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.
Downlighting is just that: lighting that shines down to illuminate a space. Down lighting can sometimes be referred to as general lighting. Once it was simply the only light source in a room — that single fixture in the middle of the ceiling. If this is your only option placement and quantity of fixtures are the keys to attaining a balanced lighting level while reducing dark corners. Pot lights are also considered downlighting.
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.
