Can't stop laughing. REALLY dumpster wars hahahaha

the more you research the more you will find out, you can either pay an exorbant amount of money for an LED panel, well around $1500+ to compare with an 1000w HPS, OR! you can build one for about $500-$600 cob. sooo you be the judge if you try to spend anything less than a $1000 on an LED panel that is not a COB, you WILL be mad and possibly smashing it with a hammer.

Exactly. The only energy that ins't ultimately converted into heat is the one that's used by the plant (pigments) itself. And yet most of this energy is converted into heat in the end and only a small fraction (of a fraction) is stored in chemical bonds.

That's exactly what they do.

Hey styles. Don't let Mars know where that dumpster at! They might try to resell it?

I cant believe the 5 star reviews these platinum,mars,galaxy,vipar units on amazon! They pay good $ for people to talk good bout em? I wish there was a way to educate every potential buyer before they jump!
THE KONASSURE

who`s competitor ?
and heat in visible light is still just that heat mate
let me explain take a 3kw infrared heater and stand outside under its glow in winter I`d go with infrared leds or redsilica tubes
Then do the same thing with 3kw of green lights leds or something very narrow bandwidth with your 95% or higher efficiency
Then we'll see once you freeze to death under the green light if you still think all energy is the same

Very well said. i am with you there. Dont be cheap when buying a LED panel or you will have a useless Piece of junk

MH are very hot directly under the bulb, i would compare a 250MH with a 400w hps

Nobody said anything about 95% efficient leds, I was talking about a 95% efficient ballast. Gavita claims their DE HPS ballasts are 95% efficient. HLG-C drivers are upto 94% efficient. I have no clue what you're rambling on about. I don't think you have any clue what you're talking about either.
But yeah, 3kw of radiant power is 3kw of radiant power. It doesn't just slip into the void.
Here's a video to show you what 1W of visible light can do. That's 1W of light. 1W of power to be absorbed. Now imagine 3000 of those lasers all pointing adjacent to each other to make one giant spot. 3000W of power, 3000 times as many tiny holes in a CD case. 3000 times as much electrical tape destruction.
I highly suggest you learn some basic physics before arguing that infra-red is "heat light" while visible is not.

@churchhaze I think the context of this entire discussion is wrong.
You have resistive heating, whereby at most you can have 100% efficient heating.
Then you have light. Light is not heat.
When looking at efficiency of different light fixtures you're looking at (ideally) their ability to convert electricity into light. If the fixture is 60% efficient then you get 60% light and 40% resistive heat.
However, I can take a 600 W 100% efficient light and put it in an ideally insulated chamber. I can take a 600 W resistive heater and put it in an ideally insulated chamber. I can take a 600 W 60% efficienct light and put it in an ideally insulated chamber. They will all heat up the chamber the same amount.
Why? Light is energy, energy can not be created or destroyed. The light hits the surface of the insulation, the energy is absorbed and dissipated back out as heat.
So why aren't we growing plants with resistive heaters?
Plants are able to absorb light, not heat, albeit to a point - 85 degrees F at 1200 ppm CO2 up to 2000 umol/s can be absorbed by cannabis, so heat does play a factor. They can't absorb as much light at lower temperatures.
This light is absorbed by the plant and the energy is used to help the plant grow - it is not turned back into heat until you smoke it or it composts.
The ideal light would be 100% efficient and it would be able to deliver 2000 umol/s to a plant that was capable of utilizing all of this light. There would be no heat generated from this system. This would never happen - the light dissipates heat as it travels through the air even due to the same aforementioned principles it did with the insulation. However, if it did - you would then need to use some sort of heater to keep temps at 85 degrees.
Today's lights are no where near this efficiency - in order to deliver the amount of light the plants require they are producing well over the necessary amount of heat for optimal growth.
Perhaps in the future someone can genetically engineer a virus that will insert the DNA of a bacterium from well below the earth's surface which does use heat to grow and insert it into plants - global.warming.solved.

what was their crime...i was just about to buy way more than 1 1600w mars 2...talk to me bruh

Poor customer service when diodes burn out either you replace them unsolder then re solder diodes or ship the heavy ass panel back to get fixed. Which will cost $$$ to ship and my 1600 only pulled 671watts from the wall.
This was the 900w panel I only had it 15 months
.
And the 1200w 9 months before diode failure
go check out greengenes707 grows they have been beating hps for over a year.
your wrong watts of electricity end up as an equivalent amount of heat regardless of the conversion source. basic physics.
time for you to go back to school
all light eventually gets converted into heat, it may be stored or converted but eventually it gets dissipated as heat. The primary difference which is what you guys don't understand is that different sources convert into light as opposed to heat more efficiently than others and some conversion process store the energy before its converted to heat. but none of that changes the fact that the energy eventually gets dissipated .basic law of entropy

Itz funny....once you get building...you think....'ok im done....grow room is set'.... little do you know you are never done....The LEDBUG has infected you....i dont recommend LED's to anyone anymore.....

thanks bruh.....what kinda yields did u get off the 1600w...
