    I used these to repair a LED lamp and they work fine. Because I was in a hurry the first replacement I ordered from a portal but it died on the first day. These two from Banggood work fine and are still functional. Again I learned that it pays to wait a bit for the shipment.

    Very bright and the power consumption says about 5W even at 9 volts - eventually rebuy this...

    Unfortunately, there's no resistor limiting the current to the diode.

    Attenzione: Il COB non può essere collegato direttamente ad una batteria o ad un alimentatore da 12V perché non ha una resistenza interna per la limitazione della corrente. Per una corretto funzionamento può essere collegato a un alimentatore da 12V con in serie una resistenza da 8-10 ohm 2W oppure ad un alimentatore a corrente costante (ad es 350 mA). Con 350 mA la tensione ai capi del COB è di circa 9V e la potenza è di circa 3W.

    specifications are 9-12V, but when I connected at 11.7V, 2 LEDs burned out and the plate started to heat up very fast, in 15 sec I couldn't hold it in my hand. So definitely it is not made for 12V!

    The item is working well. However, installation was a kind of tricky and keeps me from giving an overall 5 star rating. The terminals are not + - and +- as shown on pictures and which I'd consider being the normal setup. Instead these are ++ and on the opposite side you will find -- / see the pictures with the received and built-in COB chip vs. the original COB chip Most light fixtures are looking for +- next to each other. Thereto you will be required to modify the connecting wires for this item most likely.

    Neutral color temp seems ok as daylight approximation. Good light and fits in many places. I use these as video light source for my full 360 degree Xiaomi camera, but only at ca. 1W per lamp to avoid heating. They will last forever in this use :-) Will need a heat sink if run on full power but lights nicely with lower settings too.
