Pretty sure he meant that good LED's are the most effcient light which means you get the least heat for the job.
Best light on the market ?

Let me explain how an LED(COB) works. The heat is pulled from the COBs into the heatsink and dispersed above the fixture. There is less heat between the canopy and the light.
LEDs do create heat. It is expelled differently than say an HPS. LEDs have less IR(heat) than HPS.
But they do create heat.
The key is a good heatsimk to keep those COBs cool which will make them last for years and years at no cost to the grower except about a 15% increase in yield over HPS. They pay for themselves after the first grow.
You can pull 2 zips a square foot.

Almost 0 heat with led compare to HPS.
I grow in the attic and in the winter I am forced to add incandescent 60w light to increase the temp. (on the side not even facing the plants)
With HPS in tent I always have problem of heat and need strong ventilation. I stopped working with HPS once my ballast start to make bzzzzzzzz sound. Since than I m trying led and only problem I have is too cold in the winter

Isn't a light bulb a "warm" or "cool" spectrum(3000k and 6000k). I would point it at the plants. lol
Can you redirect the heat from the the light back down into the growing area?. 4" fan should do it.
Might help some or get you a red heat lamp. (IR) like HPS puts out. But then you are back to square 1. lol

I add the old crap 60w incandescent light from 40 years ago just to warm the tent, it's such a crap output that I let it be in the side so it won't disturb the other lights.
Above 60w you can't find those lights anymore, it's illegal

I still have some of them.
A chicken heat lamp would work great for what you need.

I use a "Little Buddy" propane heater when it is just way too cold out. and I made a CO2 generator to increase CO2 when I want to shoot it to 1400ppms. My ladies get a constant dose of CO2. because I grow organic, my grow area stays about 1000 ppms of CO2 all the time from the microbes farting.

I was thinking about buying the old paraffin lamp to add heat and CO2, on the way to the shop I got sacred I might burn the attic so Instead I got fire extinguisher (the one you hang upside down)
Teach me not to go shopping too high.
I might skip grow between Nov-Feb and that's it

Who said they don’t put off heat?

Ya bro you and other led freaks need to stop wet dreaming your crap all over these boards.
The real growers do not act like this whether led or hid, i only serve to remind you led mofos of what pricks you have been here for a few years now.
As to what the best lights are... i know but would i ever discuss the realities of science spectrum and photons with demi members that have been here spreading their own personally independently elected broscience like they the real growers here pffft......!

This is going to seem like im trolling you on this thread but you and the other led freaks are talking way too much broscience.....
The sun puts out near half its light as IR so no freaking idea what bs your quoting there!
Your describing a very inefficient plant light led freak.
Heat is radiation, convection and conduction, you should wiki and learn this before even opening your mouth here, far too many of you pros seem to lack even a basic understanding of heat, why you struggle with hids and run to leds thinking they give bigger yeilds, what amateurs.....!
Such noobs, any real science or just the same old copy and paste led rubbish, like this site could be so much better if you lot just shut up and let some real growers do the hard stuff you cant

That’s amazing that your CO2 levels are where they are due to microbes. It’s honestly the first time I’ve heard this claim.

Why would it help to switch to IR?

So there is a difference in the amount of heat (btu’s), watt for watt, between IR and visible spectrums? Is there any quantified studies re increased yields (15%).

Another led grower will just take over and carry on the hype on this thread, they dont want to do science or talk they just want to go on about how supreme they and their diodes are.
Their spectrum is also a lot weaker than hps but we cant say this science as it upsets their ppfd bullshite they have preached here so hard

DE1000 with a Phillips bulb is the best bang for your buck.
I pay 385 for a unit & $115 for the bulb.
To come close to this in cobs, was $1800.

You also said you don’t want to deal with heat . DE are a little on the warm side

Because I was asking for an education on how COB LEDs work???
I wasn't. I was responding to a false claim that you don't have to worry about heat with LEDs.

Heat management is still something that needs to be handled. Your claim was that heat wasn't even a consideration when it comes to LEDs. My Citizen/Cree room will get warm af if I turned off the exhaust and intake fans.
