Lets be frank. New York has stringent electrical codes. ALWAYS for the health and safety of others USE THE NEWEST CODES and Regulations. Local inspectors love to see people go to code. We have electrical codes for a reason. The reason,...the dead bodies of adults, children, animals and destroyed property.
The latest LED still uses amps/watts/voltage. Enough to easily kill and destroy. It is this simple. Even here on the family farms where we can do things differently in some respects, we still strive for code. It does not cost more and is safe. Its that simple. If electrical is to code, you cant get sued either.
In my residential I insist on 12 gauge still in typical 15/20 amp circuts. Why? Wires over burdened will get hot. They get warm during normal use. Especially in certain weather conditions. I would rather have the safe factor! I insist on top grade circuit panels also. Why? There are vast differences between builder grade and best grade electrical panels. It does not cost that much to have better wires, electrical panels, new drops and fixtures appropriate for the situation.
Also, most LED lights and fixtures are made good enough to work.....good enough...means you must be better.
Now for the kicker.
If you are considering low voltage remember it still can kill you. Use appropriately. There is code for low voltage and different applications.
Wire if for a lifetime and the next person who will live in the situation. Talk to your local inspectors and get a good rep. Get coded. Get it right. Good luck.
