I need to add a PIR sensor to a 10w led wall light. It is under the car parking area and does not get wet. Would this cable be suitable?

The cable itself is well within its ratings on a 10W LED so that would be no issue.

 

It is considered poor practice (or even illegal) to use a green or green/yellow wire as a current carrying conductor even with sleeving on the ends.

 

Unlike the Shopee illustration most of the 3 core flex I've seen here actually has black, grey and brown conductors so the above doesnt apply.

 

So, like many things here it's Up2U.

 

I have found the correct wire - VAF-G. Quite expensive at 46bt per m.

You should have read @Crossy post first. There is nothing wrong with the spec of the cable you suggested, only the wrong color of wire.
Just look for a cable with black, grey brown wires
