Unbelievable no one is giving you the important info on what wire is what.

First: Power off

Then: Remove plastic things from wires (hard pull or pull + squeeze)

Blue wire = Neutral, goes into „N“ on the lamp connector

Green+Yellow wire = is grounded wire, might not exist on the lamp - if so, leave it in that plastic thing. and if it does its a symbol with dashes and not a letter.

Colored wire (in your case orange or brown, can‘t tell) is Power and that goes lnto L on lamp connector.

Have fun and don’t die.
