LightScreen

LightScreen is a free fullscreen light screen that runs in the browser. Open the site, pick a color, and any display becomes a flashlight, an ambient light, or a solid-color screen. There is no download and no sign-up.

Overview

Use Cases

Screen as a flashlight. In a dark room, a bright white screen is an instant flashlight. Set brightness from 0% to 100%.

Reading and night light. Warm or red light works as a gentler screen night light for reading and bedtime than a harsh phone flashlight.

Ambient and mood lighting. Scene colors and the breathing mode set a soft background for rest, focus, or a quiet room glow. Ambient Glow, Ambient Pink, Sleep Aid, Sleep Warm, and Baby Comfort are built for that.

Photo and video fill. White or warm fill light can stand in for a simple ring-light style source for portraits, product shots, or video calls.

Display checks. Full white, black, and primary colors help you look for dead pixels, backlight bleed, and color uniformity. A pure black screen is useful when checking OLED uniformity.

Stargazing. Red light is a practical choice when you want to read a chart without wiping out dark-adapted vision.
