LightBulb is a free and open source Windows app that automatically adjusts the screen color temperature based on your geographic location (sunrise & sunset times) and manually set times to reduce eye strain while staring at a screen. #Windows #Tools

As the day goes on, it continuously adjusts gamma, transitioning the display color temperature from cold blue in the afternoon to warm yellow during the night.

Its primary objective is to match the color of the screen to the light sources of your surrounding environment — sunlight during the day and artificial light during the night.

LightBulb has minimal impact on performance and offers many customization options, as shown in the attached images.

Current support for Windows 7 and higher, better than win10 and win11 built-in color temperature adjustment function.
