Overlighting refers to the provision of excessive light in an area, which can lead to several issues, with higher costs being a significant disadvantage. First, when too much lighting is used, it results in increased energy consumption, leading to higher electricity bills. Additionally, maintaining and operating more lighting fixtures than necessary often incurs higher upfront and maintenance costs.

Furthermore, overlighting can strain the electrical system, potentially leading to more frequent repairs or upgrades. This condition can also diminish the lifespan of light bulbs and fixtures because they are running longer than needed, thus increasing replacement costs over time.

In contrast, options like increased energy efficiency, enhanced ambiance, and improved safety may be associated with appropriate levels of lighting. However, when overlighting occurs, it typically does not promote these benefits and, instead, contributes to financial inefficiencies.
