Lighting design is all about the strategic placement of light and matching the perfect light source to its intended function. Indirect lighting pulls focus adds texture and layers the sight line.
All-around lighting includes general lighting and natural light. You want to ensure that at any time of day there is enough light for everyone to effectively use the space without incident and that any dark areas are minimized.
Although floor lamps and table lamps obviously differ in their typical size and placement both have the ability to add gentle task lighting for reading while also infusing a general glow wherever they stand targeting anywhere from the center of a room (say on a sofa table) to a dim corner.
