Wow you have tested lamp SolarECLIPSE™ 350+UVB, Its funny and real story about 6-7 month ago ive been in china and i saw that product in UV tube factory. A i said that nice combination source of light but in low quality components in driver Power factror less than 90 and quite too heavy chassis 15 kg for only 350W with cheap fans.

They ask me what i will change if this product will be for me. i said : LENS drivers and fans.. they calculate my advise but the price was to high for customers who order this produce. Now i know that was amaretechnologies. So the world is quite small..

Any way UV-B/C tube in that lamp is very important and gives you nice boost THC level in last 1-2 week before harvest. I dont know why only Australian producer make UV-b/C supplementation I know for now only solar storm and solar spec .

But ill use UV-B and UV-C in my light system too in ratio 15 % uvc and 33% uvb with 20W tube for 120x120 growbox ...

And i hope you will make this test on your plants.

And we finally know how deep the rabbit hole is... :)

I will read and follow this and try to somehow grasp some bits of knowledge that fall off the table. This is interesting!

Yes i read this, I not biology men but from my research when you put UV light it the end flowering its make :

First UV C is biocidal effect so its start slowly killing your plant and protect your crop from insect fungus and any mold.

But most important is plant reaction for that radiation. Plant start program self defense its base on transport every resource to leafs to keep as long as possible process photosynthesis. During that process active substance like THC naturally concentrated in top of plants.

Second UV B stimulate plant to improve photosynthesis process ( its important because w got only 1-2 week before plant die.. )

Conclusion.

advantages:

Increase THX level
protect harvest from insect mold fungus.
Instant dry ( plant is almost self dry)

Disadvantages:

PROTECT YOUR EYES!! I mean serious. even 20min in UV-C can make you blind for rest of your life..


I got all setup for this test and ill send it to US to make real test on real plants
and i pretty sure every body are curious how significant is that effect. So i send 4 my lamps and 2 of them will work without UV in last stage mature process . and 2 plants will get UV-B/C radiation at the end on flowering.
And thc lab test tell us true.

UV-C doesn't hit the ground outdoors(atmosphere ), yes great for antimicrobial/fungal ...............I would be concerned about possible dna damage on pollinated plants(seeds), but that hasn't been proven I think ?

Why would you waste half the light on the walls to get "best" uniformity?

Uniformity at 30cm distance with 8 CXB3070 (400W total) without lenses or muck like that over a 100x100 (1m2) area is great. No need to go any higher. In fact even at 20cm it's still fine.

Yeah, I did a thread and live grow with the Amare SE-450 & the SunCloak 4416 vertical system. Wasn't the best grow on my part but it did show what these lights are capable of even under less then optimal conditions.
Both lights use quality components here in the U.S.
My next grow will implement UV-B+C in half of the grow space. I'll be getting the final product/buds tested to see if the lab results show much difference in the Terpen profiles & THC content. I know it's been done before but I'd like to give it a shot myself & share the results here on RIU.
I've talked to a few growers who've tried using UV but they went a lil overboard I think & hurt their plants.
How do you plan on implementing UV to the housing of your lights? As far as I know, the bulbs are the way to go for now because LEDs haven't been made to last in UV. Maybe that's changed by now though. I've seen some expensive uv diodes on the mkt.
I'd like to give the Xplosion 550 a shot over my plants. Sounds like you've put together an innovative product that should do real well. Good Luck!

Here is -20- cobs over a 4x4 tent, at 30cm. Our friend @rxr2 is only measuring 100cm across, so it might be more fair to ignore the outer measurements, and we get uniformity more like 538/979=0.55. Average PPFD would be a little higher too.

But matching 3 or 4 cobs against 20 bare cobs is impressive. I guess if @Malocan was a light manufacturer he'd have a 10x10 grid to show, instead of 11x11 :)

8 cobs would not be better.

Wrong, its not about 8 or 2 or one point of light but problem is that COB


have gaussian light distribution like this
Laser_gaussian_profile.svg.png
most of light is in the center and trust my i can make test with your grid and my result will be same 80-85% uniformity for all surface but in correct distance. which is in my application between 60 and 90 cm above the plants.

another thing you dont loose your light by using lens! by using correct lens you can use even 70-80 total output from led!

In your case with out lens you use only 30-45%! rest has wasted on side wall..

Look at the example i got 2 distance than yours 60vs 30cm my signal should be squarer times less then yours. But i got the same par radiation in center my 930 vs yours 939 umol m-2 s-1 same situation is on the corner i got 600 and you got aver. 600 too

so 4 pcs cobs and same power 550 W is equal to 20 pcs cobs but without lens..

