I get that he sells both. My friend also owns a hydro store, and loves selling LEDs because it's a better profit margin and he knows they will be back to buy a differant led and then on and on. He literally laughs about it.
Just my perspective after watching the video, like I said, it's well put together, but the order he did things, way he said things, and the things tested gives me the impression it was never truly ment to be a fair test.
I never really see temps 10f over ambient, that's just crazy to me. As you see in my data a few posts up

If you follow his channel you would know that he doesn't like led's.

My mate runs a hydro store to. He has no LED's.

Maybe your being overly critical?

K guess that was just my impression then. Anyways still think this video is a little suspicious. Hes def overstating the heat generated, I never see numbers like that. Everyone I know swears by moving more air, and its proven over an over to work. And when a few parts come into question, it all comes into question.

Just saw your edit asking if I'm being overly critical. I mean, of course I'm being critical that's what I do with everything. You'll also see I gave credit where credit was due. I call all that together being fair. I said what I liked and what I didn't like. I took the time to watch every second of it instead of watching a min or 2 then judging.

I can give him more credit tho if it needs evened up more. I like that hood insulator idea. I like that he used blue tape. And like I said at the opening of my post, the video was well put together. I think it's fair to take issue with the negatives I pointed out though. Especially the part about the extraction fans.

Dude a lightbulb is literally a filament surrounded by gas encased in glass. A heater is a filament. In both cases electricity is used to heat the filament. What about that is wrong. Point it out.

HID(MH and HPS)bulbs do not have filaments. They have arc tubes. Your bro science does not apply here.

lol ok dude. So we are changing the name in a bigger application but it still is what it is.
A 1000 watt hps makes the same amount of heat as a 1000 watt room heater and it's basic structure is nearly identical so split hairs all you want it doesn't change anything

if they both use 1000 watts and both produce the same heat. Where does the light energy the HID bulb produces come from? Be careful now, the LOTCE is in play here. And it's a law that cannot be broken.
Everyone get ready to be wowed by bro science.

You dont seem to understand and that's ok. Theres likely no way I can convince you, and you'll probably continue saying bro science to anything.
BUT most of us here know a watt is a watt and it doesn't matter what being powered, it's the power itself that generates the heat. Something like 3.4 btu per watt.

An here some real bro science, I haven't had to use a heater to heat my home for nearly 8 years because my hps does the same thing, for the same cost, and I get to grow plants with it. Bruh. Its like.... totes a heater my dude.

Physics say different.

Light is electromagnetic radiation. Heat is a form of energy transfer. Light will produce heat when absorbed, heat can in turn produce light (see Black body). But the two are different.

I may be wrong here. Only speculating, I'm not a physicist. Just throwing a spanner in the works here.
But in thermal dynamics, doesn't heat = energy?
Doesn't something have to reach a certain kelvin to produce light???
Like a red hot piece of metal? (or the sun)
Its all light isn't it?
The right kelvin temperature still needs to be reached to produce a specific wavelength does it not?

:peace:

Watts and heat are pretty much the same thing.
All the light turns to heat in any closed system. What doesn't is about 2-4% used for photosynthesis, that's the leaf efficiency under sunlight, its less under HPS because the spectrum is not equal to the sun. It should be more in LED because there isn't energy wasted on a huge potion of the spectrum been in the IR range. Not that im saying IR has no purpose in plant growth.

But the bottom line is all watts are heat. 600w hps or LED or electric heater, it all heats the space roughly the same.
