| Ambient Lighting
Ambient light is the general background light all around us it softens contrasts between brightly  lighted task areas and the surrounding areas. Fluorescent, halogen or incandescent recessed lights in the ceiling cast light directly downward and outward. Wall sconces and halogen torchiere floor lamps shine their light up at the ceiling, which then reflects the light throughout the room. Wall washers cast their light against the wall, which in turn provide ambient light without creating a glare. Table lamps with translucent lamp shades cast soft light in a room. In many applications, it is desirable to have the major ambient light source dimmable.
