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.
Lumens to watts calculation formula. Energy saving lamps have high luminous efficacy (more lumens per watt). The power P in watts (W) is equal to the luminous flux Ï V in lumens (lm), divided by the luminous efficacy Î· in lumens per watt (lm/W): P (W) = Ï V(lm) / Î· (lm/W).
