I am a big proponent of up lighting on architecture versus down lighting. I feel that up lighting draws attention to the structure you are lighting, while down lighting tends to draw attention to the light source. There are occasions when up lighting is not possible and the only option is down lighting.
This was the case for a client in Arlington, Virginia. They had recently remodeled their home from a traditional rambler to a beautiful craftsman style home. They ran into a security issue in the side of their house. This area was a parking spot for their SUV, and it was well traveled as they used that side of their house when they entertained to get to the back yard pool and patio. It was disconcerting to get out of their vehicle when it was so dark. The fact that the driveway went right up to the home limited the options for lighting.
They could install large, ugly spot lights on motion sensors. This is a practical way to light the area, but it has the feeling of a prison break out. We decided to install solid copper recessed led lights in the soffit. We used two prismatic lenses in order to diffuse and soften the light source. The flush mounted fixtures virtually disappear during the day. Once the sun sets, the lights give a warm glow of light in an otherwise dark area.
