Mr. Mark Casey <br />January 6, 2017 <br />Page 2 <br /> <br /> <br /> <br />When LED’s first came out the color temperatures were in the 5000k-6000k range, which gave off a <br />bluish tone. Advances in the industries have improved the color and efficiencies. The majority of street <br />lights installed by MnDOT today are 4000k color intensity. Attached to this report are pictures of 3000k <br />and 4000k lights that are installed in the City of Minneapolis. In one of the photos of the 4000k overhead <br />lights, the lower lantern lights are HPS lights. It is hard to tell the difference in these photos but the 3000k <br />lights are a bit ‘softer’ light. These photos were taken on N. Washington Ave at 9th Avenue North looking <br />north (4000k) and south (3000k). There is virtually no price difference between the different heat intensity <br />fixtures for this application. <br /> <br />The types and intensity of the LED fixtures were chosen to replicate the lighting that currently exists along <br />these segments. As noted in the first paragraph, 3000k LED lights will be used in the lantern style lights <br />and 4000k LED lights will be used in the overhead lights. <br /> <br />Quotes were secured from three (3) separate electrical contractors for the removal and installation of the <br />new light poles and heads. The estimated costs are as follows: <br /> <br /> City of St. Anthony City of New Brighton <br /> Materials Installation Cost Cost <br />Segment 1 $104,129 $15,465 $119,594 $0 <br />Segment 2 $58,020 $14,350 $36,185 $36,185 <br />Segment 3 $118,080 $24,660 $0 $142,740 <br /> TOTAL $155,779 $178,925 <br /> <br /> <br /> <br /> <br /> <br /> <br />
