600W Heavy Duty Outdoor Transformer with Built-in Timer & Photocell - Weatherproof Black Metal Housing for Landscape Lighting, Garden Lights, and Pathway Illumination

This unit worked perfect and even has a solar sensor to activate the lights when sun goes down and off when sun comes up. I will its a little heavy and challenging to mount on the side wall of the house. So, prepare yourself to have a hammer drill and proper strength hardware to mount the heavy transformer.
