"The basil in our office continues to grow under @Bridgelux 3500K Class A array! We can't wait to make fresh pesto!"

So what will happen to our friendly Veros? Will the new owners of B-lux continue to produce Veros? Did they get access to Toshiba who is/was B-lux GaN on Si partner/supplier? Toshiba isn't technically in the LED biz it seems saying Greenstar Lighting Products Inc has taken over their N America operations:
https://www.toshiba.com/tic/led-lighting
"Due to a reorganization of international operations, Toshiba International Corporation's (TIC) LED Lighting System Division has discontinued its operations. Toshiba Lighting in the Americas has transferred to Greenstar Lighting Products Inc., a wholly owned subsidiary of Toshiba Lighting and Technology Corporation (TLT).

Question, questions, questions. So looking for additional COBs manufacturers is a good idea IMHO. Or just sticking to CREE for the near future seems a good bet too :). And if everything goes as planned I'll be using my Luminus Devices Xnova 4000K COBs alongside some G1 3000K Vero18s in my flowering space so maybe we'll see If LD XNovas can hang.

I'm pretty sure Nichia has updated their COBs recently so maybe they're a little more sturdy and hopefully more efficient. Pretty sure Luminus D has upgraded their COB line too. Haven't really checked though.

shut up and dig your garden
you have no idea of optical behaviors
A slightly different spectrum doesn't explain a 40% drop in lumen output.
Those high CRI cobs are inefficient relative to the normal ones.

the efficient is not the real Problem!
it´s more the lost in the red region, and this part is the workhorse in photosynthesis

LER at CRI ~80 :: 320 to 340
LER at CRI ~90 :: 250 to 270
the rest of the Math is yours

btw. the sun runs at ~93 Lm/W at 5600K, with a CRI of 100 per definition

I'm actually saving up to buy some of these for my ceiling fan. Prices are ridiculous but they are the company to beat in high CRI LED lighting. Worth growing with??? IDK bros and bras but with beam shaping and color shifting it would be fun to try some :).



Pioneering lamps using LEDs built from pure gallium nitride substrates (GaN on GaN™), Soraa has made ordinary lighting extraordinarily brilliant and efficient. Soraa's full spectrum GaN on GaN LED lamps have superior color rendering and beam characteristics compared to lamps using LEDs created from non-native substrates. Soraa is located in Fremont California, where it manufactures its GaN on GaN LEDs in the company's state-of-the-art facility.
  • Dr. Shuji Nakamura, inventor of the blue laser and LED
  • Dr. Steven DenBaars, founder of Nitres
  • Dr. James Speck of U.C. Santa Barbara's College of Engineering
Soraa is the only LED manufacturer using perfect GaN on GaN™ crystals for its products.
Why use GaN on GaN™ LEDs? They're simply better:
  • GaN on GaN™ LEDs emit more light per LED material than any other LED
  • GaN on GaN™ LEDs handle more electric current per area than any other LED
  • GaN on GaN™ crystals are up to a thousand times more precise than any other LED crystal

http://www.ledinside.com/news/2015/8/why_are_chinese_led_manufacturers_acquiring_large_intl_manufacturers_less_profitable_businesses

Why are Chinese LED Manufacturers Acquiring Large Int’l Manufacturers Less Profitable Businesses?
Chinese LED enterprises are spending a fortune in acquiring foreign manufacturers in 2015. A couple of examples include Shenzhen Kaifa Technology (Kaifa) recent acquisition of U.S. LED manufacturer Bridgelux, Shanghai Felio Acoustics interest in Osram’s distribution channels, and Go Scale Capital’s acquisition of Philips Lumileds. Why has there been an increase in international mergers? What are manufacturers motives? Below is a summary of Chinese media Alighting’s prove into these issues.

