Are LED's That Good?

[Eric Farley]

Really? LMAO.......

Let me guess - it's "blurple" ? OR cost over 2 grand!

Hmm.....

Idk what blurple is and no it didn't cost over 2 grand it was $1,600 and I guarantee you I have at least broken even and most likely saved more than I spent on that in the last 2 years on light, ballasts, reflectors, ducting, A/C unit, bulb replacements, electric bills (I pay about $15 a month for my grow, how about you?). You can knock LED all you want because it cost more initallly but that's just your own inability to consider the long run instead of an immediate return but at the end of the day over the last 2 years I paid less than you have on your precious HIDs over the same period. Fan boys *rolls eyes*

how is a 19 dollar Citi 1812 cob expensive,, or an 18 dollar meanwell driver?,, a 3 dollar cob holder, an 18 dollar heat sink,, seems pretty cheap to me?

Watt for watt LEDs are more expensive than HID lights, a 600w LED will cost much more than a 600w hps. I know there are exceptions but listing the cheapest single LED setup does not compare to a HID light. Not to mention what the heck meanwell are you paying 18$ for , all the ones i see that power LEDs are between 50-200$ unless you are planning to only power your LEDs fan....

It's not about yield, and I'm not talking commercial here. There is a difference per application that you and Odin seem to be forgetting. Not everyone here is growing in a warehouse.

Flower initiators have been shown to reduce finish time by as much as 5 days, depending on the amount of light and time run. They can be made for less than 20 bucks, or added to a DIY light for even less. Is 5 days worth less than 20 bucks? you decide.

I'm not here to argue about HID, I won't use it, too much heat for my small set up. In the future? Maybe, if I build a solid walled grow space. For tents, LED hands down.

Heat is based on watts used , not lighting type. HID lights do not produce any more or less heat than an LED with the same wattage.

Blurple is the color of the lighting spectrum, it was a thing LED makers did to try to make their LEDs produce more PAR, problem is they forgot about half the mccree curve in their lighting spectrum which often lead to metabolic issues. If you are using blurple LEDs you lights are not better than HID lights no matter what, because the lack of spectrum will never allow your plants to produce their full terpene profile. New LED makers use white light LEDs, instead of blue, and red that produce that ugly blurple color.

LED lights are better at converting their input to the desired output, thus less wasted energy in the form of "heat"

Read my post, watt for watt the heat output is the same.

Honestly, LEDs work good but they are expensive, HID works good and it's cheap, the main difference is the amount of electric they use, if your electric is cheap (mine is really low) HID might be the best for you.

 

[TacoMac]

I'm seeing more and more people use these LEDs and I'm starting to wonder if they are as good as people make them up to be..

In a word, no.

The problem is that there is so much absolute crap out there that it's far more likely you'll get a shit light than not.

Everybody loves to brag about their particular shit because they paid for it, and they're welcome to it. But the indisputable, absolute fact is that MH/HPS has worked well and is still by far the most absolutely reliable light source out there and has been for decades.

We now return you to your regularly scheduled LED/COB brag-fest already in progress.

cringe, youve got the logic of an imbecile. Candles work well too jack ass.

FACT: while hps growers were sucking each other off over 1 GPW grows, LED growers were getting close to 2gpw, cheaper, cooler and safer.
The opinion from @TacoMac is luddite, idiot contrarian shit.

Read my post, watt for watt the heat output is the same.

In a physics lab closed loop sure the overall power pulled would equate the same heat, but at conversion of electrical to radiant the lights themselves are not equals, one will output more heat as a result of wasted energy and one will have put out more radiant light as a result of being more efficient.

it's not

youre thinking a blow dryer creates as much heat as a led watt for watt? It doesn't

I think you both need to do some reading and research, 1 watt of any source = 3.41 BTU. Here read this thread it can explain it much better than i can.

https://www.rollitup.org/t/heat-from-1200w-of-1212s-vero-29s-cxm-22-cxb3590-compared-to-2x-600w.936071/

Here's a great quote from that thread

Yes, good LEDs put out more light.

That light eventually also turns into heat..
Photosynthesis while endothermic is very inefficient so negligible.


Energy that's stored inside the plant doesn't turn into heat (only a very tiny amount).
So 1200W of LED practically produces just as much heat as 1200W of HPS.

But the radiation of the 2 sources is different.
HPS has some IR which will radiate right on your plants and you can assume all of that will turn into heat the moment it hits your plant.
So even if room temp is equal, plants under HPS will have warmer leaves because of the IR radiating on the leaves. Something to consider.

Even funnier if you're trying to grow with incandescent, should be very hard since incandescent bulbs are extremely efficient IR producers and will easily fry your plants even if ambient temperature isn't very high.

And here's another

in a room 1200W of anything is 1200W

will produce the same amount of heat

cobs will give you more usable light for that same 1200W, or an equal amount of light for a lesser wattage, like 800W

You guys should read up on the first law of thermodynamics.

I just want milk that tastes like real milk!

 

[Odin*]

doubling down on the stupid pills today eh @Odin* @Dr. Who

Have either of you ran LEDs, are you supplying us with opinions stemming from what was that, confirmation bias

be easy guys

Oh shit! Stupid pills? I shoved a whole bottle up your ass in the "Orange Mocha Frappuccino" enema thread (Flushing).

Fucking dumbass (with all of those stupid pills in there), I do not need to waste time/money/space testing LEDs/COBs as I already know that they are not capable of supplying enough light for 8' plants. Sure, they're great for your closet, but they are a shitty source of light for large plants/space. Successful commercial operations utilize cubic feet to their advantage. LEDs/COBs are sub par in this category.

Now go get your Mocha enema to flush out all of that "stupid" you've been running around with.


All in good fun.

And that right there is pretty much the entire LED/COB crowd in a nutshell.

Stick with your HPS, OP. Any time you mention anything about LED/COB lighting, they all come out of the woodwork, contradict each other for pages, post 9 kinds of bullshit and insult the flying hell out of everybody.

The only real FACT are the ones I stated:

• Your HPS/MH has worked well for decades and will continue to do so.
• The LED/COB fangirls can't even agree among themselves, let alone with anybody else.
• The LED/COB market is more flooded with absolutely shit products at this point than you can shake a stick at.

It's probably going to be another 5 to 10 years before the shit gets weeded out of the LED/COB market and the creme floats to the top to where it's much easier to make an educated decision.

So no, you haven't ran LEDs but offer opinions..

You cant explain it because you dont understand it.

The conversion of electical energy to PAR is far more efficient in LED than HPS.

If you have a cold room or dig foxtails and higher energy bills than it may be useful.

 

[Heil Tweetler]

make an educated decision.

Clown you make a habit of avoiding education.

Learn to read. That's not what he is saying. He's simply stating that a watt of LED consumes the same amount of power as a watt of HPS/MH and in so doing produces the same amount of heat.

A watt is a watt.

Light conversion has nothing at all to do with heat output, you really need to do some research , read the first law of thermodynamics and that thread i posted, you obviously have comprehension issues and like to spew off at the mouth.

Right, but one light can use that same amount of energy more efficiently in the conversion of electrical energy to radiant energy.

@Yodaweed How much studying of Thermodynamic black boxes did you do where the plant was in the closed loop?
