Relative Lighting Power Density
The figure above compares relative power density for various lighting conditions in units of Watts
per square meter (W/m
2
). The reference standard condition is 1 Sun and is equal to 1000 Watts
per square meter of sunlight irradiance at a constant 25°C cell temperature and at 1.5 Air Mass
(Air Mass stands for a well defined light spectrum which appears if the sunlight goes through the
earth’s athmosphere at a defined angle).
As the chart clearly shows, the power density of typical indoor lighting is dramatically lower than
that of sunlight. Not only is irradiance from indirect and artificial light lower; the spectrum is also
narrower. In typical Office Space lighting with a spectrum produced from incandescent or halogen
light bulbs, the power output may be roughly 100 times less than bright sunlight. It may be 200
to 500 times less with fluorescent lighting due to the further limited spectrum.
