www.energy.govA luminaire can have a lower LER but do a better job of dis-tributing light to the task. 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

www.lightingassociates.orgOften, modern lamp technologies require special luminaire features. For example, T-8 lamps are 33% smaller in diameter than equivalent T-12 lamps, while producing nearly as many lumens. Because T-8 lamps are brighter per unit area, proper luminaire shielding is more critical than for T-12 lamps. Luminaire Components

Disadvantages: o Adds signal cable length; o Depending upon the surrounding terrain, guy wires may be needed to support the strain poles. 9.1.2 Traffic Signal Mast Arm Poles
