LIGHTING MAKES A SAFE TUNNEL SAFER

THE PRUDENTIAL TUNNEL IN BOSTON, WHICH STRETCHES SOME 2,000 FEET UNDER THE CITYS NEW PRUDENTIAL CENTER, WAS THE FIRST TO UTILIZE A RECENTLY-INTRODUCED MULTI-LAMP FLUORESCENT LIGHTING SYSTEM. SOME 1180 NEW FLUORESCENT LUMINAIRES ILLUMINATE THE TUNNEL AREA. ON THE REMAINDER OF THE 12-MILE ROADWAY, 342 FIXTURES MOUNTED ON TWIN-ARM STANDARDS SPACED 175 FEET APART AND MOUNTED IN THE ROADWAY MEDIAN, LIGHT THE FOUR TRAFFIC LANES ON EITHER SIDE. SINGLE-ARM STANDARDS LIGHT ALL RAMPS, AT INTERCHANGES AND TOLL BOOTHS, FLOODLIGHTS SUPPLEMENT THESE ROADWAY LUMINAIRES. THE TOTAL SYSTEM PRODUCES A COMBINATION BLEND THAT RESULTS IN AN OUTSTANDING LIGHTING EFFECT. ALL OF THE TUNNEL LIGHTING GOES ON AND OFF AUTOMATICALLY. THE LIGHTING INTENSITY AT ANY ONE TIME DEPENDS ON THE NATURAL LIGHT OUTSIDE THE TUNNEL AS WELL AS THE AMOUNT OF TRAFFIC INSIDE. THIS GIVES MOTORISTS MAXIMUM SEEABILITY WITH A MINIMUM OF GLARE. /AUTHOR/ FLUORESCENT LIGHTING SYSTEM.
