There's something off about LED bulbs

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 changes (even with a current limiting resistor)

Low-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.

It's complicated. 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.
