Although often thought of as primarily an outdoor accoutrement lanterns are useful indoors for adding an extra light to areas such as bathrooms especially when a calming glow is desired for a relaxing mood. Plus a glow coming from below eye level can perfectly balance an overhead light.
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.
Bright idea for unexpected lighting: Look for opportunities to install light fixtures in alcoves tray ceilings and wall niches to trace interesting lines. Notice the hidden lights in the ceiling alcove above the cylindrical fireplace mantel here.
