Polar Diagram of luminous intensity distribution
These provide a graphic representation of the distribution of light from a luminaire.
Often referred to as polar curves, they indicate the intensity, measured in candelas (cd)
per 1000 lumens.

The tables provided use luminaire Photometric data that has been measured and tested
in accordance with British Standard 5225 Parts 1 & 3 ‘Photometric Data for Luminaires’.
Additional photometric data can be provided upon request.
All data is also available in CIBSE TM14, EULUMDAT and
IES NA formats.

A complementary lighting design service is also available, to provide guidance and
recommendations and to ensure lighting solutions are tailored to customer
requirements. Supporting this service are the latest computer software facilities enabling
accurate predictions and performance checks to be carried out.
Performance cones indicate beam spread, ie. a narrow, medium or broad
beam of light. The illuminance values given (lux/Klm) are the maximum values
within the beam for horizontal planes at various distances below the
luminaire. The beam diameter, ie. the approximate size of the light coverage,
is also given. The cone widths are calculated for an illuminance at the edge of
the cone of 50% of the maximum. By spacing luminaires at the beam
diameter for the appropriate height, the combined effect of adjacent cones is
to produce an acceptable uniformity along the centre lines between
luminaires (figure 1).
