Which lighting source is commonly used in classrooms because it does not glare on reflective surfaces and is more energy efficient?

Fluorescent light is commonly used in classrooms because it produces a soft, diffused illumination that reduces glare on reflective surfaces, making it easier for students to see and focus on materials without causing discomfort. This type of lighting is also more energy-efficient compared to traditional incandescent lighting, allowing for reduced electricity costs and a lower overall environmental impact. Fluorescent lights have a longer lifespan than incandescent bulbs, which contributes to less frequent replacements, thus minimizing maintenance efforts in a classroom setting.

While other light sources may also be utilized in various applications, they often do not provide the same balance of glare reduction and energy efficiency that fluorescent lighting offers, making it a popular choice for educational environments. Incandescent lights tend to generate more heat and are less efficient, halogen lights are generally brighter but may create more glare, and while LED lights are also energy-efficient and have a long life span, they can sometimes be harsher in their brightness compared to diffused fluorescent lights.
