This article exposes data from public lighting used on an avenue in Recife, Pernambuco. It sought to determine indicators of energy savings and environmental impact of lighting technologies using Light Emitting Diode (LED) in use related to the sodium vapor used previously. Electricity expenditure and waste quantification were observed. The case study was carried out over an 8 km stretch and highlighted the importance of meeting current legal standards. It was shown that, in the same period, 2.27 times fewer lamps were used and waste fell by 64%. Savings were made: energy (282,852 kWh), in annual expenses (R$ 130,111.76), representing a reduction of 38.47%. The data analyzed in this work indicate that LED lighting is the most appropriate technology, at the moment, to reduce costs and preserve the environment.
