...That buck converter board you are using looks like it should be good for at least 1 amp load if its an LM2596.

Since those LED's would only draw 5 ma or so each, one board will power a couple of hundred likely.

That looks like an RT8272 module still more than adequate to power all Joe's lamp posts and then some!

IIRC the "problem" with this module is the max input voltage is 24V DC.  So even with bridge-rectifier, not wise to use this for passenger-car lighting or other rolling-stock powered from AC command-level track voltage.
