HID vs. LED.
    #836887 - 04/02/19 01:11 PM (8 months, 1 day ago)

In your opinion/experience; has LED surpassed HID in the fruiting department yet?

Ran out and bought a UFO led light in 2000 when LED first came out. Total waste of money.

Just for my own satisfaction I will be running a micro grow 70 watt hps light vs 80 watt led light.

Info on the grow light being tested.



Its interesting how the chip on board led lights automatically lower the power when the unit gets above operating temperature. The light i bought
https://www.ebay.ca/itm/30-50-80W-Full-Spectrum-LED-Grow-Light-Greenhouse-Plant-Flower-Lamp/332941387747?_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D1%26asc%3D20180124145912%26meid%3Df1315e08f1d449388f71e72e57d0de6c%26pid%3D100005%26rk%3D6%26rkt%3D12%26sd%3D352495360528%26itm%3D332941387747&_trksid=p2047675.c100005.m1851
starts out at 88 watts then drops to 50 watts without active cooling when i use a fan to cool the unit it stays between 84 and 86 watts. The hps 70 watt light starts out at 44 watts and goes to an average of 77 watts within five minutes.

Note be careful when buying from other nations make sure your getting 110 volt unit for north America or 220 volt unit for just about the rest of the world. Remember these units do not come with power cords you will need install one.

Most LEDs can plug right into 110 or 220.

If you buy cheap you'll get diminished results. Check my signature for my opinion on LED lights

You do know that 220 and 110 plugs and sockets are different right? You cant just plug one into the other.

FYI its HID lights that you can rewire for either 110 or 220. COB LED lights have the driver built in and are wired directly to the mains and come in either 110 or 220.

I am currently using LED's i bought this light here.. seems to be working good
not really sure because this is my first grow, but i used some led lights that i acquired from someone that had a bunch, they are just white LED lights from menards.. did a great job on veg..

The internal LED driver can take 110 or 220, just need the specific cord for your region :wink:. Check with the manufacturer of your lights for details.

Thanks for trying to help but please click on the ebay link above and you will discover it gives you the choice of buying 30/50/80 wattage and a voltage of either 110 or 220 and its the same with all the other sellers.

The newer LED COB units are not the same as the old separate driver and LED bulb units.

BTW 68% of legal grow companies still use HPS for flowering.

http://magazine.cannabisbusinesstimes.com/article/november-2017/facility-types.aspx


Even brand new systems designed for maximum efficiency made by corporations that spend millions on research are still using HPS.

Sorry man, that's simply not true for all LED providers. There are plenty of suppliers that can easily switch between 220 and 110 by changing out the plug, and this is usually stated clearly on their websites.

In fact, this is also the case for the vast majority of quality HID digital ballasts. This type of power supply is simple enough to implement these days, and is ubiquitous in equipment and appliances that need to be able to operate in a wide variety of common residential/commercial/industrial settings.

When you make the 110/220 choice at purchase, you are usually specifying which plug you want shipped, since it is much more economic to have a high input voltage range power supply on a single model and ship specific cables than it is to mass manufacture two different models of light or ballast and keep separate stocks of both.

The very last link posted.. "Input Voltage: AC85~265V"

and from the link you posted: "Voltage:AC110-240V"

The drivers are versatile. He can ship the same unit all over the world, just needs to know which plug to include.


I don't like that corporate weed. The recreational weed stores are 'glorified swag peddlers' according to my doctor.

Here's a quick rundown of how some of those corporations 'cure' their bud:

Chop down the plants a week early, dip in peroxide to defeat states mold requirements, debone and dehydrate overnight. Machine trim it, then hand trim the rest (that trim goes into 'pre-rolls'). Package into small 1-7gram bags and ship off to the store the very next day.

All those cock suckers care about is profit, NOT high quality cannabis. I don't agree with 'appeal to authority' logic. Cannabis at the cheapest possible production cost is not always going to be the highest quality cannabis.

Thanks everyone for the replies, so far they have been helpful.

If you all have a few minutes to watch the videos below there is a op that does a side by side led vs hid and the LED blows the HID out of the water.  Video 2 is the results.





So, imo, the possible reason for the majority of commercial/corporate farmers still using hps has to do with them simply not coming around to the upmost cutting edge technology.

These LED models will be exactly the brand and hopefully size I will be working with.  What sat ye?

Or you can read how and why LP are still using HPS lights while they are lowering their costs.

https://www.cannabisbusinesstimes.com/article/aurora-cannabis/


Quote:

This design, created in collaboration with Larssen Limited (which Aurora purchased in November 2017 and re-branded to Aurora Larssen Projects (ALPS)), allows Aurora to harness the sun’s power while maintaining the same number of high-pressure sodium (HPS) lights and using the same sophisticated environmental control system (ECS) as an indoor facility.

