    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).

    Hello, Speaking of QB 120's....When will more 3000k be arriving ?

    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!

    so, guys, in the end, is CREE producing their cobs in China ? are the cxb's 3590 listed in their alibaba shops fake stuff ?

    DankaDank Well-Known Member

    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!
