Online Flashlight and Screen Light

Turn a computer, phone, or tablet display into a white, warm, cool, or colored screen light. It works as a night light, reading light, or temporary emergency light when no lamp is nearby.

Features

  • Pure white light and fullscreen mode
  • Adjustable color temperature from 2700K to 6500K
  • Warm white, cool white, amber, red, and custom colors
  • Brightness control and screen wake lock
  • Flashing SOS signal
  • 5, 15, and 30-minute presets or a custom 1–180 minute shutoff timer

How to Use

  1. Choose a preset color or adjust the color-temperature slider.
  2. Set a comfortable brightness.
  3. Enter fullscreen for a larger light surface.
  4. Enable wake lock or select an automatic shutoff timer for longer use.

Warm light is comfortable at night, while cool white light is useful for quick illumination. All controls run directly in the browser.

When the timer ends, the tool exits fullscreen, releases the wake lock, and shows a dark completion screen. One click restores the previous color and brightness.
