Analysis of energy saving in industrial LED lighting: A case study

Abstract

The present study shows the economic savings and environmental advantages of LED lighting technology for industrial applications. For this purpose a case study in which metal halide lights were replaced with LED lights has been performed. For validating the replacement of 400W metal halide by 200W LED luminaires, there have been performed lighting simulations and field measurements by lux meter. The results indicate that both luminaires are comparable, obtaining significant energy savings close to 50%. This research demonstrates that LED lighting technology offers high performance lighting solutions that optimize energy saving, while reducing maintenance costs, with a significantly lower total cost of ownership (TCO), increasing the life span of the luminaires. From the environmental point of view it means a significant reduction in CO2 emissions and the disposal of toxic waste such as mercury.
