Discuss COBs or any other types of LEDs that don’t fit the other categories (Cree, Citizen, Migro, etc.).

I apologize if this topic has been covered somewhere earlier but I have some 6500k 150 watt 7x5 inch cobs that run on 220/240. There are no push Connectors like there are on the quantum boards. itself so they have to be soldered and im finding it very difficult to get the solder to stick. Is there a trick to it?

First, tin the COB. Tin the cable. Then try. Make sure your soldering iron is very hot.

A little flux on the contact might help. Worked on my thrives strips.
