D4 LED Post Top Retrofit – Case Study
D4 LED Post Top Retrofit – Case Study
City of Chicago – The City of Chicago selected our D4 LED Post Top Retrofit to replace 100w high pressure sodium and a competing LED product at twice the wattage. The City saves 77% over the high pressure sodium and 43% over the competing LED product in energy savings. Plus, this will reduce maintenance costs by over 75% and provides the city with a rich white light and excellent color rendering, mercury free.
