That great in a sealed and static environment. But the way IR is absorbed by, (and thus the degree to which it heats) biomass changes the variables greatly. The ability to cool more easily with less extraction due to the way the heat is radiated, combined with the ability to run the room warmer due to a much smaller temperature variance between ambient and canopy means that I actually use less real world energy to maintain my grow.
And what equivalence would you need in HID? The same?
Run them hot, you reduce life expectancy. A tricky thing to balance depending on costs involved.
being ignored? did i not say it would produce more photons than a less efficient lamp?
No thats awhole nuther argument that depends on what chip, bulb, power supply, etc., etc..
But that light will ultimately be converted back into heat.
Yes this is a very good and well worded explaination, thanks @Uncle Reefer
The size of the heat sink will not really affect your room ,it is more about the LED's operational temp
Yep there we go, clear case of goal post shifting.
No, it is valid as if you produce more light per watt then you gain that by creating less heat. The heat per watt cannot be constant irrespective of the type of light as otherwise you create more energy, light plus heat, than you consume and that is what is impossible.
Why?
Light is potential radiant heat
No, it isn't
Yes exactly, that's what I said a dozen or so posts ago.
Wrong, as a space heater does not convert most of that 1kW into light.
because thats the way thermo dynamics work. a photon contains energy. when it strikes something, part of that energy is absorbed by the object it is striking, and released as heat
Yes it is. Just take your ignorance somewhere else
And this is where we part ways in opinion
if you give it enough time, the interior of the closets WILL be the same temperature. i promise. you can trust me, i don't know you well enough to lie to you.
