dont.
if i had a high intensity light, i would gladly put it 40 inch from my canopy and will deal with less heat WIN WIN but sorry again reality is skewing your paradigm haha
Its not a secret or even debate. they clearly state that their lights are low intensity lights meant to be used 5 inch from canopy at best
So if your not gonna pour the time and info on this thread to show us "common folks" then why do you even comment ? lol
Stil im waiting for 1 reply from you that counter what i have said, non so far
But its ok bro im not arguing about nothing lol i just subtract and you added, good for us
Still reality is the most importent thing, still you cant deny or argue that we live in a HPS world
The sun is magnetic current and it lights the sky when it touches nobel gases (just like HID) so ill take my bet on the sun, still open to opinions on the subject as i told, i found that led is very good for veg, which is the most $$$ consuming process for me atleast.

I personally can't put any of my leds closer than 12-16" from the canopy without getting some form of light stress, burn or bleaching. I usually as a rule stay 18" away from the canopy but I also use Cobs. This is my first year running a QB and they are the Samsung LM301H diodes. I've noticed I can move it a tad closer than my Cobs, but not by much. I like Led because I don't have to replace my bulbs every cpl grows. I've seen the low watt diodes - old Led tech. Amazon panels and not impressive. The new tech is tho especially the Samsung Evo diodes. I still love my Cobs tho. Having less heat is nice too, with HID I was around 92-97°, with over 1200 true watts of Led the highest it gets is 81° but average is 73-77°.

Any member will confirm I know less than average about the technical jargon around lighting its boring, if you take all the spectrum graphs and technical bs out of the equation the end product tells all.
i have a 70 day veg time even the lame ass 250 Lm led diodes are enough cuz they spread over my whole 4 X 4
I'm picturing tall and lanky.

I also feel that you are talking about the efficiency of LED to HPS, and you are right, they are more efficient, but are still rated 300 Lm for each !
So like i said before, when they make a diode that puts out more Lm then HPS (i dont care at which wattage as long as its lower then the HPS for their claims to be true) then we can start comparing, you are trying to compare high intensity lights (HPS) to low intensity lights, sorry not gonna work,
LED it good for spread, nothing more.
I do however can understand that in theory, given the right diode and the right wattage and in enough time (because LED is more efficient) we will see tech companys that are able to reach this kind of tech will beat HPS, at the moment they give 300 Lm, am i wrong ? is there a super LED light that i missed ?
I am truly sorry, but it wont help you to stick 1000 diodes on a panel, its still a 300 Lm "Monster" that needs to be 5 inch from canopy in order to have any effect on MED production, not VEG production ! this is basic math which applies to any light source, but not to LEDs for some reason lol
My plants are not tall and lanky, well comparing to HPS grows i had they are, now its under a 800w led not dimmed so full power from the get go and they stretched, also not too much, the WC more then the Blue Cheese, i think its mostly genetics, but i also see when you under power your light source it will also have an effect when it comes to stretching but not as much as genetics
here is the Spyder led, look at the height that they recommend

What's your opinion about cob led. Cree, citizen & Vero? I run 12 cobs in my tent currently. 8 of those cobs are running at 50 watt. The cree cobs run at 100 watt per cob. Light.
Also i would like to note that im talking about MED production only, im in day 63 now of flower and frost & thc is nothing like HPS or MH, just isnt there.
You can see it clearly that the LEDs even my 800w monster cant seem to "Stress" or in other words, dont have the intensity to make the same high power MEDs that HPS so easy does, again comparing to HPS, im not saying it wont at all cuz hey i got 16 plants and they got some thc and frost but nothing like my other HPS grows, and its not just me, i see these "Buds" for lack of better term of people and i feel like they are missing the whole point, they grow massive trees that are beautiful and healthy but where is the MED in all of this ?? if u grow for fiber or oil i can relate to this kinda low intensity grows but im in it for the Potency brooo

Yeah, cobs are smaller -> narrower light beam -> must be run higher up. If you make the light emitting surface smaller you have to move it further from the plants. Otherwise you just light a part of the canopy. If you make the emitting surface larger you have to move it closer (unless you have a way to avoid spilling the light).
Haha i never claimed i have the biggest, most resinous weeds lol
You really think i dont want to put pics of my grow so i can show u and make you proud of me ? i see people here putting pics and getting feedback and precious info that i cant get because of that, its not i like this situation, i love this site but never register, just read every little thing from 2008+ as im 35 by now, i went through a lot of reading and grow so much that i felt like not signing in is a waste of good ideas and words, either way i love people here and all the knowledge and ideas i get from here
Be sure i want to post my pics as bad as i want to smoke whats in them haha just i dont feel it justify the risk im exposing myself into
Today all we have is smart phones and taking pics is risky with GPS locations time stamps and all that shit, where are the days of the digital cam haha i miss those days badly, but i will put pics eventually when i will get over my paranoia shit

How to disable a smart phone's geotagging feature
Pictures taken with a GPS-enabled device can give up your location, as the recent arrest of John McAfee showed. But turning off the function is not hard.

Can't post pics.. but have you heard of a thing called vpn & multi-hop vpn? You can literally mask yourself online & the tech has been there for over a decade.
Sorry but I call bs , post pics of it or it didn't happen.
It's really easy and simple to use a ip block mask and a vpn. You can literally be in 3 different nations and hop every 5 min. I'm the type that if there is no proof I automatically assume a troll keyboard warrior at work. You can get vpn's for free, it's that simple.
