Everlight 62's ... Anyone have any info?

I've been trying to keep up with LED and was curious if anyone has any experience with Everlight chips? They are supposedly brighter than LM301b and they are more expensive (at least on digi-key), so what's the skinny?

I've been informed of mistakes on the Everlight datasheet, but was curious if anyone has ever used or tested them?

I have used everlight chips before, nothing wrong with them. Those data sheets are likely wrong though, there is no way they out perform Nichia they wouldn't even get close to Nichia performance.
There are thousands of LED packaging companies out there, Nichia is one of the only companies that produce everything themselves, they don't just purchase the parts like others do to make a chip. I have chips made myself as I want special colours so I know a bit about this stuff, I wished that Nichia would make the special colours for me though but I can not afford thier massive MOQs

Yeah, we have discussed it already and there are a few mistakes in the datasheet. The spectrum SPD shows clearly a CRI80 spectrum but in the performance table they mentioned CRI90. If they reach those numbers in CRI80 I would be impressed! Believe me, if there would be an under dog delivering better performance like Samsung or Nichia we would know that.
Their order code is also messed up and makes no sense.
What says the digikey discription?
Which diodes do they offer?
Is it CRI90 and do they mention the same high numbers?
Even if they have stolen Nichia patents in the past I wont believe they have something comparable. Cree's new midpower J series diodes are still behind Samsungs LM561c for instance. Pretty sure they have them and probably also in CRI90 but the higher flux bins are for sure not available.
There are a few brands with more expensive diodes like Nichia but that do not mean they are comparable. Production costs depends on how much you make. Nichia or Samsung calculate with millions of diodes and Everlight stock prices have been falling for years and to develope something that beats Nichia is not as cheap. Is there a release date mentioned in the datasheets, often on the last page? I've deleted the datasheet already.

Samsung confuses me, I know that they outsource thier packaging to the cheapest bidder and they do not do things in house, it's one of the only companies that I do not know where they buy thier blue chips from, unless they buy thier blue chips from Nichia I do not know how they are achieving such high performance. Cree will be lifting thier game this year to higher performances and hopefully low prices to go with them in thier mid power range, I saw somewhere that the Cree 5630 was out performing Samsungs equivalent.

Everlite are known to post false information. Only way to know for sure is to wait until they are released and test them, I test alot of chips and real results differ alot from data sheets. Even nichia chips do not perform as well as the data sheets but they are alot better than most. I think part of the issue is how they use the spheres, I don't have a sphere. My machine works differently.

That's a good news if its true. Samsung has increased their prices enormously in 2018. I got my single row F-strips in 2ft for less than a tenner per strip, 72 LM561c per strip. A comparable H-influx strip would be L04 or L06, L06 cost almost 30 bucks and L04 still around 24. Even the same F-strips cost more than 16 bucks now.
IMO, we need those Cree 5630 diodes finally to get the prices back down to a normal range.

And about the samsung die's, are you sure they simply buy them elsewhere? Makes no sense to me. If Samsung can buy them other companies could do the same. They all see what sales Samsung makes in the mid-power division and if it were that easy we would have more competition in this range. Bridgelux for instance has very efficient phosphors and as far as I know they have a deal with Toshiba. At least for their Vero and V-series COB's ..
Maybe they'll let the blue die's produce out of house but it's almost certainly a Samsung subsidiary and the patents are pretty sure Samsungs.

From memory Toshiba use Toyoda Goosi blue chips. I know that Cree, lumileds and luminus devices all use the same blue chips in the midpowers and I am using the same blue chips in the ones I have made in China.

CRI80 - 38lm...

CRI80 and 38lm means maybe 32lm in the CRI90 in the best case.
And 2016 Samsung LM561c in 5000°k/CRI80 has reached world leading efficiency with 220lm/w. Unimaginable that these diodes at that time already reached 240lm/w like LM301b.
But on the other hand 213lm@65mA is pretty good for an almost warm white diode. That's already better like a LM561c which only reach 37lm in top S6 flux bin. So they are on par with LM561c but not with LM301b or the upcomming LM301h.

If you can get your fingers on Nichia's P13 bin in 4k/CRI70 its probably the brightest diode you can get currently and if you anyway add red, deep- and far-red wavelengths you can also use CRI70. Plants don't care about CRI; its a coincidence that CRI90 fits their needs better like CRI80. As long as the spectrum fits their needs they use it as efficiently as they can.
If its CRI90 or CRI22 like from HPS doesn't matters. As long as the plant can use it they will do.
3000°k has proven to be the best flowering spectrum because it creates the most dry mass per watt. All other spectrums lower or higher than 3k produce less dry mass. Only red/blue light can keep up with the 3k spectrum and yields almost the same. Thats no bro since that's a fact.
So my first target would be to create a 3k spectrum but with lots of deep- and far-red. Far-red has anyway no effect on CRI(marginal) but it has a huge effect on plants. With a 4k base light and enough red and deep-red you can get close to 3k and the CRI would probably increase to +80 or so.

The reason I like to use cri80 as opposed to Cri 70 for a base is because of the higher blue content in the 470-480nm range. When I have tested cri70 and cri80 in horticulture mode the difference is very very minimal or in alot of cases the cri80 has actually been better. A blend of cri80 4000k and 660nm is the highest performance I have had so far. I am working on something new to get performance closer to 3 m/joule it's tricky to get the correct balance though between performance and spectrum.

You guys seem pretty smart. I am on this forum to help people out and to push manufacturers to up thier game. I do however want to nudge some of these so called professional manufacturers into buying some decent test equipment, I believe that if they do not have real test equipment they should fuck off, most companies do not have professional test equipment and that is why they can not do goniometer testing and share the tests with the community. I want to change that.

You will see me post this video now and then but I thought I would share it here so you guys get an idea of what I do


I use this equipment to conduct my tests and it's fucking good

Maybe ask Mark from Cutter about the new Cree chips, Cutter are a true Cree distributor and they pass thier low buying costs onto people directly. That's why thier Cree strips are so cheap.

Yeah, I know Mark. He has a few threads here so its easy to ask him. I'm pretty sure as soon as they hit the market Mark will get them and use them on his solstrips and other midpower modules. I am still happy with my 3k F strip and vero COB based light and 2,5μMol/J (see sig.) and I will build something new when 3,0 are possible without paying an arm and a leg.

Yeah, that's for sure neccessary! It gets better slowly but there are still lots of manufacturers who needs to be kicked in their asses.

There are some fucking idiots on this forum, I try to help by giving professional advice but they think because I don't grow myself that I don't have a clue. I don't need to grow myself I have plenty of customers that do and I can't afford a criminal record as it would ruin my business.

You can find fucking idiots everywhere, that's normal... unfortunately! There is enough research to create a good light and companies like Samsung, Osram aso. do for sure also no own cannabis test grows, lol! But to be honest, you'll find also a few reputable members

I have tests done on grows, I just don't personally do them myself because I can't afford to have a criminal record. I have done heaps of research as to what works and what doesn't.

I do need more research done, 2 things one I have seen you discussing random blame regarding UV, the other is regarding stomata control and I need someone to do that for me
