1. Wired three Menards buildings to run on layout (transformer) power, instead of wall warts. I used: AC/DC to DC Buck Converter Step Down Modules 1.5 volt to 27 volt output. These things work great!! About $7 a piece, and you adjust the output to the 4.5 v DC needed by the Menards buildings.
"How To" write-up attached!!
Shipped 10 days from China. I have had 100% good service and 100% working units and LEDs from this outfit.