Cam Battley, the company’s chief corporate officer (CCO), says, “The objective of creating this … concept in cannabis cultivation is to ensure that we have an absolutely optimal environment for plant health and high yield.”

At scale, the Sky facility will produce more than 100,000 kilograms (220,000 lbs.) of cannabis per year. (Currently, Aurora Sky is operating at about 25-percent capacity with one mother room and four flower rooms licensed for sale by Health Canada.) According to the company’s most recent pro forma, it cost Aurora CA$1.45 (US$1.08) to produce every dried gram of cannabis it sold in Canada during its first fiscal quarter of 2019. Battley says that figure likely will drop to less than CA$1 (US$0.75) once the facility is fully operational. (The mean cost per gram across the cannabis industry was US$1.29 in 2017, according to Cannabis Business Times’ 2017 “State of the Cannabis Lighting Market” report.)

What helps keep those costs down is the Sky facility’s “unprecedented” level of automation and technology in the cannabis industry, Battley says. That automation and technology also allows Samantha Olivier, Aurora Sky’s lead cultivator, to oversee the facility’s current stock of 200,000 plants (with more on the way as the company waits to receive more sales licenses from Health Canada) with a team of just six employees.






If that video was real then Aurora would be using those LED light along with every other Legal producer. Phototron is right when it come to these corporations that they have shareholders to report to and have to be cost effetiive.

The first photo clearly shows the use of LED's.

Maybe they didn't want to risk a lot with new technology that few know how to master. There are a lot of reasons to not spend a huge sum on lights in order to lower your power bill. You can always upgrade later once you've done more research (it takes years to do these longitudinal grows to compare light sources) Maybe the cranes they use to lift the plants out won't operate with a bunch of low hanging fixtures. Cranes that are eliminating their biggest expense of employment(down to just 6 people). Too many factors to say its the light itself that is better.

Lets talk more subjectively about how the light compares, and how people seem to get a higher % of THC and more terpenes with LED's.

Yup that photo is of the LED lights they use when working on the plants during the dark period that's why they are red.

Sorry buddy but if LED lights worked as good as the sales men who sell it claim all LPs would use it. FYI it only takes one flowering cycle to test new lights like Induction plasma https://www.growlights.ca/growlights/grow-light-kits/induction-grow-lights/fusion-bright-300w-commercial-induction-grow-light-kit.html , CMH https://www.growlights.ca/growlights/ceramic-metal-halide-lights-cmh/945w-1000w-double-ended-de-systems.html or the newest LED lights.

As for higher THC content LP do test all their products under different lights and use a lab for exact results do you or anyone you know do that?

Sorry I will not argue subjective points because polar opposites are both right from their own perspective. You love chocolate ice-cream I love strawberry ice-cream who is right? Both of us!

FYI The LED light did not come with a plug I had to wire it myself. Please click on the ebay link and take a look at the pics this unit does not come with a plug. These type of COB chips are either 220 or 110.

Ok, one cycle to test a new light. And how many different types of lights are you going to test? the LED fixtures cost a lot. Its not like a bulb you can swap out into the same ballast.

Second, you have to change the environment and nutrients for LED lights when compared to HPS. Is it guaranteed the best the first time? 

Third, the initial cost of lights is much higher than an existing power bill. Spending 10x the price on lights to save 20-40% electricity might not even be an obtainable goal without a large investment. Investment into emerging technology--LED tech doubles in power every 18 months and is coming down in price all the time.

Red makes the plants grow. Green is the color they use when the lights are off.

Based on the link you posted, its not even a real grow light. Chinese imitation product.

I bought my first LED light in 2000 19 years ago if the power double every two years they would have replaced HID lights years ago. I bought my HID lights in 88 that i still use! That works out to 30 years cost of $300 for both ballasts is ten dollars per year. Bulbs are about 20 per year in cost. So for the past thirty years it has cost me 30 per year in lights or 900 in total. How much did you pay for your LED lights?

FYI check out a couple of the latest LED grows by LP like sugar leaf. While veg is done with LED they still used HPS lights to harden the plants before moving them into the flower room.

Please note that the flowering room has more HPS lighting in it then LED.



Yet another example of HPS and LED lighting for flowering.

SAJLMFAO If you follow the first you tube video Clive will tell you about this chip then you wanted to know.





Notice i had to wire in the plug



And like I said it uses about 85 watts.



Please notice its the same lighter i have in all my grow pics.

