Which of the following is NOT a feature of energy-efficient lighting design?

The feature that is considered NOT characteristic of energy-efficient lighting design is higher initial costs. Energy-efficient lighting solutions, such as LED lights, typically have a higher upfront cost compared to traditional lighting options. However, this is offset by various benefits.

Energy-efficient lighting is designed to have a longer lifespan than conventional lighting fixtures, significantly reducing the need for replacements and maintenance. This longer lifespan contributes to lower operational costs since fewer replacements mean less spent on both the fixtures and the energy used in frequent replacements.

Additionally, these lighting solutions are engineered to consume less energy, leading to reduced electricity bills. The decrease in energy consumption is also connected to a reduced environmental impact, as lower energy use often results in fewer emissions and less strain on energy resources.

Overall, while the initial investment may be higher, the overall benefits such as lower operational costs, longer fixture lifespan, and positive environmental effects highlight the fundamental purpose of energy-efficient lighting design. Thus, the notion that higher initial costs are a feature of this approach is misleading, as the long-term savings and benefits far outweigh the initial expenditure.
