Adding lights as decorative elements helps set a mood in a space. Provided that general lighting is already installed using lights instead of wall art can be a decorative way to provide ambient lighting.
This kitchen features several layers of light: The recessed cans provide overhead illumination the pendant lights above the island illuminate the workspace and undercabinet area and above-cabinet accent lighting gives the space a burst of savvy style.
If your cabinets don't go to the ceiling consider adding lights above the cabinets. Using a more powerful light source such as a T5 fluorescent increases the reflectivity of the ceiling thereby increasing the light in the room. While increasing light levels is important it is equally important to minimize glare. Use matte finishes to reduce light flares and glare.
