Task lighting is what you get from lighting a chair or a worktop. It sounds like it should only be employed in the kitchen or in a study, but when you think about it, there are tasks of some kind or another to do in all rooms, and being able to see well to carry out those tasks is important. Task lighting needs to be bright and targeted so that it is restricted to a particular area and doesn’t spill out elsewhere. Reflective shading can be used to achieve this, but it wastes the energy consumed by the light. It is far better if the light is directional. An example of this would be study desk lamps. Being low and shaded, they cast the light down on to the desktop without it spilling around the room or up into your eyes.
