as one who got some when our" jorge" buddy was posting..at 34 w per they [J130 B] did a good job for me..

of course i can only speak from growing experience.. i admit to not being a real tech
some quick napkin calculations based off the data sheet http://www.nichia.co.jp/en/product/led_product_data.html?type='NFDLJ130B-V1' show impressive performance when under driven in the 700 to 1000 ma range, exceeding 180+ lumens per watt

nichia has released a version 2 of these chips with a small improvement, but the usa distributor doesn't have any version 2 chips.

Looking for maximum 28V COB or two smaller ones to fill up MW HLG-240H-C1050 driver. Right now I have 210V on it - 6x Citizen 1212.
Over voltage protection for this driver is 250-270V - can I mount one more Citizen 1212 on it? 210V + 35V = 245V ?

You don't want to go over 238 VDC with that driver. It will start cutting current. Over voltage is a shutoff condition. You may could add 1 24 volt led. QB 120 would work lol.

Always look at constant current range. That is what the driver will give it's full current at. Anything over and it will drop current.

Have you actually tested the voltage as well? Check at start up and also after stabilization (around an hour).

Looking for a smaller and cheaper option, just to fill existing light.

viss led dispaly
VISS has always been a product-driven company since its establishment in 2004, particularly specializing in rental LED displays. A company's gene is determined by its founder, and Tyson Zhong, the founder of VISS, is one of the very few LED company owners who is truly professional and enjoys spending most of his time making his products not just workable, but really user friendly and aesthetic. If you don't know
this man,you probably don't know the industry history of rental LED displays in China.

In 2006, when almost all other manufacturers were still making heavy and clumsy traditional LED cabinets with DIP lamps, VISS brought to the market mesh and strip screens, for example, 37.5mm mesh screen for staging applications, 2.9kg per panel, and 25mm SMD strip screen for both indoor and outdoor rental applications. In 2008, VISS initiated LED dance floor to the market, which was a fresh air to the rental world when most people didn't even know how to make a rental display. In 2010, VISS launched a unique mesh product, SE Series, which is still a very popular product until today. Because VISS focuses on rental LED displays, it is a leader in this market segment.

Some years later, VISS was eventually surrounded by similar products as peer companies would learn and catch up,and now,there are more than enough rental products in the market. So the question is, what is the difference between VISS's products and other rental products? The answer is, everybody can make their products work, but VISS makes its products user friendly and aesthetic. And these are great add-on values VISS always offers to higher end clients.

Some people think LED displays are just a tool to make money. No one will deny it, but on top of that, we believe a great event deserves to have great screens which do not just look beautiful in the front, but also look so attractive on the back that the end users sincerely love to have them in the event. We believe the rental crew deserves to have screens that make the installation and service genuinely easier and quicker in the real world not in the PowerPiont, because this is a stressful job. We believe the market deserves to have the option of products that offer not only functionality, but more importantly, user experience, after all, people are different, and what we choose makes us who we are.
So where's the grow light?
Come to think of it, it is sitting in the LR. Upcoming tech is basically a big flat screen TV & the channels are 27k-65k w/ options to add photosynthesis driving colors.
Wouldn't that be something!

I think the PCB is made, and dies printed in china and the phosphor is applied in the US, or the other way round. What source are you wanting to buy from on Alibaba ?

And why not go with Vero's better performance and has a scannable bar-code on each chip to verify its authenticity. It is not an easy chip to counterfeit anyway.

A Corporation may produce or have produced LEDs in China or elsewhere under closely qc'd conditions assuring top quality and performance or they or others may buy the cheaper alternative maybe from the same seller even. They might even arrange for identical packaging. Reputation and integrity is everything!
