12V requires quite a lot of amps for enough light, so low DC is not optimal. Also LEDs are current driven devices, i.e. they will be sensitive to voltage change

- JohnFen 4y agoLow-voltage doesn't necessarily mean 12V. I think it's anything below about 50, although lighting systems currently marketed as "low voltage" are usually 12 or 24 volts. The constant current thing is true, but that's not a terribly difficult problem.
- Dylan16807 4y agoIt's complicated. https://en.wikipedia.org/wiki/Low_voltage https://en.wikipedia.org/wiki/Low_voltage Depending on who you ask, the limit for low voltage DC might be 42 or 50 or maybe 60 or 120 or 1500.
