The present study aimed to present the results that a supermarket obtained in view of the proposal to replace fluorescent lamps with LED lamps. The methodology used was based on the comparison between the types of lamps mentioned with a quantitative approach based on bibliographic, documentary research and observation for data collection, in addition to calculating the feasibility and return on investment through the methods of Net Present Value (NPV), equivalent uniform cost and payback. The results found confirm the feasibility of replacing the lamps with a 15-month payback time, causing a monthly savings of R $ 280.00 in the electric bill and a 52.6% reduction in the emission of carbon dioxide indirect compared to fluorescent lamps.
