A good quality 20W CFL has similar light output to a 100W incandescent lamp and should have a rated life at least six times as long.
Used for general and vertical illuminance as well as feature fixtures.
| Type of light | Distribution | Effect | Application |

Pendant up/downlight
|
1/ Upward diffused |
The uplight causes a wash of light on the ceiling – this creates the feeling of brightness and height in a space. And the indirect lighting provides diffused horizontal illumination. While the downlight provides higher diffused illumination on horizontal surfaces below. | This is often a feature fixture. It can be used for general illumination or more focused effects (eg. over a table or bench top). Solid shade offers shielding of lamp. |

Pendant up/downlight plus direct
|
1/ Upward diffused medium beam. |
The uplight causes a wash of light on the ceiling – this creates the feeling of brightness and height in a space. And the indirect lighting provides diffused horizontal illumination. While the downlight provides higher diffused illumination on horizontal surfaces below. Note: the shade allows light through that adds accent to a space, while increasing vertical illumination in the surrounding space. | This is often a feature fixture. It can be used for general illumination or more focused effects (eg. over a table or bench top). Direct light through the shade increases vertical illumination and adds accent to the space. |
|
Freestanding up/downlight
|
1/ Low height upward diffused medium beam. |
The uplight causes a wash of light on the ceiling – this creates the feeling of brightness and height in a space. And the indirect lighting provides diffused horizontal illumination. While the downlight provides higher diffused illumination on horizontal surfaces below. Its low lamp position makes the effect more localised, creating a sense of intimacy. | This is often a feature fixture. Since it is freestanding, its location is relatively flexible. It can be used for general illumination but is best for creating intimacy or focus. The solid shade allows the lamp to be shielded. Consider a light dedicated power socket so this can be controlled via a wall switch or lighting system. |

Freestanding up/downlight plus direct
|
1/ Low height upward diffused medium beam. 2/ Medium and diffused downlight. 3/ Direct diffused light. |
The uplight causes a wash of light on the ceiling – this creates the feeling of brightness and height in a space. And the indirect lighting also provides diffused horizontal illumination. While the downlight provides higher diffused illumination on horizontal surfaces below. Its low lamp position makes the effect more localised, creating a sense of intimacy. Note: the shade allows light through that adds accent to a space, while increasing vertical illumination in the surrounding space. | This is often a feature fixture.

1/ Low height upward diffused medium beam. 2/ Medium and diffused downlight. |
The uplight causes a wash of light on the ceiling – this creates the feeling of brightness and height in a space. And the indirect lighting also provides diffused horizontal illumination. While the downlight provides higher diffused illumination on horizontal surfaces below. Its low lamp position makes the effect more localised, creating a sense of intimacy. | This is often a feature fixture. It can be used for general illumination but is best for creating intimacy or focus. The solid shade allows the lamp to be shielded and reduces hot spots of light on adjacent walls. Consider a light dedicated power socket so this can be controlled via a wall switch or lighting system. |

Wall fitting (shielded)
|
Local medium and diffused downlight (can be adjustable). | The downlight provides higher localised illumination on horizontal surfaces below. Its low lamp position creates a sense of intimacy. While the shielded lamp reduces partner disturbance in bed. | This is mainly used for bedside situations but could also be used for task lighting in a home office. The solid shade shields the lamp and reduces hot spots of light on adjacent walls. Consider a light dedicated power socket so this can be controlled via a wall switch or lighting system. |
|
Wall fitting (diffused)
|
Low height, diffused down and direct light. | The downlight provides higher diffused illumination on horizontal surfaces below. While its low lamp position makes the effect more localised creating intimacy. Note: the shade allows light through that adds accent to a space, while increasing vertical illumination in the surrounding space. | This is mainly used for bedside situations but could also be used for task lighting in a home office.
