coordinates
tolerance fields
Chromaticity coordinate tolerance fields are ellipses in the chromaticity table which
represent the permissible range for the relevant light colour.
The tolerances are five threshold units for all light colours (LUMILUX
LUXE).
A threshold unit represents the minimum perceivable difference in colour between two
lamps (see also IEC 60901 and IEC 60081).

are ideal for most applications (including office and shop lighting, hotel and restaurant
lighting, living rooms and outdoors). In places where colour rendering is a particular
important factor (art galleries, museums, laboratories and graphical trades, for exam-
ple), OSRAM DULUX
As group 1A lamps, these offer the best colour rendering. However, because their
luminous flux is lower than their LUMILUX
achieve the same lighting level.
Ultimately, the choice of light colour depends on the specific application, room con-
ditions and personal preference.

1) Lamps with chromaticity coordinates that do not lie in the vicinity of the reference radiators (Judd lines; see
CIE calculation method) cannot, by definition, be assigned a colour temperature and hence cannot be assigned
a colour rendering index.
