THE DESIGN AND SPECIFICATION OF HIGH MAST LIGHTING

THIS PAPER IS IN THREE PARTS. THE FIRST, BY CROWTHER, DEALS WITH THE DESIGN OF THE MASTS THEMSELVES. HEIGHTS AT PRESENT ARE USUALLY BETWEEN 60 FT AND 120 FT. DETAILS ARE GIVEN OF WIND VELOCITIES, LOAD FACTOR, COLUMN DEFLECTION, AND WIND EXCITATION. APPEARANCE DESIGN OF MASTS AND LANTERN CLUSTERS IS A SOURCE OF CONTROVERSY. RAISING AND LOWERING GEAR AND MAINTENANCE GENERALLY ARE DISCUSSED. PART II, BY JORDAN, IS ON LIGHTING DESIGN. SINCE THE LAMP LUMENS MAY BE 200,000 OR MORE FOR ONE MAST, A COMPLETE CUT-OFF IS NECESSARY. THE AUTHOR ARGUES THAT THE 1,000 W COLOR- CORRECTED MERCURY LAMP HAS ADVANTAGES OVER SODIUM SOURCES. THE PLANNING OF LIGHTING FOR A MULTI-LEVEL JUNCTION IS DESCRIBED IN DETAIL. PART III, BY COX, IS A FULL ACCOUNT OF THE SEVERN BRIDGE HIGH MAST INSTALLATION AND THE PROPOSALS FOR ITS MAINTENANCE. /AUTHOR/
