Edge Light for video calls

Product Introduction

1. Definition: Edge Light is a browser extension (technical category: real-time video enhancement software) that overlays a virtual ring light directly onto browser-based video feeds. It operates client-side without external hardware.
2. Core Value Proposition: It eliminates poor lighting during video calls by simulating professional ring light effects, ensuring users appear brighter and clearer without physical equipment. Primary keywords: virtual ring light, browser lighting extension, video call enhancement.

Main Features

1. Brightness Adjustment:

   • How it works: Users control luminosity via a slider that modifies the opacity of the light layer. The extension uses HTML5 Canvas and CSS filters to overlay light without distorting original video quality.
   • Technical specs: 10-tier granular control (0–100% intensity) with real-time rendering.

2. Color Customization:

   • How it works: Leverages RGB/HSL color models to apply skin-tone-optimized hues. The algorithm analyzes ambient light via the browser’s video feed to suggest complementary shades.
   • Technical specs: 22 Pro-tier color presets; HEX code input for custom tones.

3. Intensity Diffusion:

   • How it works: Adjusts light spread radius using Gaussian blur techniques, softening shadows around facial contours. Processes video frames at 30fps to maintain sync.
   • Technical specs: Radial gradient scaling (5–50px blur radius) to reduce harsh edges.

4. Cross-Platform Compatibility:

   • How it works: Built on WebExtensions API for seamless integration with Chromium (Chrome, Edge) and Gecko (Firefox) engines.
   • Technical specs: Supports macOS, Windows, Linux; requires no camera permissions.

Problems Solved

1. Pain Point: Addresses "cave effect" (dark, shadowy visuals) in low-light environments. Problem keywords: poor video lighting, unprofessional appearance, low-light video calls.
2. Target Audience:
   • Remote professionals (e.g., consultants, sales reps) needing polished visuals for client meetings.
   • Content creators and educators requiring studio-quality lighting for recordings.
   • Budget-conscious users avoiding hardware purchases.
3. Use Cases:
   • Critical presentations where facial clarity impacts credibility.
   • Backlit home offices with uneven natural light.
   • Night-time calls with inadequate room lighting.

Unique Advantages

1. Differentiation vs. Competitors:
   • Hardware Alternative: Unlike physical ring lights ($30–$100), Edge Light requires zero setup, storage, or power.
   • Software Alternative: Outperforms AI-based tools (e.g., Nvidia Broadcast) by being browser-native, resource-light (CPU usage <2%), and requiring no sign-ups.
2. Key Innovation:
   • Client-Side Processing: All rendering occurs locally; zero video data leaves the device (validated by Privacy Policy).
   • Dynamic Adaptation: Auto-scales light position relative to browser window size using viewport detection.

Frequently Asked Questions (FAQ)

1. Does Edge Light work with Zoom, Google Meet, and Microsoft Teams?
   Yes, it integrates with all browser-based video conferencing platforms (e.g., Zoom Web, Google Meet, Teams PWA) by overlaying light directly onto the tab.

2. Is Edge Light compatible with Brave or Safari browsers?
   Currently supports Chrome, Firefox, and Edge. Brave (Chromium-based) works unofficially; Safari is unsupported due to WebExtensions limitations.

3. How does Edge Light impact battery life during calls?
   Minimal impact—efficient rendering consumes <5% additional CPU. Tested on M1 MacBooks (3+ hours of continuous use showed <8% battery drain).

4. Can I use Edge Light Pro on multiple devices?
   The $14.99 one-time license covers lifetime use on all devices under one user account. Reactivate via "Restore License" after reinstalling.

5. Does Edge Light record or store my video data?
   No—processing occurs locally on your device. Zero video/audio data is transmitted to servers (confirmed in Privacy Policy).
