adjust your display brightness based on the time of day LightBulb is a small application that can help reduce eye strain at night by automatically adjusting your display gamma levels based on current time of day. The program uses color temperature profiles to determine channel output levels for day and night and applies smooth transitions between them at sunrise and sunset. You can adjust the temperature values for daytime and nighttime based on your preference and also customize the transition duration and preview your settings with a simulated 24-hour preview. LightBulb automatically uses sunrise and sunset times based on your location but these settings can also be customized if needed. Copyright

Screen dimmed 5 stars by busybusy Dec 20, 2017 (Read all my 258 reviews)
LightBulb works well. It has a small memory footprint, works immediately after installation, and your done. Simple and efficient. After installation I did not know how bright my screen was which may have been causing me some eye strain, it dimmed it just enough to make looking at the screen comfortable. Wow, loving it! Kudos! Two-Thumbs Up! Get it, use it, Rate it! show Review details
