Lighting power density unit
WebUnits: Power: Energy of light per unit time, such as the energy delivered by a laser beam. W or J/s: Energy: Potential energy stored in electromagnetic radiation, found by integrating power with respect to time. J: Power Density: Power per unit area, also known as irradiance. W/cm 2: Energy Density: Energy per unit area, also known as fluence. WebLighting Power Density Areas (LPD Areas) calculate the lighting power density based on the number of luminaires within a user-defined polygon. Lighting power density is defined as watts per area, where area is dictated by the current display units (ft. or m) in AGi32.