You should use wire nuts on those wires instead of electrical tape. Electrical tape is not designed to hold wires together like that.

Yup your right thanks for the heads up. I will be using a box and wire nuts when I install the fixture. This set up was just for testing.

BTW I recommend using a GFI socket in your grow area. While no one has died from cannabis overdose more then a few people have electrocuted themselves to death.

https://www.penglight.com/lm80-lm79-l70-and-tm21-what-are-the-differences-for-lighting/

Quote:

What is L70?
“My LED’s will last for 50,000 hours.” “My LED’s will last for 100,000 hours.” We have all heard these claims. The truth is that an LED being an electronic device with no moving parts could theoretically last forever.

Three things can kill a LED. Heat, dirty power and moisture will all have detrimental eff ects on LED life. In reality, even if LED’s could last forever, their lumen output will diminish over time to a point where they would no longer function as a useful lighting source. We call this “lumen maintenance.” The industry has determined that the LED ceases to be a useful light source when lumen output reduces to 70% of its initial lumens. This is called L70.

L70 is a lifetime measurement criteria developed by IESNA (Illuminating Engineering Society of North America) to evaluate the useful lifetime of an LED luminaire in terms of the expected number of operating hours until the light output has diminished to 70% of initial levels. or when the lumen output is 70% of its initial output.

As LEDs do not fail and “burn out” like other light sources; instead, they gradually decrease over time until they are no longer producing useful light. It is generally established that the human eye is only sensitive to lumen depreciation of 30% or more. Therefore, L70 lifetime is defined by Illuminating Engineering Society Standard LM-80-08, entitled “IES Approved Method for Measuring Lumen Maintenance of LED Light Sources.

L70 lifetime is dependent upon many variables, such as the operating temperature, drive current, and the technology and materials used to construct the products.






https://retrofitcompanies.com/myths-about-led-lighting-and-led-light-bulbs/

Quote:

MYTH 3: I’VE HEARD THEY LAST FOREVER
Another common talking point with LEDs is that they last forever. This is technically not the case. Unless an actual component in the LED fails, they will provide light “forever.” While LEDs do not burn out like fluorescent lamps and other bulbs they will however degrade and dim over time. The diode itself will begin to emit less and less light as the years pass. Still, LED lamps can last over 25,000 hours. This is over 20 times longer than an incandescent bulb and 5 times longer than most Compact Fluorescent Lamps (CFL).

Protect your LED Investment. Tips for maximum life:

Do Not Overheat The diodes and components of an LED bulb are very hot. As you have probably noticed, LED bulbs are covered with heat sinks to displace this heat. Never put LEDs in fully enclosed fixtures or warmer areas. Overheating is the most common reason for LED failure and the most preventable.
Use LED compatible dimmers Not all dimmers are universal. Avoid headaches and early failures by using the correct dimmers. Ask your supplier which dimmers work with your LED product.
Choose the Proper Application LEDs are so customizable that there are specialty bulbs and fixtures for almost every application. Know if your LED bulb will perform in your current climate, environment, or space beforehand.
In Summary: While LED technology has an amazing long life, it does need to be mindfully employed to give you the benefits it offers. Be sure to use the correct lighting product for your application, whether it be an elevator, bathroom, parking lot or factory, the best solution is the one designed to do the job.

One thing i don't see mentioned is that LED technology has been advancing at a pretty good rate and the new LED's are pretty amazing...

The videos ham posted are 4 and 5 years old and the technology has come a long way even in that short time.

Personally i use a quantum board from kingbright, which is exactly the same as HLG's cept it was over 100 less shipped. Has worked amazingly well for me so far, i'm going into flowering this week sometime..

P.S. check out grow pot cheaply on youtube.. the guy uses perfect sun led's and has pulled 3 pounds dry out of a single auto using LED..

P.P.S. having less heat and also using a lot less electricity are big selling points to me also..

Hello, Icetech.  Hope you are well!!  Those are good points about the advancement of LED technology over the few years in between now and when the videos I posted were made. 

I am looking for the big daddys like posted in the videos above that will cover at least a 4x4 foot area.  From what I understand that you're saying; there are better lights available on the market today?  Is "Kingbright" a name you would trust?  Thank you so much for your time.

No need to thank me, you have helped me sooo much on the other forum :smile:

The only thing i can say about kingbrite is that for me.. they work great.. I just ordered a second 250w (i got 250 cause A: under $200 shipped from alibaba which is 100+ less than the guy in ohio sells the SAME EXACT product for)
B: i'm not looking for massive grows.. i am doing 2 plants in flower, 2 in veg at a time.. If they are helathy and make enough bud for me.. then good..

