    LightBulb info, screenshots & reviewsAlternatives to LightBulb
    LightBulb is an application that reduces eye strain produced by staring at a computer screen when working late hours. 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 - typically, sunlight during the day and artificial light during the night. LightBulb has minimal impact on performance and offers many customization options.

    At first, it didn't work, because of a Windows Update. (You can read about it here: https://github.com/Tyrrrz/LightBulb/issues/100)

    After deleting two registry keys, it works like a charm.
    Better than f.lux, imho.

    I switched from f.lux after using it for many years. Not that I had any problems with it, but I love LightBulb now

    Great! Let's you adjust Brightness and Temperature for Daylight and Nighttime. Works as expected.
