My house was built in 2018. The smoke alarms are low voltage. I remember the electrician, who installed them, told me they are DC.

Thermostats and doorbells are low-voltage AC. The transformer is standard. If you can find 24-volt AC lights, an open-minded electrician should be able to figure it out.

Related: My old house built in the 1960s had an intercom system that was ripped out by a previous owner. I found a warm transformer attached to a bare bulb light socket in the basement with nothing else running from it. I happily removed it.

LEDs will flicker (worse than old-school fluorescent lights did) when directly connected to 60Hz AC.
