why not go back to 2012. a few names pop off in those threads and some dont lol.
@SupraSPL
@stardustsailor
@Greengenes707 /tags420
@FranJan
@guod
@PSUAGRO.
@ganja 2
@puffenuff
@SnotBoogie
@GreenSurfer
@Chronikool

but no sign of the sillystylez lol. yup those guys were the pioneers of diy and brought a ton of awesome info to the diy world. notice whos not on that list but has prob done more for diy in the past year then anyone ? ya thats right,our boy @Growmau5 doin the dirty work now and making it easy for the common man to get into top shelf led without taking out a loan to do it.

we need to glean the info from the first post which says cree is going to rule the world.i mean they pretty much already do

really?
industry gets along guys wiring lights get bigger egos Egos so big argue about each others accomplishments forgetting a couple years all of these same folks were wondering what next. Now everyone is an led expert, but no one has ever had any formal training, everyone claims to be the teacher but no one says who taught me.

Get a formal education like the engineers that design the lights you can call junk, like Kind, Fluence, and other industry leaders that work together something you guys can not understand. how sad, you fight over who was first and it looks stupid ,arrogant, and childish. you all look like children arguing over who built the best bike, when Schwinn did. you just modified it with cards etc.

I posted this thread to show you guys can not get along anymore. nothing to do with teh article just a format to attack each other. Congratulations

This place has become Lord Of The Flies!

i give credit to the 3 guys that i learned from all the time over multiple websites and ig,growmau5,greengene,and robincnn. so who did you look at for knowledge or build advice? ya seem kinda cranky lately,might wanna read your own sig lines and follow eddy's advice lol.
we all have learned some stuff over the last 6 months from @CobKits also,dude posts massive amounts of data.even though i give him shit all the time he knows im just playin and dont get all pissy like alot of "well known" members here lol.he should get more credit for the work he has put in to this section!!! i been watching this section for a very long time,longer then you have been here.just because i didnt post in here does not mean i dont read the threads.

This place is lord of the flies and I think I've posted those same words describing this place before. It's all ugly human nature and tribal, if your not in the same tribe you deserve no respect. The difference to me seems to be no one has any tolerance anymore. People used to respectfully disagree with each other but now it's just fuck off.

The Cree and San’an announcement marks at least the fourth strategic move by Cree to address the momentum of mid-power LEDs in the lighting sector. Cree developed very-small high-power LEDs as alternatives to mid-power devices going back at least to 2013 with the launch of the XLamp XQ family of components and there were similar subsequent announcements. Cree partnered with and invested in Taiwan-based Lextar in a mid-power-centric deal. And in 2015, Cree signed a cross-licensing agreement with Epistar that presumably brought Cree some mid-power intellectual property (IP).

Now, however, Cree will own 51% of a new venture to be called Cree Venture LED Company, Ltd that will be based in Hong Kong. Presumably, San’an will supply the mid-power manufacturing expertise while Cree supplies the IP that has yielded perhaps the highest-performing high-power LEDs on the market. Apparently, Cree will sell the LEDs from the venture in North and South America, Europe, and Japan, and both companies will serve China and the rest of the globe.

“The addition of the mid-power LED products in this new joint venture to Cree’s industry-leading high-power products gives us an unparalleled LED portfolio,” stated Dave Emerson, Cree LEDs senior vice president and general manager. “With our LED systems expertise, customers are able to work with our existing channels to find the best LEDs for their applications.”

The question really is such a deal coming too late for Cree to gain a real foothold outside of high-power applications, of which there remain many. Still, the mid-power momentum has clearly hurt Cree.

The company just announced third-quarter results for its fiscal 2017. Revenue of $342 million was down 7% compared to the same quarter in 2016, and 15% compared to the second quarter of 2017. But Cree chairman and CEO Chuck Swoboda said that LED products performed at or above target levels whereas the company’s lighting business was hampered by soft market conditions.

It would be more accurate to say that the WOLFspeed mess is what killed this Cree quarter not the led bus

The other thing that cree announced just before was the new chips...
http://www.cree.com/led-components/landing-pages/nx
They are still pretty vague and just a general overview about it, but things like new packaging is interesting. The Da1000 chips they have had but not used in a package are a flip chip design, so that is a nice change...dmax seems in line for that. Waiting on more info from them, but all looks like the improvements that needed to be made...contingent on actual data coming out of course.

Here's the release...


Generation Lighting Systems
APRIL 17, 2017
DURHAM, N.C. -- Cree, Inc. (Nasdaq: CREE) announces a major LED breakthrough with the revolutionary NX technology platform that will power the next generation of Cree’s lighting-class LEDs. The NX technology platform enables the new Extreme Density (XD) LED family that delivers up to four times higher lumen density than Cree’s previous generation of high power LEDs. This new technology platform makes possible innovative new designs, eliminating current constraints for a wide spectrum of lighting applications such as color-mixing, directional lighting and industrial lighting.

