Flood light led chip replace (with different size LED COB)

This video is simple and general instruction how to change led chip (LED COB) to the flood light. This repair instruction can be used in almost any size and type of flood lights, no matter if there is one or more chips.
Typically led drivers (power supplies) are not the problem with these led flood lights, but it's wise to diagnose those before changing the led chip. Led chip can be different size as I show in the video. Most important thing is that Power rate and voltage are matching the led drivers specs.
Device I'm working on, is 100W flood light, used to light outdoor area around the warehouse.
Side note:
I'm a mechanical engineer, but what it comes to electronics, I'm mostly self-learned. Do not try to fix your electronic devices if you're not sure what you're doing. If you handle electrical devices carelessly, you may get electrical shock or cause malfunction to the device.
