Dank Demons Perpetual 3600 watt LED 18 plant SCROG

[roll it large]

Didn't know they only ran @ 50%.
Learnt something new today,
mack.

there doing it to be safe so the unit lasts I'ts just a shame there not as advertised

if they were as advertised I reckon 3 units would have smashed what I get under 2k hps in my setup I have

I've not given up hope tho these are just what I need

peace

 

[~Shhh~]

Nice set up DD! I'm itching to see how how this works out. What kind of yields are being achieved from LED's... In the gpw sense?

So the total space the 3 panels will cover is 6'x2'?

You say that the clones will receive no veg... So as soon as they have a good set of roots your flipping them to bloom?

They're using just over 1400 watts of juice according to your power meter, do you think they're running cooler than 1000w HPS and a 400wHPS would in that room?

well, in life there are sayers and doers .well done dank demon ,man of his word . those number on the power consumption are a mixed blessing. with those low numbers i would guess something is not working correctly.is there not a switch to turn them up/down .either way sounds like you may get a big discount if they are faulty.
i do hope for the sake of this grow you do get the best out of what you have got mate. good luck .looking forward to the reply from the company ! just think big discounts! all the best .willyweed

looks like Vg is consistantly getting 1 -1.2gpw that's based on what the unit is using too

peace

 

[~Shhh~]

I've read the LED thread that Dirk posted, also skimmed through a few of the threads in the LED forums. Seems some people are getting around 1gpw (of power being drawn not headline wattage) from various types of LEDs, which is positive, but I'm wondering if the heat is truly less than when running comparable amount of HPS.... Like in the question I asked above.

I thought if it's consuming 'X' amount of watts (at source not advertised wattage) that it would produce the same amount of heat as HPS consuming the same wattage?

confused.com lol

The correct spectrum stuff I get, better buds and healthier plants sounds great!

 

[GreenPlant]

Sure I read the Heat is Less Shhh.Built in fans is an Excellent Idea!



(8 Light Spectrums etc Does Sound Appealing.)

 

[jaded1]

I find it can get pretty warm above the units but at plant height it's 2/3c higher than ambient.
The last 2 nights were the 1st where i didn't have to have tube heaters on

5w LEDs at 50% will run cooler than 2w LEDs at 100%

the harder you drive LEDs to their limit the more heat they produce

peace

 

[Dank Demon]

there being driven at less than 50% but dont sweat it you got 450-500w of plant available light per unit which is still probably more than a 600w bulb maybe even a 1k bulb

speak to the seller and ask why

peace

Here is the response mate:
Dear friend,

Thanks for your message.

That's great that you have received your lights. We got real power consumption of the light under 220V. So i think different voltage will affect the test result. Actually the real power consumption means the power you consumed to run the light, and the low power means that you can save more energy. PLS don't worry and the light is real 1200w light. Hope you can kindly understand

I will ask our engineer to test the real power consumption of the light again.

Wait for your kind response.

Best regards!

More confused now that each light runs at a different wattage so its not just to do with the mains voltage?? I will now ask them to explain that now.

yeah they might match up to a 600, thats probably a good estimate. try a similar footprint.

how different? thats kind of a whole thread in itself mate lol, but they are for sure cooler and less of a fire risk too i reckon. you need to really work the canopy and get it full of buds to get the most out of LEDS , but guess you could say that about any type of grow.

check the threads in my sig most of them are LED grows, smaller than yours but you might get some useful info.

VG

Thanks VG I will take a look at more of your grows

WE HAVE LIFT OFFFFFFFFFFF!!

This is going to be epic. Good luck mate, don't forget to don the glasses!!

Hey SupaFunk thanks for stopping by and dont worry I will never forget the glasses as without them you have crazy vision for ages lol.

Excellent setup dude. I'm checked in.

My experience re:yields is equal to slight advantage LED per watt. That is to say I yield average .58 gpw HID and I'm waiting for dry weight from LED harvest but should be the same to higher. Running a true 3000 watts each way.

