For Class 2, wet. I would check the price on landscape lighting cable. It might need protection from physical damage in some areas.
Some LEDs simply run on DC 12v DC power while some use a polarized ballast.
Some LED ballasts exceed the allowance of Class 2 and they can not be wired using limited energy wiring and these have to be wired the same way as fluorescent lamps.
"UL Class 2 drivers comply with standard UL1310, meaning output is considered safe to contact and no major safety protection is required at the LED / luminaire level. There is no risk of fire or electric shock. These drivers operate using less than 60 volts in dry applications, 30 volts in wet applications, less than 5 amps, and less than 100 watts. However, these limitations pose restrictions on the number of LEDs a Class 2 driver can operate.
UL Class 1 drivers have output ranges outside UL Class 2 designations. An LED Driver with a UL Class 1 rating has a high-voltage output and safety protection is required within the fixture. A Class 1 driver can accommodate more LEDs, making it more efficient than a Class 2 driver."
