3 Basic Types of Lighting

One room can serve multiple purposes. It can be a place where you can relax, work on the computer, do arts and crafts, cook, share a meal with friends, and much more… This is why lighting features need to correspond to the setting or application of the room.

“The best advice I can offer is the following: no matter what you do, or what you hope to accomplish, always install three types of lighting in a room,” says Patricia Rizzo, of the Lighting Research Center . People often expect a single source of light to meet all their needs. Yet, each of the three types of lighting has a particular function to fulfill specific needs, which are:

  • Ambient lighting
  • Task lighting
  • Accent lighting

Ambient Indoor Lighting

General or ambient lighting is intended to light up a room in its entirety. It provides a uniform level of illumination throughout the space independently of other lighting sources.

Moreover, its purpose is to ensure safe and easy traffic, as well as to create an overview of the room. The ambient light ‘bounces’ off the walls to illuminate as much space as possible.

Types of fixtures that can provide general ambient indoor lighting:

  • Chandelier
  • Ceiling mounted fixture
  • Wall-mounted fixture
  • Traditional recessed fixtures and / or LED downlights
  • Track light
  • Floor lamp
  • Table lamp

Ambient Outdoor Lighting

Outdoor lighting is usually installed in order to ensure visibility and increase security around a building. It is also recommended to light up the exterior of the building, entrances and stairs to reduce and perhaps eliminate the risk of injury that can occur when entering and leaving the building.

Types of fixtures that provide ambient outdoor lighting:

  • Spotlight
  • Hanging fixture
  • Garage and canopy lighting
  • Post lantern
  • Wall lighting
  • Recessed fixture used in overhanging structures

Task Lighting

Task lighting illuminates the tasks a person carries out in a given space such as reading, cooking, computer work. A brighter light is required in a smaller focal point of the room for these sorts of tasks.

For a more pleasant illumination, it is often best to avoid harsh lights or lighting that casts troublesome shadows. It is also practical to install a single switch for focal lighting, independent from the room’s overall lighting switch.

Types of Fixtures that Provide Task Lighting:

  • Directional gimbal recessed fixture or downlight
  • Pendant lighting
  • Slim line bar and undercabinet
  • Tape and extrusion
  • Portable or desk lamp

Accent Lighting

Accent lighting is used mainly to focus on a specific point of interest or to achieve a desired effect. This type of lighting gives the impression of a larger room. It is more frequently used to highlight an architectural feature, a plant (in outdoor layout), a sculpture, or a collection of objects.

As a general rule, effective accent lighting requires the installation of three times more light on the focal point than ambient lighting generally provides.

Types of Fixtures that Provide Accent Lighting:

  • Track light
  • Slim line bar and undercabinet
  • Tape and extrusion
  • Directional recessed fixture or downlight
  • Wall-mounted fixtures

In short…

We often start designing our lighting plan with ambient lighting and then go on to identifying the areas where there will be a need for accent lighting. When selecting the different types of lighting you will use in your situation, it is generally better to go from generic to specific.

However, when multiple specific tasks are performed in a room (a jewelry store, for example) or when there are several points to highlight (such as a museum or an art gallery), it is best to start a lighting plan with accent lighting. Therefore, it is essential to know the purpose of a room before starting the development!
