This obviously represents a huge benefit in terms of time and money when renewing existing facilities, acting in historical areas or buildings and even for new infrastructure. From economic and environmental points of view, the benefits are clear in terms of energy savings: less consumption, lower costs and less CO\({}_{2}\) emissions, in addition to the benefits obtained from optimizing the lifespan and maintenance of the lighting.
