Is the lamp low voltage or line voltage? I know they make cable with a built in wire for support, but I don't know specifics.

Welcome to the forums.

You would use 14-2 UF cable and a messenger wire. The messenger wire can be that 1/8" cable with the plastic coating on it. Sometimes it's called aircraft cable.

You can tie the UF to the messenger cable.

I would suggested going to an electrical wholesaler not (Walmart or Home Depot), and explain to them what you have, they should be able to help you.

To elaborate a little, you need more information such as the type of pole round, square, steel or wood. Maybe this will help and give you some idea what you’re looking to do. What you basically need is a couple of what we call insulators, you attach these to your poles to tie your cable off, you can use #10 solid wire to tie the cable off, but I wouldn’t suggest this unless you have done it before. I think today they make a cable cinches for this. The cable you need is 14/2 UF sunlight resistant cable no guide wire required. Basically that’s it except for what you need to make your connection at each end. Oh and make sure if you’re in traffic area to be high enough with cable.

Good luck

Neither are good sources of information. HD at least tries to be with varied success. Walmart doesn't even pretend. An old time hardware store might or might not be helpful.
no guide wire required
Please cite an authoritative source for that statement.
