You probably don't think buying a lighting fixture for a room is all that complicated. It isn't. However, it does require you to consider which types of lighting you may need. According to the Lighting Association, there are three types:
General lighting. By far the most common, this is the type of lighting that is designed to create a functional brightness that spreads throughout a room. A good example is a main ceiling light.
Task lighting. As the name implies, this type provides extra light needed for a specific task, such as working at a desk or chopping onions on a kitchen countertop. A bedside lamp used for reading is another example of task lighting.
Accent lighting. This type is designed to set off a particular feature of a room, such as a painting. It creates some practical light, but its main purpose is to add to the overall decor.
When choosing lighting for a room, it's important to consider these three types. First, decide how best to light the space generally. Then think about any special lighting you might need for specific functions, such as reading. Finally, consider how accent lighting might add to the overall look.
