Depends on the voltage. Some LED systems are designed to keep the DC under 50 volts, so almost anything is compliant. That is, the LEDs don't affect the cable selection, environmental and cost factors do. One company I know designed their product to use CAT5 or equivalent.
Do you have a specific system in mind?

Low voltage cable as used for landscape lighting can be used, but if run inside walls (or dead spaces in cabinets?) would have to be rated for concealed use. (CL type)

Thanks for your replies.
The customer has decided to install the LED system and is installing 2 wire thermostat cable for the DC side of the LED drivers. It just looks funny to see thermostat cable feeding LED lights.
I guess there is always first time for everything and I will probably get used to it.

You are required to use a Chapter 3 method unless the power supply is listed as Class 2.
Even if the supply is listed as Class 2 using small gauge wire such as thermostat wire is a bad idea. The voltage drop is going to greatly effect the lighting performance. There is 10 times as much current on a 12 volt lighting system as there is for the same system operating at 120 volts.

I understand the current ratio of the high to low voltage.

I used FPL #14 cable just due to having some left over from a fire alarm job.

How would this guidance change if this was in NYC.
I'm being told this has to be all 12/2 or 12/4 (for 4 Ch LED tape) BX which seems pretty intense for LED lights.
