Study/Work-from-Home Lighting | Lighting and Color Temperature for Enhanced Concentration

Working from home or in a study is a time when you want to focus. In such cases, the lighting environment can affect how easy it is to work.

While "concentration" depends on your physical condition and the nature of your work, in terms of light, you can adjust the brightness and color temperature to promote concentration.

Brightness and Color Temperature Suitable for Work

According to the JIS illuminance standard (JIS Z 9110), approximately 500 lux is a guideline for desk work. A crisp white color temperature (around 4000K) is considered suitable for work scenes, as it is neither too bright nor too subdued.

Lighting That Is Gentle on the Eyes During Screen Work

• Reduce the contrast between the screen and its surroundings: Looking at a bright screen in a dark room creates strong contrast, which can strain the eyes. Keep the entire room moderately bright.
• Consider glare and flicker: Uniformly diffused light, flicker-free design.
• Brighten your face: During web conferences, having enough brightness to illuminate your face is also important.

For lighting tips on how your face appears in web conferences, please refer to Web Conference Facial Lighting.

It's Convenient to Switch Throughout the Day

A crisp white light for when you want to focus, and a warm incandescent color for breaks or after work. With a dimmable and color-tunable ceiling light, you can switch between work and relaxation with a single unit. For an explanation of color temperature, please see What is Color Temperature?.