Hey trillspan, thanks for the compliment and stopping by. I am looking forward to seeing what I get at the end of this myself

Hey Shh my friend hope your well. I have read so many mixed reports on LED that the only way for me to know for sure what they are like was to try them. I have heard that now there are large legal dispensaries using LED and that they are getting great results?? But I have also read the opposite?

The full area I will be covering is the length and width of a gt901 Nft tray which is: 211cm x 48.5cm because I like having a lot of watts lol. Yep the clones will be rooted then put straight in.

As for the heat thing then yesterday the temps in the loft before any lights where put on was 36c when using 1 600 watt bulb in a aircooled reflector temps where at 45c peak. I put on an LED and the temps maxed out at 38c which I was happy with.

well, in life there are sayers and doers .well done dank demon ,man of his word . those number on the power consumption are a mixed blessing.did you have a quick peek in the back of one of them to see what sort and how many transformers are in there ? with those low numbers i would guess something is not working correctly.is there not a switch to turn them up/down .either way sounds like you may get a big discount if they are faulty.
i do hope for the sake of this grow you do get the best out of what you have got mate. good luck .looking forward to the reply from the company ! just think big discounts! all the best .willyweed

Hey Willyweed mate, Nope not looked inside as it would invalidate the warranty should they need to be returned on a slow boat to China I hope I do well out of the grow as well mate.

The reply from the seller is above which I am not happy with at the moment so will be asking them to explain how if all the lights are the same why do they all run at different wattages?

I will do the best out of what I have got and post it all here for you to see mate.

Sure I read the Heat is Less Shhh.Built in fans is an Excellent Idea!



(8 Light Spectrums etc Does Sound Appealing.)

Hey GP Yeah the heat is deffo less and the fans are a great idea but all they are doing is sucking cool air from above into the heat sink which disperses the hot air out of the vents at the side. I thought they draw hot air out of the unit and feed it out above, but after putting my hand over them they are for sucking air in.

Thanks all for the vibes

I have sent them this:

Ok then I understand what you are saying about the mains voltage is different in the UK to where they are tested, but what I don't understand is if each light has 240 5 watt LED bulbs totaling 1200 watts why each of the lights has a different wattage output? If they where all the same I would understand, and like I said I have posted my grow using these lights on a forum with a lot of experienced LED growers and they say for 1200 watt lights they should be drawing between 600 and 700 watts worth of power like your description says?? I would like a more detailed explanation please.

 

[~Shhh~]

I'm good my friend. Nice to see you putting your money where your mouth is literally I've been interested in LEDs for ages but never thoroughly researched them tbh.

Ahhh, OK... so you are running them over roughly 7' x 1.5'... As you say that's a nice amount of watts for the space.

As for the heat thing then yesterday the temps in the loft before any lights where put on was 36c when using 1 600 watt bulb in a aircooled reflector temps where at 45c peak. I put on an LED and the temps maxed out at 38c which I was happy with.

Wow! That's interesting mate! So just to clarify 3 x 1200w (using circa 1400w of juice @ source) LED fixtures only upped the temps by 2c? That's pretty amazing!!

How long were they run for? Where did you take your temp measurements from...

Sorry for all the questions but these units have sparked my intrigue immensely!!

Cheers

Glad your well mate.
Sorry to confuse you mate, the temps I quoted was no lights 36c and 1 x 600 mh bulb in a air cooled shade temps hit 45c but once I replaced it for 1 x 1200 LED light temps got to 38c. I am yet to run all three at the same time as I am doing a perpetual 9 then 2 weeks after 9 and then another 2 weeks another 9, as one lots cropped the next 9 are replaced. So eventually all 3 lights will be running running but for now just one. I will report the temps as I turn on each light until they are all on. But I just went up there now and temps are 25c under the light at plant height as thats where I take my measurements from canopy height. The light had been on for about 4 hours when I took the read but the 25c read I just took the light had been on since 10am.