Why are international manufacturers searching for Chinese buyers?
From a macroeconomic perspective, changes in the global economy has presented new business opportunities for countries, said Congfeng Zhang, President, Innoev New Energy Technology (Innoev). The rising Chinese economy and comprehensive national power has allowed the business to further expand. More leading manufacturers are entering the international stage, or acquiring foreign companies to enter other markets. Some successful merger cases in other industries include Lenovo’s acquisition of IBM’s PC business and Geely’s merge with Volvo. Similar trends of Chinese manufacturers merge with renowned international manufacturers are also being observed in the LED lighting business recently.
Main reasons foreign companies prefer finding Chinese acquistors include China’s good economic situation is beneficial for the industry and manufacturers developments, said the Zhang. Moreover, listed Chinese manufacturers have a strong financial foundation and sufficient finances to avoid investment risks. China’s large consumer market also ensures manufacturers plenty room for further developments, and lastly globalization of the world economy has made the integration between east and west a necessity. Complimentary partnerships can improve manufacturers’ developments.
“Chinese manufacturers are the only potential buyers,” said Fairtek International Chairman Peizhi Dong. “If international manufacturers do not sell now, when their still valuable, they will only see their value shrink in the future.”
According to Yinshui Peng, General Manager of Romney Opto-electronics Systems (罗姆尼光电系统技术), the differences between Japanese and Korean manufacturers LED chip technology is not as significant. Hence, the chances of these manufacturers to spend excessively on the acquisition of these companies is remote.
China is also the world’s largest LED downstream product manufacturer that is looking for potential opportunities to move into the upstream market sector, said Yujie Lin, General Manager of PN-Stone. Moreover, listed Chinese manufacturers have much better financing channels.
LED technology might have taken off later in the Chinese LED industry, but the country is currently the world’s top LED manufacturing hub, and supplying more than 80% of LED products to the market, said Hangzhou Zhonghen Power Energy CEO Shi Wen.
“When products meet market conditions, high manufacturing costs are a disadvantage,” said Wen. “We have observed Chinese LED companies and foreign counterparts prefer to sell their companies when prices are right, so they can focus their finances on their company’s strengths. Instead of being gradually absorbed by Chinese manufacturers. Global surveys suggest Chinese manufacturers are the most qualified candidates.”
The LED industry in China agrees intense price wars is the main reason that international manufacturers, such as Osram and Philips are selling their less profitable lighting businesses to focus on more profitable niche market applications. But what about Chinese acquisitor motives?

Reasons behind Chinese manufacturers acquisitions of foreign companies unwanted LED businesses
Factors Chinese manufacturers have taken into consideration include innovation, intellectual property rights, and expanding international markets, said Innoev President Congfeng Zhang. “International manufacturers tend to emphasize technology innovation, and are better at transferring scientific research results into products and market applications,” he added. Continual technology innovation can bring considerable economic benefits to manufacturers, and stabilize the R&D team’s dynamics and stability. This is the basis of LED industry developments. Chinese LED manufacturers need to follow international norms if it wants to perform well in oversea markets, intellectual property rights are unavoidable. The LED industry’s core technologies include patents. Especially in the upstream LED industry, a few international oligarchs control LED chip and package technologies, such as Philips, Osram, Cree and Nichia.” he added.
Acquisition of foreign companies is a shortcut for Chinese manufacturers vying to enter international markets, he added. Acquiring foreign companies intellectual property rights and patent rights can greatly help Chinese companies. All these trends involve international acquisitions that effectively use the company’s existing employees, distribution channels, and resources. This is the most effective method, and why leading Chinese manufacturers have been enthusiastic in merging international companies.
Peng also agreed with the above viewpoint. Mergers with foreign company can assist Chinese manufacturers in reaching their internationalization goals, and acquire certain business channels. Secondly, Chinese manufacturers especially desire LED chip patents that leading international manufacturers have an extensive portfolio. Thirdly, the company can build on the international company’s brand value. There are Chinese manufacturers that are truly international yet. Building a global brand requires finances and time, so acquiring an international company is the fastest short cut.
Some perspectives on the market point out Chinese manufacturers decision to acquire international manufacturers was affected by the potential expiration of nearly 20-year old LED patents in the industry. However, an engineer from Guangdong Solid State Lighting Research Institute (GSSL) Longfei He noted the “patent theory” was flawed. “Patents in the LED industry tend to be patent families, and are not single patents,” he said. “If the patent expires, and another patent application is filed for related technologies than the patent has not expired. In other words, this is a false proposition, manufacturers are no longer filing a single patent to protect their products, but are trying to increase the number of patents they hold.”

