2.3.6 Spectral
distribution
Light colours
Colour 60 – Red
Colour 67 – Blue
The relative spectral power distribution is determined mainly by the light colour, whe-
reas the different models and wattages have a negligible effect.
The spectral distributions shown below are therefore typical of all OSRAM DULUX
lamps for the relevant light colour.
y axis: mW/(m
x axis: wavelength in nanometres
Notes on the charts:
The spectral irradiance distributions refer to an illuminance of 1000 lx. The advantage
here is that the absolute values of any illuminance can be found simply by dividing by
1000 lx:
The spectral intensities are condensed into wavelength ranges of 5 nanometres. In
other words, irrespective of the actual distributions, the values given have been integra-
ted over 5 nm. This corresponds to the standard applied to all calculations of conse-
quential results (such as colour and colour rendering).
The spectral power distribution of OSRAM DULUX LUMILUX
LUXE lamps can be found in the latest edition of the Lighting Programme.
