White Screen for Lighting
This white screen for lighting turns your display into a soft, adjustable light source for video calls, a backup flashlight, or bright, even lighting for tracing and craft work. Brightness and color temperature are both adjustable, and the Zoom Light preset sets both in one tap.
Common uses
Video calls
Place a second device off-screen showing this page to fill in shadows on your face during Zoom, Teams, or Meet calls.
Flashlight
Set brightness to 100% and white for a bright backup light in a dark room.
Tracing & craft work
A tablet or laptop screen under paper works as a simple light box for tracing sketches.
Reading light
A warm, dimmed screen makes a gentle reading light when the room is dark.
Match your room
Warm bulbs (incandescent) pair best with a warm setting on the slider; cool LEDs or fluorescents pair best with a cooler one. When in doubt, start near the middle. Place the screen at eye level, about 40–80cm from your face, for the most natural fill light.
Frequently asked questions
What color temperature should I use for video calls?
Can I use my phone screen as a flashlight?
Will this drain my battery quickly?
The light here comes straight from your screen's own backlight at the brightness you set, not a simulated glow layered on top. Because real output depends on your device's panel, the guidance sticks to adjustable settings rather than a fixed lumen claim, and is checked against how phones and laptops are commonly used as fill lights.
