Use this free white screen for light tool to turn your phone, tablet, laptop or monitor into a bright fullscreen lamp. Start with a pure white screen at full intensity, or choose cool white, daylight, warm white, soft amber, night red or a completely custom light color.
Adjust the simulated light intensity, set an automatic shut-off timer and keep the screen awake on supported browsers. The live preview updates immediately, while Fullscreen Light removes most browser controls to provide a larger illuminated area.
How to Use the White Screen Light
- Select Pure White for the brightest neutral screen or choose another light tone.
- Adjust the intensity slider and optionally select an auto-off timer.
- Choose whether the tool should request permission to keep the screen awake.
- Tap Start Fullscreen Light for the largest possible light area or use Window Light.
- Tap Turn Off Light, Stop Light or your browser's fullscreen exit control when finished.
Uses for a White Screen Flashlight
A bright white screen can provide soft nearby illumination for reading labels, finding objects, video calls, product photos, tracing, checking a display for dust or dead pixels, and creating simple background light. Warm white and amber tones may feel more comfortable in a dark room, while red light can help preserve some night adaptation.
The actual light output depends on the display size, panel technology and hardware brightness setting. The intensity control in this tool darkens the displayed color; it cannot raise the physical brightness beyond the level set by your device.
Fullscreen and Keep-Screen-Awake Support
Fullscreen and Screen Wake Lock are browser features, so availability may differ by device and embedded page settings. Fullscreen usually requires a direct button press. A wake lock can be released automatically by the operating system, low-power conditions or when the page becomes hidden; the tool attempts to request it again when the page becomes visible.
