Hello - I am building an LED lighting application using a COB LED light similar to this one: https://www.digikey.com/en/products/detail/creeled-inc/CMT1420-0000-00PN0U0A30G/9998303.
I've been troubleshooting why the LED light is not turning on when I connect it to power and it seems the LED light itself is broken. As you can see from the picture, there are positive and negative terminal pads on the COB LED. I used my multimeter (switched to Ohm mode to measure resistance) and when I connected the multimeter leads to the COB LED light, it showed OL or overlimit resistance even at the highest Ohm measurement level (20 Mega Ohms).
I believe this means there is no connection between the positive and negative pads of the LED light and therefore the LED light is defunct. Is my reasoning correct? It's strange since this is a brand new COB LED light.