250w isn't much in electrical costs and all of that adds up :smile:

As far as growing.. i am on my first grow, one plant is just amazing the other is decent, that came down to me learning nutrients though, not the light..

My 250w is 2 panels wide, i use a 4x2 tent (4 wide obvously) the 250 is maybe a little narrow but hasn't been an issue. For a 4x4 i would get a 500w which is 4 panels and plenty of light (to me)

For a 4x4 i would get this..
Kingbrite 480w
The main thing with quantum boards is the LM301B LED's which are pretty much samsungs newest and most efficient LED's and the V2 which is the newer version of them.. which i can't recall and am lazy to look up what it means:) I bought mine in the 3500k light spectrum..

That 480w is not cheap.. but.. nothing good is.. The 250w i use was like 190 shipped.. took 4 days to show up.

And kingbrite is a trusted name.. the thing i learned about alibaba is that those companies live on their reputation and seem to not want anything hurting them.. so companies that have been around awhile are there for a reason.

P.S. i see guys higher up complaining bout "chinese crap" well.. better get used to it.. we don't build anything better or for better prices.. our crap or their crap. it's all crap :smile:

Also.. this guy makes lights, but they are crazy expensive to me.. but that yeild... his channel is a decent one to follow, he posts like every other day..
3lb autoflower..

One last thing about why i like LED.. way less heat than normal lights.. With my exhaust fan off on my tent my temps hit 81-82.. with the fan on they drop to 72-74.. perfect. I have a buddy that uses 1000w old style light and his heat is just insane..

The v1 quantum boards use LM561C diodes.  It's cheaper than the 301B and still a pretty good diode.

Meijiu is another Shenzhen supplier.  Their fotop 800 diode boards are well suited for a 4x4.  You can buy a kit or just the boards and build your own fixture.  FOTOPS V2-600H-2

I was originally planning on building a light with four 800 boards without heatsinks.  Each one could be run at 200w for a total of 800w, which is ideal for a 4x4.

More recently however I've been leaning towards four QB 96 Elite V2's.  I would start with one hlg-480h-54a per fixture and upgrade to two down the road, after I add either 2 more 96 v2's or active cooling.

Ah thanks, i couldn't remember what V2 was for :smile: That single 96 doesn't seem like much of a bargin when you can get well over double the power with driver for less than half the price just buying a complete QB 250w?

A kingbrite QB 250w is ~$190.

One QB 96 ($100) plus one hlg-240-54a ($62) is $162, excluding shipping, wires, etc.

It comes out pretty close in the end, but the 96's can handle over 300 watts each with active cooling.

Hello, eveyone!  Hope your days are going well.

Cost isn't too much of an issue, so after carefully reading through the posts here, and around the Internet, along with much consideration; the decision has been made to go with the BLM Spyder 1200's, or Spydrx 660w

https://heavygardens.com/spydrx-plus-685w-led-grow-light.html?fee=15&fep=17216&utm_source=google-feed&utm_medium=shopping%20feed&utm_campaign=SCFeed&utm_source=google&utm_medium=cpc&adpos=1o1&scid=scplpSR-P-I&sc_intid=SR-P-I&gclid=CjwKCAjwhbHlBRAMEiwAoDA341NiB9D8zp-BeFNQKWy6OdUaVPhmMzNnak4FwzpWBD8iF8E0ygcc5hoCrI4QAvD_BwE

  Thank you all so much for your responses.  Am about a month or so out before being able to pick one or two of these BLM Spyder 1200's up.  I will post updates and let you guys know when the light(s) arrive. 

:growingweed:

If you are going to spend that much i would consider this.. he has proven results and posts vids of his grows using that light almost daily...

Ahh thanks, i didn't see their power handling.. the issue i would have with that is what is it's footprint? like when plants are getting tall how much is one of those going to be able to cover? Have never used or seen that light before.. so i am curious..

that's the one I would get. Specifically because its one of the only fixtures that spreads the light out properly. Everything else concentrates the diodes... This is the manufacturer making it easier on themselves while giving you a less ideal product.

If i had the spare cash i would go with this type of setup.. his panels have a super high density and you can build the frame however you want, the only thing i don't like bout my quantum board is that it's not spread out more :frown:

The spydrx 660w is a great light, I have no doubt you'll be satisfied with it.  However, you could DIY a comparable strip light with LM301B's for less than $800.  I plan to DIY because I have a limited budget, and I want the option to upgrade my fixtures with UVB and far red, but a pre-assembled fixture would certainly be more convenient.

Each 96 will cover a 2x2 nicely, like 800-1100 ppfd at 200 watts and 18".
