It’s important to understand that even on a sunny summer day natural light from a single window is not always sufficient to thoroughly light a room and of course this is especially true come nighttime. Additional light sources near your window will allow you to subtly fill out the light scheme and achieve a balance so the space feels beautiful at any time.
Sconces come in many forms from artistic and ornate to sleek and simple and can hold just one bulb or many. Single-bulb sconces that are spread farther apart will add light around eye level for more even brightness. For the total elimination of shadows pairing two-light fixtures spaced closer together will achieve a salon level of clarity.
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.
