Lighting Power Density (LPD)

Lighting Power Density (LPD) is the electrical load of lighting per area lit, measured in watts per square foot. 


Many spaces are overlit (i.e., LPD too high), leading to wasted energy and potential occupant discomfort. Getting LDP right is therefore critical to resolving multiple lighting challenges.
