you grow with the led 6 inch for the plants and hid 2-3 feetThat video is a joke, the DE fixture is tested at 3 feet and the LED is tested at 12 inches or less. If you put that light meter 12 inches from the DE fixture it will read much higher than the LED ever would.
That's not an accurate test then if you measure at different distances. Also those guys got paid by those LED makers to give a favorable review.you grow with the led 6 inch for the plants and hid 2-3 feet
the test was done how it is grown for the whole grow....

Guess you don't understand the law of the inverse square then.lol u are smoking to much
nope i dontGuess you don't understand the law of the inverse square then.
Not trying to get you, just trying to educate and help, that's what this forum is suppose to be fornope i dont
u got me forsure tho i will have to google it
dont mind me i forget you cant read my tone in text lmaoNot trying to get you, just trying to educate and help, that's what this forum is suppose to be for
That's completely wrong, how do you figure 600w of energy doesn't dissipate 600w of energy? Somehow you think it's cut in half by some magical forces because it's an LED?Not true. The wattage is current x forward voltage. The electrical watts are dissipated by the LED in light and heat.
A half way decent LED 600W fixture will dissipate no more than 300W in heat.
That's not how it works but good try, you might want to read that thread i posted it will help you.If you call light magic.
Thermal Dynamics is about heat transfer. Not electricity and not light.
We are talking about electricity being converted to light.
Do you understand photons carry energy?
And you know radiometric flux is measured in watts?
Where does the light's photon watts come from?
The electricity that is not converted to light is dissipated in the form of heat.
The ratio of light watts to wall watts is the efficacy.
An Olsen SSL red LED Radiant Efficiency: typ. 56%
Forward Voltage typ. = 2.15V
Test Current 350 mA
Wattage at test current = 2.15V x .350A = 0.7525 W
Maximum Light output at test current, Radiant Power = 0.56 Watts
Of the 0.7525 watts of electricity the radiant flux =0.56 w
0.7525w - 0.560w = 0.1925w of heat or 74.6% efficacy
You can't even read the thread i posted before spouting off at the mouth, all the answers you are looking for are in that thread , read it completely before responding or my next move is to block you from further communications.That IS how it works no matter what the other post says. Where do the photons get their energy???? Answer that smart guy.
Ok idiot you cannot read what i sent you so let me make it easy for you
That's from the thread i posted you, now you are ignored because you couldn't read it and figured it out for yourself, i'm not here to argue.Because the light will also turn into heat eventually, and since that light stays in your room it becomes heat in your room.
Photosynthesis stores some energy inside the plant (doesn't become heat), but photosynthesis is rather inefficienct so you can safely ignore it.
So 1200W will always be 1200W.
Inverse square law is not as simple as it seems. Optics and reflectors are seldom factored in...Guess you don't understand the law of the inverse square then.
Ask yourself where those photon watts go? What happens to those photons that do not get used in photosynthesis?If you call light magic.

larf!Aside from light that is converted and used to build plant material, all the light eventually gets absorbed by everything in the room and becomes what....?
