LightBulb Official Version is an easy-to-use software tool specifically designed for eye protection during computer use. It can be installed and operated directly on your PC, helping to significantly reduce eye strain and fatigue caused by prolonged screen exposure. The primary goal of LightBulb is to adjust the screen's color temperature so that it harmonizes with the ambient lighting in your environment, providing a more natural and comfortable viewing experience.
LightBulb Software Introduction
LightBulb is a screen color temperature adjustment tool and blue light filter that reduces blue light emission to help protect your eyes. It serves a similar purpose to the well-known software f.lux, but with the added benefit of being open-source. LightBulb automatically adjusts your screen’s color based on sunrise and sunset times—shifting to warmer, more amber tones in the evening. This reduces eye strain and supports better sleep hygiene, making it ideal for users who spend long hours in front of their screens.
LightBulb Software Advantages
1. Smooth Temperature Transition – Gradually adjusts screen color temperature over time, avoiding abrupt changes that can be distracting.
2. Automatic Pause in Full-Screen Mode – Temporarily disables color adjustments when a full-screen application or game is active, ensuring optimal visual quality during gaming or video playback.
3. Configurable Global Hotkeys – Allows users to set custom keyboard shortcuts to quickly enable, disable, or toggle the software.
4. Low System Impact – Runs efficiently in the background with minimal effect on CPU and memory usage.
5. Extensive Customization Options – Offers detailed settings for color temperature, transition duration, brightness limits, and activation times to suit individual preferences.
6. Flexible Scheduling – Supports both automatic (online) detection of sunrise and sunset times based on your location, as well as manual configuration for full control.
LightBulb Usage Instructions
1. After downloading and extracting the files, double-click Manual_Gamma_Registry_Fix.reg to import it into the Windows registry. Then restart your computer. (Skip this step if you've already applied the fix.)
2. Run the portable version of the software by launching LightBulb_Portable.bat—do not run LightBulb.exe directly. This ensures settings are saved correctly in portable mode.
3. All configuration settings are saved automatically in the Configuration.dat file, making it easy to back up or transfer your preferences.
