LightBulb is a desktop application that reduces eye strain by dynamically adjusting the screen's gamma and color temperature based on the time of day, transitioning smoothly between day and night settings using sunrise/sunset times. It is written in C# and runs as a lightweight tray application.
Use cases
- reduce eye strain at night by warming screen colors
- automatically dim screen brightness after sunset
- f.lux alternative for windows
- adjust screen gamma based on time of day
- schedule night mode color temperature shifts
- prevent blue light exposure in the evening
When to choose
- you want an open-source, lightweight f.lux/night-light alternative on Windows
- you need automatic sunrise/sunset-based color temperature transitions
- you prefer a tray app with minimal resource usage
When to avoid
- you need system-wide color control on Linux or macOS where native tools exist
- you need per-application color profiles rather than global gamma adjustment
- you require HDR display color management