I know that its hard to fit good lens for ours cobs ( it doesn't matter cree or citizen size lighting is similar) but if you use right lens you wont ever use 20 cobs...

in next 2-3 week ill try sent to US some package of sample my lens and you will able test them and make own tests on them..

I'm not wrong, because I agree with you completely :) Tower of babel sometimes in here. I was trying to show @wietefras how good your lights were using only 3-4 cobs, and that even with 20 bare cobs at 30cm, uniformity is not perfect. That's all.

Those are @Malocan 's measurements, by the way, from here: https://www.rollitup.org/t/spectral-lightmeter-gigahertz-optik-msc15.913239/

You can see we discuss light spread in there too. 120 degree FHWM, with reflectors and without. It's why we are impressed with your footprints,

Tom,
I have to address this comment as I do not believe it to be true. There's so many out there trying to bash Amare because, after all, they are THE light to beat as far as performance & craftmanship is concerned.

How is it you saw an Amare light at a Fluorescent light factory in China? That's not even possible. What would be the affiliation & why would an Amare be there? Doesn't make any sense guy.
Also, the reflector lens array w/ supplemental enhancement diodes & removable lens is designed & patented by Victor & Amare. They own that design which is why you'll never see another light like it. Maybe similar but never the same. Also, they use some of the highest quality components available on the market today. I own this light & know for a fact it's built using the best craftsmanship & components I can find in an led grow light.
Many a company attempt to discredit Amare because they are at the very top of the chain. It would serve you best to focus on your ideas & innovations by not slandering the originator of the commercial COB grow light.
Nobody has or even can offer to sell you the Amare light for re-sale. It's patented design is one of a kind. As you can see, other companies, including yourself understand the huge advantage to enhancing the white cob. I give you props for your design & research. But please do recognize where it all started & credit where credit is due.
They're called the white light revolution for a reason. Even the all white light cob comp. that started off knocking the enhancement of the white cob, saying its unecessary, realize they are at a huge disadvantage & are trying to find a way to increase their CRI & add the much needed nanometers to grow pot with the highest success.
I'm glad you recognize the importance of enhancement but you do not grow Marijuana & have not tested your lights on cannabis. I am all about the truth & cannot stand-by & let non-truths (put nicely) to be told about the original innovator of the enhanced cob grow light product, called Amare.
With all that said, my offer stands to test your light. But it would be in a side by side comparison run against Amare Technologies, whom the owner is a MJ grower, built & specifically designed his lights to give the absolute best results growing Marijuana.
So, please do not slander the company by saying you saw their light at a uv bulb factory in China in which offered to sell you the Amare product. Also, please do not spread rumors of low-quality components used either, as that is a well known fact to be the farthest from the truth.
Top-bin Cree is used, the fans work real well & are close to silent, the lens is solid glass & is the only company to offer the reflector w/ removable lens built in. The surrounding monos are patented & can not be resold to you or anyone else. They've been dealing w/ the same t-8 uv manufacturer for the past 2.5 years & the uv bulb company has nothing to do with Amare at their factory. So, do not attempt to smear rumors around. If your light is that good, we will all see when it someday makes it to the U.S. through a separate vendor that you will not personally be able to have quality control over.
Amare upgrades every time improvements are made possible.
Like I said, I'd be happy to test your light in a side by side against Amare & we can all see just how well they each perform.

In fact, it does the opposite of what you all think it does. You're all hopeless so good luck figuring that one out.

Next step in run for best light for your plan is spectrum. Single cobs even those best like cree or citizen got very high Out put but they cut out spectrum above 630 nm... its because they use blue chips and phosphor. any spectrum above 630nm from blue chip is less efficient than when you use red chips like osram ssl80 did. hire is some spectrum citizen cobs
View attachment 3737426
citizen 3500K ra 80View attachment 3737429
citizen 3000k Ra 97 (best what we can see in red spectrum base on blu chips structure)
View attachment 3737433
and finally citi horti led COB

but i even that got less 660-730 spectrum than supplemented cobs by ssl80
View attachment 3737436
this is cob citizen 3500K ra 80 with 12pcs ssl80 660nm and 4 pcs ssl80 730nm like this:View attachment 3737442

That's way too much truth for this forum... I love the concept, but still too much green, and a bit high FR. If you use a warmer cob than the 3500 cri 80, like the 3000/2700k, or a cri 90 that has the red peak at a higher, better, red wavelength and a little higher FR already you could replace for example 2 of the FR with 660. The end result would then have less green, slightly less blue, and more red. It would be more like the citi horti but without the unnecessary high blue peak. Right now it's more like a complicated way to create something similar to a 3000k cri 90, which yes is better than 3500k 80 cri but you're appearantly in a position to create something much better still.

Anyway, you're way ahead of the pretengineers and light sellers here, good luck with your product.
