1. AdequateilluminanceThe performance of the human eye largely depends on the level of
illuminance in the visual field.
As illuminance increases, motivation and overall performance are
also enhanced, while the tendency to make mistakes declines.
Rothschild,Dubai
10 Rules for good lighting

2. Harmoniousdistributionofluminance
A balanced distribution of luminance on the various surfaces makes
an interior visually interesting.
Inadequate or excessive contrast, on the other hand, causes visual
strain and fatigue..

3. AdequateglarecontrolGlare in an interior is rarely so severe that visual performance is
significantly reduced, but it can be irritating and cause eye strain.

10 Rules for good lighting

4. Goodcontrastrendition
Contrast is necessary for the human eye to be able to discriminate
between objects and their background.
A lighting system with good contrast rendition does not cause
reflected glare even on shiny surfaces and documents, so that
text is easy to read even on glossy paper.

5. TherightdirectionofincidenceThe direction of incidence of light is important for Contrast
Rendition, as it determines the angle at which any reflections can
be seen.
It influences the distribution of light and shadow, which is the key to
threedimensional vision on the one hand, and can be irritating
or even dangerous in the case of heavy shadows, on the other.
Atlantis,Ljubljana
10 Rules for good lighting

6. Pleasantshadowconditions
Shadows reinforce threedimensional vision and facilitate
orientation. Good shadow conditions are the product of an
effective combination of diffuse light and directed light.

7. Suitablecolor
appearance
In the course of the day the light appearance of natural daylightchanges. Artificial light can also be produced with different lightappearances or colors so as to support various lighting functionsand moods.
Arki,Dubai

8. Naturalcolorrendition
Only the spectral colors that are contained in the incident light can
be reflected by an object and perceived by the human eye.
Color Rendition is a measure of the ability of an artificial light source
to show the natural colors of an object.

9. EffectivelightingatmosphereLight affects our mood and feeling of wellbeing. The result is a
subjective, more or less unconscious impression of an interior
and its light. This aspect of good lighting planning also requires a
degree of experience with the interplay of the various factors
and a fine feeling for good light.
Mediahouse,Stavanger,Norway

10. Efficientenergyconsumption
A basic requirement for modern lighting planning is the careful and
economical use of energy. The various solutions now available
relate not only to new installations, however, but also to
retrofitting and refurbishing old and inefficient systems.