Advantages and disadvantages of frequent mergers for Chinese manufacturers
Chinese manufacturers’ international acquisitions mostly reflect domestic competition. One evident advantage for Chinese manufacturers acquisition of international manufacturers is it greatly shortens the time and resources needed to develop the company’s brands and sales channels, especially in the oversea markets, said Wen. Chinese companies have started much later on the market, and it’s more difficult for them to develop their brand in overseas markets. However, by merging with an already well known international enterprise, companies can quickly acquire brand recognition, distribution channels, and integrate resources.
As for pros and cons of these mergers, Dong believes this should be approached from two perspectives. “Merging with foreign companies can greatly strengthen Chinese manufacturers globalization and patent strategies, but integrating the international company and transforming into it into a valuable asset can be a huge challenge. I don’t think the outcome of all these mergers will necessarily be equivalent to ‘1+1>2’. Most manufacturers will encounter difficulties during the integration process with the newly acquired companies.”
In contrast, Yujie Lin, General Manager of PN-Stone noted “The benefits for Chinese manufacturers outweigh the disadvantages. Chinese manufacturers are able to improve their brand recognition in domestic and international markets. Moreover, consumers will no longer believe foreign brands are better, but will gradually recognize domestic brands.”
However, industry insiders have voiced their concerns. “I believe most manufacturers participating in these acquisitions are unprepared. Many do not have an international mindset, and have not made sufficient risk assessments. This can be observed from several aspects: the first is financing issues, in this aspect we can observe ‘boa constrictors trying to swallow elephants.’ The acquisition funds are really just one of the many costs to follow. Do manufacturers have the budget to cover many of these unforeseen costs. This is not the most serious issues, the biggest problem will be management and cultural clash. I have worked in both Chinese and foreign companies before, Chinese manufacturers tend to emphasize fast reaction rates and efficiency. However, foreign companies tend to follow protocols, if the acquired company cannot adapt to the new Chinese management styles, they will definitely fail. Lastly, is wrong market positioning. Manufacturers that have never been involved in branding, will not know how to position their products in the market. This will include Chinese lighting brands that might not have international branding experience.”

my biggest fear with all the mergers is the lowering of quality production standards as they strive to squeeze the profits out. Chinese companies on their own are not known for keeping high standards and are more apt to cheat.

second to that I see cuts in research budgets.

are my fears rational ?

^^^Your "fears" are completely rational from a more pragmatic viewpoint. A more optimistic view is better tech getting into Chinese state factories, resulting in better budget panels and forcing existing companies to innovate or die though that maybe a bit simplistic. Tech innovations can shatter economic models. See the lightbulb business as an example. All this stuff the Chinese are buying could be moot if someone like CREE introduces the next COB like innovation.

Is Bridgelux the new Betamax of sorts? The problem even with Cree is bottlenecking in the supply chain....if it weren't for a single reseller vendor, would the CXB's be as popular? Before that, top bins weren't hard to source, but definitely suffered from price fixing for a while and that seemed to make them unaffordable....

Was the chinese article ^ @FranJan written before the last month? Because capitol outflow of China has been a HUGE problem.....and part of the desperation, rise and fall now of their stock mkt.

An alternate hypothesis might be that a last ditch attempt is being made to stamp out "overseas" business and try and solidify an emerging industry on China's shores...and create a monopoly of sorts.....

Which could create problems for other manufactures if they remain hostile....or maybe there is blessing in disguise as even Cree, employs Chinese production, which could potentially lower manufacturing costs in a positive light....

Or has another Company behind the scenes made the play to wipe Vero's and make their own play in 6-12 months? Still lots of players out there...hell LG makes 24 watt versions for now...

It was posted Aug 6th and the B-lux announcement was less than a month ago so probably not.

Bottom line in my view of China is she likes to play both sides of the fence when it comes to economics. They've got their internal state run side and then the private and state run international side. Honglitronic recently announced the company will release 300 million non-public offering shares (LINK). Commies at home and capitalists on the road so to speak and they don't like losing so I always expect China to do the greediest thing, like Congress. And I think CREE long ago saw they had to be part of China to survive and that's why CREE nowadays is basically a Chinese company with more than half their workforce being based in China.

"Intense competition from government subsidized Chinese solar cell manufacturers has made it difficult for the Japanese manufacturer to profit."

http://www.ledinside.com/news/2014/12/chinese_government_halts_led_subsidies
"The Chinese government has issued massive subsidies to local LED manufacturers in the past, which led to the imbalanced oversupply situation, said an industry insider. Once the Chinese central and local governments cancel LED subsidies, Chinese LED manufacturers will find it difficult to survive."
Cheaters! :finger: :fire::cuss:That's why their economy is bullshit.

yeah I get what your saying and true up to a point... somehow there are still Chinese companies selling old led tech, despite being severely behind the time. take a scan of ebay and see what they are trying to dump.

LIGHT-GRID_500_8_inches1.jpg Do those huge dropoffs around the edges make sense? The corner values are under 200 and some zones are just 30% of the values of an adjacent zone.
I havent got a par meter but simple measures w my lux meter show way more even distribution. Would i observe those severe disparities if i was using a par meter.

EDIT: 8 inches WTF?
