There are three types of lighting that are used in a home: Ambient, Task, and Accent lighting. All are important to create a happily lit home.
Ambient lighting provides overall lighting for a space, or general lighting. It is intended to light the whole space, and minimize glare & shadow. Usually, this is seen as a main ceiling light in a bedroom, or a chandelier in a dining room. Recessed lighitng is also being utilized to light up rooms like kitchens and lower level family rooms.
Task lighting is exactly that – it specifically lights up the area where a task is done. For instance, utilizing undercabinet lighting over your kitchen counters, an adjustable desk lamp to light up paperwork, or track lighting to spotlight a craft table.
Accent lighting is a great way to draw attention to focal points in a room. It also is used to create drama and intruige. This can be achieved by using a small adjustable recessed to spotlight art, or track lighting in front of a fireplace to spotlight some stonework.
