Dude, that shit is simply not true. How could I stand by n let more lies go unanswered.
Any specs on Tc of the SL80 diodes on your holder substrate.Hi, again. Because last thread was deleted ( hide adverts my company) I won't use my company name any more..
I came hire not to make business but share some information with you and discus few new tech quastion.
But back to the topic folks!
Many of you use plenty cobs in their grow box with universal ledil lens or even without any lens.
the problem is much more reflection on side walls before light hit the plants and result is vary bad uniformity. I mean very very bad...
to solve this problem i use not many cobs but as less as i can in this case i use 3 - 4 pcs point of light.
with asymmetric lens with light distribution to prevent concentration light in the center of light area.

to make that kind of light distribution you need that lens.
View attachment 3737391
as you can see in the center is similar light to +-50 deg angle. Its mean that lens works in angle 100deg with uniformity better than 90 % and this is my lab test from growbox 120x120cm

blast got 3pcs lens with cobs citizen
View attachment 3737412
explosion got 4 pcs cobs
and how its looks compare to HPS 600W with Big wing reflector
View attachment 3737410
I spent many research to make this uniformity on the beginning i try lens form kingbrite ( this is re seller citizen and cree cobs and lens form china) but the result wasn't even close to this..
forget about ledil or similar universal lens manufacture
im not try to say that only my lens is worth of $ but i try explain why is so hard to make good uniformity in growbox instead of open space, where is only one rule "more source of light more uniformity". so its opposite case...
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

citizen 3500K ra 80View attachment 3737429
citizen 3000k Ra 97 (best what we can see in red spectrum base on blu chips structure)

and finally citi horti led COB
but i even that got less 660-730 spectrum than supplemented cobs by ssl80

this is cob citizen 3500K ra 80 with 12pcs ssl80 660nm and 4 pcs ssl80 730nm like this:View attachment 3737442
I'will try write hire every day about how my light systems is woks and share my knowledge. So please DON'T DELETE THIS TREAD ANY MORE..
Lol I can't wait to see his response to this.Hybridway:
I don't know your relationship with AMARE, nor how much you love them.
But I know one thing, AMARE tech is almost entirely made in China.
I know the maker, making led for other brand too, and yes they make UV tube too.
True, the quality is high, because China can make as high quality as US, as long as you pay for it...
BTW your product from AMARE is pretty cheap to manufacter, and their patent, is far from being a breakthroug, it is more for protection and marketing argument.
I can't explain more, nor say more, take my word for what they are, at the end of the day, I don't care as long as this thread goes on
RXR2:
I am very curious of how did you made your own lenses, did you use silicon or glass? continue too share your great work. thanks
Almost all components made for everything is made on China. We all know that. The fixture is assembled w/ personal quality control in the U.S. & 5 yr warrantied here. Big difference!Hybridway:

What shitty ass light makes that pattern? My Zelion doesn't even do that? Looks like lasers. Is that it's projection? Just looks so weird for any lightBottom line is you walk into any grow shop in Northern Cal you are not going to see Amare, Tasty, PLC, Blah Blah bla Blah Blah
All led tech is still small in the big grow market place.
The OP is onto something putting all of the diodes under 1 lens
I am curious, does the single lens solve this issue?
View attachment 3738307
That is what the plants see with a discrete diode panel with individual secondary lenses.
How is it camera when it can be seen with the naked eye? lol
Google is your friend. If you don't know what a camera obscura is that's not my problem. peace
That has nothing to do with the fact the plant leaf surface is not seeing a blended spectrum, that is my point
How is it not "seeing" a blended spectrum? When you place your hand under it say 24" away do you not have red and blue covering your hand? I'm only referencing my Zelion HLs which yes if I look directly at the light I can see the Reds and blues but my eye is receiving both red and blue...... Maybe your light is different but unless it's a laser I don't see how it could be
What light is that?
Any led that uses individual diodes not under a single lens
I'm sure they are blending to some degree, but maybe they would be better under a single lens... I am not sure.
That is incredibly poor uniformity though and with 8 cobs spread out over the room it really is a lot better than just a few cobs in the middle. I don't have this huge drop-off on the walls either.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.

All I know is I don't like it and this is what the forum is all about - members putting their heads together and discussing things without a big blow out
Seriously...use google and see what a camera obscura is before jumping down someone's throat that gave you a real and valid possible answer.
