Wall washing is ideal for an all-encompassing, non-focused spread of light, and can reduce the number of track heads required. Wall wash track heads frequently feature energy-efficient fluorescent bulbs as an added bonus. Make sure that a wall wash fixture is placed at a sufficient distance from the wall to avoid unattractive shadows on the wall.
For more focused accent lighting, use adjustable spot light track heads. These fixtures can provide a higher level of light on a specific area. Angle the track heads at approximately 30° in order to minimize glare and reflection.