“Cree continues to deliver LED innovation that fundamentally changes the rules and propels the industry forward,” said Dave Emerson, Cree LEDs senior vice president and general manager. “Our new NX technology platform builds on Cree’s advancements in epitaxial structure, chip architecture and light conversion, and leverages Cree’s lighting applications expertise. Unlike other technology platforms adapted from LCD backlighting applications, our NX technology platform was designed from the beginning to dramatically improve the performance of LEDs in lighting applications.”

The new NX technology platform embodies advances in a number of components and technologies, including the new Dmax™ LED chip, a more efficient phosphor system, new package designs and simpler manufacturing processes.

The first product available in the new family of XD LEDs is the XLamp® XD16 LED that delivers a breakthrough lumen density of up to 264 lm per square-millimeter, which is 50 percent higher than the best LEDs currently available. Specifically optimized for applications that require high light output and high lumens-per-watt, such as street lights and high bays, the new XLamp XD16 LEDs enable higher performance luminaires with better light control. In addition, the ceramic-based XD16 LED addresses challenges with assembly, thermal design, optical design and reliability that have been experienced with other competing LED technology platforms.

Engineering samples of XLamp® XD16 LED will be available by late spring, with production quantities to be available by the end of summer. For more information on the NX technology platform and XLamp XD family LEDs, please visit www.cree.com/nx.

this is the Cree entry to frameless packages, pushed hard by Seoul Semi and Nichia, the issues with these packages is the difficult assembly, these puppies dont like to lay flat in reflow

Cree and mid power is a love hate relationship, most everyone is plastic, Cree remains ceramic and their lack of penetration is what has inhibited generational uptick, they have lots of data supporting the benefits of ceramic but cant get it to stick. I am sure the SAAnn deal will well and truly resolve that. My take on LM561, PMP(plastic mid power) and who did what is Fluence and a few others were into this tech early trying to get away from purple rooms and the right efficacy numbers, however when I look at the numbers on this NICHIA remains top dog, just throwing a cat into the room

mine werent even real UFOs

i got mine in 08, after high times put them on the cover. i used to drive 4 hours down to the bay to get them from some guy who was importing knockoffs for $350 a piece. by 2012 most of them had burned out fully or halfway and the garden was a crazy mix of SE hps and half-functional blurples. i still have them and should tear them apart, theyre heavy and prob have huge heatsinks. i got my first "HQ" led in 2013, a solarstorm. i think those were just catching up to DE HPS at the time.

its fascinating to look back and see what they were pitching

https://www.icmag.com/ic/showthread.php?t=81189

"..in the first trial that finished, the grower reported a 12% increase in yield for the UFO-grown crop, which was side-by-side with a 400-watt MH lamp-grown crop. Not bad when you consider the UFO runs on only 90 watts."

20% of the power consumption - how can i lose?!?!

You will find that they used ally sheet as heatsinks..
Pull it apart and see..
i bet my bottom dollar on it..

 

[bakedPotatoe]

Thank you I forgot how I defended full spectrum lights it just sucks Mars had poor led chips lol

Which is why we are seeing panels coming out with or like qb.....
The idea was fine just the use of shitty chips,can you imagine they used good chips from the start?

we all have learned some stuff over the last 6 months from @CobKits

ive learned just as much or more here than ive taught in that time, isnt that what its about? this art is such a moving target, what was "right" or "best" a year ago is fleeting, but as a community were all better educated on all things, whether its growing, or spectrums, or efficiency, or heat management, or wiring, safety, etc. and hopefully we can continue to push each other in positive ways

the day i stop learning put a bullet in me. paying forward is just a part of that, i wish people would put the egos aside here., whats that old saying something about true wisdom is understanding the magnitude of your ignorance, or somesuch.

yes its natural for any trend for the early adopters to say "the place aint what it used to be". the old "vets vs noobs" ive seen it in many other areas, particularly message boards. everybody was a noob once and the real challenge involves educating and engaging the next crop of enthusiasts so our art continues to grow.

pay.it.forward. I was fortunate to catch the tail end of what many consider the golden age of this site, and it was very educational (if not overwhelming even for a tech guy), and as some people like to point out (repeatedly), we are still asking the same questions now that we were two years ago. the difference being there are many many many more cob rigs out n the field than there were back then.... it is still a tiny fraction of the number of grows out there, so theres still plenty of work to do. If 2 GPW isnt the industry standard within the next few years i consider that a fail.. and lighting alone probably cant even accomplish that

How big is it?
Lol mine must have been the real early days....

 

[CobKits]

same diameter as the light itself. guessing about 3/16- 1/4" thick on the base, has some short fat pins
