2.3.6 Spectral

distribution

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/(m2 x 5 nm x 1000 lx)

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:

Illuminance E (measured) x (y-axis value)

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® and LUMILUX® DE

LUXE lamps can be found in the latest edition of the Lighting Programme.
