Does LEDs really yield the same as their "HPS equivalent"

This is a 120 Watt deformable 4 paddle LED at work.
I assure you it is the brightest interior light I have ever encountered.
Check ebay. I found a new 150 Watt deformable. Remember all you do is screw these in to a socket.

Here is my Malawi mother plant growing like no tomorrow under the 120 Watt deformable LED.
This is a dream come true folks. Fucking laser beams!!!!!

Here is my young mother Malawi. She is quite content and growing very nicely.
These fucking lights are insane.

Those pics aren't a great sales pitch for that light. Got any better pics, maybe some with buds in the pic would be good.

I do not give a shit if you do not like them. I am simply pointing out that they are the BEST thing I have encountered in 50 years of growing.

That's nice, but until we some pics of plants with nice buds growing under them, no one's gonna buy what you're shilling.

Just think if you were using LEDs that were twice as efficient as those lights, like those of use growing with QBs are. Your mind might be blown.
 
For me, LED's just give harder buds with more trichomes. I've just done the experiment. HPS buds are lighter for the same size, sure. But, there is not money saving in electricity, as you need the same wattage than with HPS (or MH).
The only problem i see with Led's is that they don't give enough heat, it can be an issue in winter for instance.
In my grow i put MH for the stretching after 12/12 flip, 2 weeks, and i put the led's tonight till the harvest.
But i'm talking about good quality led's, no burple shit

I'm repeating myself, but this shit is worth repeating. I didn't really get it a year ago, but it's simple:

Photons drive photosynthesis. The more photons you produce the more yield potential there is for you to realize. Micromoles (umol/ppf) is a measurement of photons. A mole is 6.02214076×10^23 photons and a micromole is a millionth of it. The most important give away here being that umol is a defined number of photons.

Photosynthesis is a chemical process in which the energy of a photon is used to remove an electron from h2o and then using than electron to produce atp (a chemical energy packet) which is used to make carbohydrates out of carbon dioxide. We can calculate the number of photons needed to produce one gram of plant matter. Let me repeat that: We can calculate the number of photons needed to produce one gram of plant matter.

There is no magic. Photons drive photosynthesis. The more (par) photons you produce the more yield potential there is.

^oh and brightness is nothing. Brightness is something humans experience and plants don't have human vision so they don't care about how bright we think something is. Humans are very sensitive to green light and the same ammount of green photons will appear much, much brighter than say 660nm red. For the same kind of lights you can use brightness as a reference point, but for different spectrums it is not a viable way to compare growing power (comparing the brightness of a 3500k led to another is ok. Comparing it to 5000k is fairly close, but comparing it to hps is not and comparing to 660nm monos is definitely not ok).

Lumen is brightness and umol/ppf is number of photons.

A mind is a terrible thing to waste.

LMFAO, I found this pic in your shared folder (https://dvdzrus49.imgbb.com/), is this your great grow?..

That is a maturing Zamaldelica. Next to it is a Malawi. The cola on the left is ABOUT 22 INCHES LONG. That is part of the great grow. I also have L. A. Amnesia and Jack Herrer.
