No, it generates 33% more heat
HPS vs. LED Grow Lights — Which is Better for Growing Weed?

17,000 btu a/c inside the 4x8, can barley keep up in hot summer days.
This panel gets hot, no less then a 600 hps bulb.
Most of the game in growing is Heat management, some genetics will take heat better then others, but as a rule heat will demolish your results, and demolish them the fastest where it is most present - the canopy.

"Prove me otherwise"? LOL. You want me to disprove something which you haven't shown any evdence to support yourself? Get the fuck outta here.
Your 800w LED will "push" 682 more BTU's than your 600w HPS will. The difference is how they will "push" that heat. The LED will be primatly emitting convective heat, whereas the HPS will be primarily radiant heat (graphically observable via that huge IR spike at 820nm). Because of these facts of physica, the HID will heat up the leaf surface temp at the top of the canopy much more than it will innercanopy. LED on the other hand will heat the leaves of the canopy more evenly (and less efficiently), compared to HPS, due to it's lack of IR radiation.

BS. Put your hand on the panel for as long as you can without burining yourself. Now grap the lit HPS bulb for the same amount of time. Then go to the hospitle to be treated for burns. You are just spouting nonesense at this point (you really have been all along).

I always get drawn into these debates lol, I can never tell if it’s someone who is trolling with an agenda (which I’ve came across as in the past) or someone legitimately trying to further the cause and debate with their peers.
I didn’t even know this was a Mars thread or I wud of never posted haha (NAUGHTY MARS!!! Haha lying to us 10 years ago about the blurples!!!)
It’s actually nice to see Mars making some decent entry line fixtures these days. It’s crazy in terms of user friendliness for the newbie, how much better hps was than blurple, and how much better full spec white lights these days are compared to hps.
I have to agree with @snakedope though on this. Imagine the future we’re about to realise with led!
Hid plateaued decades ago really, only 400v de, and advancements in ceramic tubes pushed the boat after that.
Led on the other hand is far from mature tech, there’s still so much room for improvement, and especially with the work being done in phosphor luminescence, it’s staggering to even wonder where this could go.
We’re probably now looking at some of the first lights that will be used to grow plants to sustain life in space. The agentix liquid cooled lighting certainly has a lot of potential when I think about heat recovery and how we may utilize that.

I dont care how they push it, stop talking to me in ON PAPER terms and start talking about real life
IN real life, my tent and canopy is heated under the panel just like a 600w will heat it, no one told you to grab the bulb
you are too clingy on words, dont understand the full meaning of them.
I said at the beginning that ONLY IF U MANAGE THE HEAT
So stop talking to me about how much heat a HPS bulb put out as it irrelevant to a good grower who knows how to manage that heat !!
If you dont know, you will have less trichomes on your tops, this is a fact, no need fancy words to explain why heat destroys trichomes, heat from anything ! from IR heat to bad growers with Cool as snow led fixtures that push less heat in comparison but heat the the whole tent very much like any other light source at this high wattage
Once you hit that over the line heat point, there is no going back, you lost your frost and the game, and it dosent matter HPS or LED.
They are certainly not better, not for flowering MJ, not for now.
They will grow plants, as all lights will even the smallest Lm light, They will also grow trichomes, but have no "Kick" when it comes to producing them massively or in anyway compared to HID, both science and reality support this claim.
But again, im talking about today, the future looks bright for this tech in terms of power and spectrum, even more then CMH
I just personally hate LEDs because i know they are very toxic to DNA and our Eyes, thats why they are pushing them all over the world and in any segment of private life or business.
I wish that LED makers do realize in the near future that one cant go without the other, a perfect spectrum cant go without a matching intensity
A perfect trichome production cant go without both, not just one.
This situation portrays our actual nature, the sun, perfect spectrum with very high intensity which is what we all should strive for.

Actucally that's not true. I've measured leaf surface temps under LED and also under various types of HID (including HPS). The leaf surface temp is always a few degrees higher under HID than it is under LED. The reason for this is obvious, it's due to the IR heat which is thrown by HID lighting. I mean really, this is basic stuff.

I didn't suggest that was due to genetics, you misread me. I suggested that increased frost in general is related to genetics and overall health of the plant.

800w in a 4x8 is your issue. No wonder you can’t grow donkey dicks covered in frost like the rest of us.
2 X 800w, each cover 4 X 4, please read before posting.

Which fixtures exactly?

..and heat management should be treated differently under HID vs LED light sources.
Bro thats exectly what you said, but i wont hold you for it as its not a barking match, and i really dont care what every person says
Increased Frost is genetic to an extant, i do agree on that.
Agreed.
This is the panel:
Rated at 110K Lm (Total Ofcourse)
2.8 Umol (sigh)
PPFD Avg at 10 Inch: 900
90 angle lenses
Meanwell drivers, all philips diodes

I can see how you misread me, however if you go back an look at that post, you will see that I used paragraphical punctuation to seperate those two statements.

Makes sense why you don't like led.
My 250 watt puts out more ppfd than your 800watt.
Least it has a good driver.
