heat off the diodes yes, but still producing the same amount of heat.

Aqua Man, what do you think of the Korona PAR app? Not having any reference, I’ve got idea if it’s great or a POS. Would be interested in anyone has compared it to their meter.

It’s not logic a watt produces 3.41 btus. You can’t change this. 600 watt hps or 600 led produces the same heat.

Shit, they’ve already make TV’s and vans out of weed. Saw it on TV a couple weeks ago - some guy named Marin and his buddy Donny (or Tommy, something like that, can’t remember all the details).

Its a learning cure for sure. With HID you know right away if the light is too close. Led you dont know until you damage the plant. That's my experience so far. Also having to switch back to HPS when it gets cold like now. Its either use an extra 150w light and stay warm or use a 1000w space heater to stay warm

But the heater is only on for 1/19 of the time and you can have more control over the temps.

@greenscholar
I 100% disagree. Maybe I don't understand your argument but some LEDs are double as efficient as HPS. Even of the same diode, running 10 diodes/watt produces less heat than 5 diodes/watt.

I had to read this a few times until the light came on in my brain. LEDs at 600 real watts is the same as HPS at 600 real watts?

This is the equation I found for calculating BTUs from wattage


BTU/h = (V * I) * 3.412


Where:
V = Volts
I = Amperes (Amps or Current)

Need to measure then the amperage of the LEDs and volts to figure it out. I think.

My bad, I misread it. I thought you were referring to heat.

Edit: I'm all over the place. You are referring to heat.

I do not have a mechanical engineering degree, but I do know that HPS puts off substantially more heat per watt than LED.

@greenscholar was referring to heat. I believe green was saying heat output is the same because it's the same wattage. Somehow I think it depends on the system and amp draw from the wall

not if they are the same wattage.
