What light color temperature is recommended for reading areas?

For reading areas, a light color temperature in the range of 4000K to 5000K is recommended because this range provides a bright, neutral white light that is both stimulating and conducive to visual tasks. This temperature closely resembles natural daylight without being too harsh, making it easier to read and concentrate for extended periods. Light in this range helps reduce eye strain and enhances clarity, which is particularly important in settings where detailed work is being done, such as reading or studying.

In contrast, lower color temperatures, such as 3000K to 3500K, typically produce warmer, softer lighting that might be pleasant for relaxation but could lead to fatigue and decreased alertness during tasks that require focus. Higher color temperatures, like 6000K to 7000K, may evoke a stark, overly bright environment that might be uncomfortable for prolonged engagement in reading. Finally, very low temperatures, such as 2000K to 2500K, create a warm ambience akin to candlelight, which is not ideal for activities that need clarity and precision, like reading. Therefore, the 4000K to 5000K range offers an optimal balance for effective reading environments.
