Lighting power density (LPD) is defined as the total amount of lighting power, in watts, provided to a given floor area, in square feet. A conventional general office lighting design has an LPD around 1.2 W/ft2, while an optimized design can be 0.8 W/ft2 or below.
The intensity varies with the distance from the source and the power of the source. Power is a property of the light source that describes the rate at which light energy is emitted by the source. Power is often expressed in units of watts.Table 1 shows the dependence of intensity (I) upon the distance (r) from a 60-watt light bulb.Numbers are rounded to the second decimal place. 1996-2012 The Physics Classroom, All rights reserved. Light Intensity The term intensity is used to describe the rate at which light spreads over a surface of a given area some distance from a source.
