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.
The most common use of up lighting is in a recessed cove around the top perimeter of a room. To maximize light output use a T5 fluorescent or LED light source that will wash the ceiling with light. This helps to create a brighter ceiling that bounces and reflects light throughout the space without glare. Combine this with lots of natural daylight to increase the overall light levels in a room.
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.
