DETERMINATION OF THE MOST COST-EFFECTIVE METHOD OF CHOOSING THE TYPE OF LIGHT SOURCE AND WATTAGE FOR STREET LIGHTING-DESIGNED TO REDUCE CRIME.
Abstract
ANY LIGHTING SYSTEM SHOULD BE DESIGNED TO FURNISH A HIGH LEVEL OF VISIBILITY WITH A LOW LEVEL OF GLARE AND GOOD COLOR RENDITION. THE SYSTEM SHOULD BE INEXPENSIVE TO INSTALL AND MAINTAIN, YET DURABLE ENOUGH TO WITHSTAND THE VANDALS AND RAVAGES OF TIME THAT TAKE THEIR TOLL ON MUNICIPAL EQUIPMENT. THE AUTHOR DISCUSSES FOUR LIGHT SOURCES - FLUORESCENT, SODIUM-VAPOR, MERCURY VAPOR, AND METAL HALIDE, AND CONCLUDES THAT SODIUM VAPOR LIGHT SOURCES ARE THE MOST ECONOMICAL AND EFFICIENT.
