Lighting Power Densities

Requirements for Lighting Levels

quality lighting design using reasonably efficient lighting equipment. The limits are provided for whole buildings or individual space types as Lighting Power Densities (LPD) expressed in watts per square foot (W/ft2). The LPDs in Standard 90.1 are based on standard T8 lamps and electronic ballasts. Even

equipment densities relative to initial and longer-term electrical power capacities. Electrical capacity ranging from 30 watts to 70 watts per square foot for computer equipment is typically required. However, additional power is required for air conditioning, humidification, lighting, and uninterruptible power supply (UPS) and transformer losses.

Parking Structure Lighting Guide - Energy

Lighting Power Density (LPD) Lighting power density (LPD) is the total input power (i.e., including the driver or ballast) multiplied by the total number of luminaires divided by the area in which the equipment is installed. Many energy codes use this metric, however; it does not actually focus on energy. Energy is power multiplied by time, so ...

SBT-90 LEDs

Thermal management is critical in high power LED applications. With a thermal resistance from junction to heat sink of 0.5º C/W, Luminus SBT-90 LEDs have the lowest thermal resistance of any LED on the market. This allows the LED to be driven at higher current densities while maintaining a low junction temperature,