Hope this has answered your questions but if not feel free to ask away mate.

are all of the light spectrum's in the unit visible to the human eye?
keep on to them mate,they will prob want the lights back for a full refund though ,something is not correct with them.even tested at 220 they are still a country mile off! no where near what they should be.guess this is part of the led problem ,either false advertising or dodgy units :-( .will message you in a bit.keep up the good work

 

[DirkDiggla]

Wicked set up. I've being using led's for a couple of years now I found the 600w led's produced more than a 600w hps. I'm using the 900w version of the ones you have and results are the best Ive had, your 1200w will better still. Wouldnt get worried about the power it draws at the wall promise you results will be better than any HPS. Wouldnt recommend them with out many a grow using leds first. As regards temperature I'd say all three 1200w lights won't give out as much heat as one 600w hps. It must be worring spending that much mony on lights you havnt used but no doubt when your done youll be passing the word on.

 

[GreenPlant]

Nice you didn't pay Import tax on them DankDemon
I remember now when I've had stuff Delivered by Couriors I didn't Pay Import Tax Either
But when Delivered by Royal Mail I have!
At least Twice..

 

[DirkDiggla]

Heres a couple of shots under the mars 900w version 12 dys into flower.

Thanks mate for the compliment I am really looking forward to seeing what they can do and yeah it was a bit worrying spending all that money and the power from eah unit being different, but I am over that now and just waiting to see what will be acheived at the end.

Nice you didn't pay Import tax on them DankDemon

Nope the company that sent them marked each light at 60 dollars and I paid zero import.

I have had the response back from the supplier which I am a bit confused about lol but I think I get what they are saying:

Dear friend,

Thanks for your kind response and understanding.

Our engineer tested the real power consumption of this batch of 5w led grow lights, and we got lower power consumption. Because we used a batch of 5w chipsets with lower voltage, and this batch of 5w chipsets are expensive too. PLS don't worry and the lumen of each 5w led is same. The power consumption will not affect the function of the light. We will choose 5w chipset with high voltage next time. Hope you can kindly understand.

The voltage of white/blue led is 3.2-3.4v, and the voltage of red led is 2.2-2.4v. Because we separate leds with different spectrum range, and the ratio of each 1200w light is same. But we can not control that leds we used to the light with same voltage, so the real power consumption of each light is a little different. Like we used more 3.2v and 2.2v leds to one light, and the real power consumption of the light will be lower. Hope you can kindly understand.

You can try to use these lights, and please don't worry that the real power consumption will not affect the function of the light.

Wait for your kind response.

 

[GreenPlant]

Notice the 900watt and 1200w Have 9 light Bands whereas the lower wattage have 8.
Suppose you Could Swap LEDs Easily enough if need be !
Just bought the 900watt 5watt led version
Nearly Bought the 700watt.A single 1200watt is well over 500 gbp notes !

1200w puts out 32400 lumens.

 

[GreenPlant]

Informative..
What is the difference between 1W and 3W LEDs? Is 3W better?
Yes, our 3W chip is better; both on brightness and light penetration. Please see the chip information of our led grow light as below form. We use Epistar brand led, the website is www.epistar.com.tw and Opto brand IR led, the website is www.optp.comtw
wavelength chip size Part NO. driven voltage driven current real power
Red 610nm-630nm 42mil*42mil ES-SMHRPN42A; ES-SMSOPN42A 2.3-3.0V 550mA 1.32W real
IR 730nm 1000um*1000um ED-640IRS 1.77-2.0V 550mA 1.1W real
Red 660nm 42mil*42mil ES-CABLV45 2.2-2.4V 550mA 1.32w
Blue 460 nm 45mil*45mil ES-CABLV45 3.2-3.4V 550mA 2w We can drive the above chip more higher wattage, but that is no meaning, because the brightness will not increase so much, and negatively, the led will put more heat, and the temperature will be high, then LED's lifespan will reduce, so we use 3W chip, but only drive it around 1.6W. 90% of 1W is using very small chip, only 28mil*28mil size chip, driven 350mA, 0.7W/LED around.
Etc
