Frequently Asked Questions

What is a screen fill light?
A screen fill light uses your device's display as a light source to illuminate your face or subject during photography or video calls, replacing or supplementing a physical ring light or softbox.
Is this tool free?
Yes, completely free. No sign-up, no subscription, no ads. Open the page and start using it immediately.
Will my screen stay on while using the fill light?
The tool requests Screen Wake Lock to keep the display on. If your browser supports it, the screen will not dim. If not, a notice will appear and you may need to adjust your device's auto-lock settings manually.
What is color temperature and which should I choose?
Color temperature describes how warm or cool a light appears. Lower values (2700–3500K) give a warm, golden glow ideal for portraits. Higher values (5500–6500K) produce neutral or cool daylight tones great for product shots or video calls.
Does it work on mobile?
Yes. The interface is fully optimized for mobile screens with touch-friendly controls. On mobile, the tool uses a fixed fullscreen overlay instead of the browser Fullscreen API for maximum compatibility.
