Battery Power for 12v Dollhouse Lighting

I had gotten lighting from somewhere else (can't remember where) and wanted a power supply to plug into, this was exactly what I needed. My installation job was NOT expert as it was my first time doing anything like this, but this wiring pack was VERY easy to work with, literally just "plug and play". If you are intimidated by the wiring and powering side of dollhouse lighting, this is a great way to experiment with it in my opinion!
