Which light is commonly used for reading?

The most suitable choice for reading light is LED. LED lights are popular for reading due to their energy efficiency, long lifespan, and the ability to produce a bright, clear light that closely resembles natural daylight. This type of light helps reduce eye strain, making it easier to read for extended periods.

Additionally, LEDs come in various color temperatures, allowing users to select a light that is most comfortable for their reading environment, whether they prefer warm or cool light. The directional nature of LED lighting also makes it easier to direct light specifically where it's needed, maximizing illumination on a book or page.

While other options like CFL, incandescent, and halogen lights can also be used for reading, LEDs generally provide better efficiency, longevity, and light quality that is preferred for this activity.
