Which power cable is suitable for parking lot lights and socket?

Since pipes are currently being installed for another purpose, I would like to preemptively thread the correct power cable for 5 connected parking lot lights as well as 1 outdoor socket. I do not have the lights yet, but they will likely be low-power lights so that the parking lot can be lightly illuminated. Which power cable do I need for this? Suitable for outdoor use. Thank you!

Rubber-sheathed underground cable, probably three times 1.5 sq mm. Buy it at the electrician's shop, that's where you'll get the right one.

Depending on the length of the cable, consider whether you need 3x2.5. If you want to be able to switch the lights individually in any way, 5x1.5 or 5x2.5 would be recommended.

Thank you Nordlys and Mycraft!

Depending on the length of the cable, consider whether you need 3x2.5. If you also want to be able to switch the lights individually somehow, 5x1.5 or 5x2.5 would be recommended.

Thank you for the tip! The plan is for the lower 3 lights, the upper 2 lights + 1 outdoor socket to be powered through a single power cable. Would you therefore recommend 5x2.5?

Depending on the length. If few watts, then 1.5 is sufficient.
