What is the purpose of installing barriers with luminaires?

The purpose of installing barriers with luminaires is primarily to minimize glare and protect individuals from live electrical parts. Barriers help diffuse the light emitted by the luminaire, which enhances visual comfort by reducing excessive brightness that can lead to discomfort or difficulty in seeing. Additionally, barriers provide a physical obstruction that prevents accidental contact with the electrical components of the luminaire, thus contributing to safety by reducing the risk of electrical shock. This protective feature is vital in ensuring that lighting installations comply with safety standards as outlined in the National Electrical Code, fostering a safer environment for users while ensuring effective lighting performance.
