LightBulb will continuously change the screen gamma using temperature profiles, making the colors appear warmer at night or any way you like it.

LightBulb is easy to setup, and test various colors, temperatures, and duration. The arrow button is a 24-hour preview that shows how it will appear over 24 hours in around 15 seconds. It quietly resides in your systray for quick access and deployment.



Once opened, it quickly picked up our location immediately but does include options for geolocation. You have the option to disable internet synchronization, but if you do, you will need to set your sunrise and sunset times manually.

There are a number of advanced settings that include gamma polling, temperature smoothing, pause when full screen as well as the option to toggle LightBulb and gamma polling with most keys, not including letters.

There are quite a few of these screen gamma utilities on the market, but LighBulb's numerous settings along with the 24-hour preview really let you know what to expect.
