    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.
