Why CRI Matters in Video Shooting

Strategic Summary
The power of a video light is not just measured in "lumens"; its true quality lies in how faithfully it reflects colors. At GDX, we explain why professional shoots require at least 95 CRI to protect your creative vision and save hundreds of editing hours.
1. What is CRI? Basics of Color Rendering Index
CRI (Color Rendering Index) is an international standard that measures how accurately a light source reveals the colors of objects compared to a natural source like sunlight.
💥 High CRI (95-100)
Colors are vivid and reflect true-to-life tones. GDX Lighting Systems are engineered to this standard, significantly reducing your color-correction workload.
✨ Low CRI (Below 80)
Colors appear "muddy" or desaturated. Specifically, gaps in the spectrum cause skin tones to look gray or exhibit unhealthy greenish tints.

2. Why is it Critically Important in Video Production?
- Natural Skin Tones: Low CRI makes actors look sickly. GDX ensures vibrant, cinematic, and healthy-looking skin tones.
- Post-Production Efficiency: Proper color accuracy reduces "fixing it in post" time by up to 50%. Focus on aesthetics, not technical repair.
- Product Authenticity: In commercial production, representing the exact product color is non-negotiable for brand trust.
Technical Detail & FAQ
Which is more important for video: CRI or TLCI? While CRI is for the human eye, TLCI (Television Lighting Consistency Index) is for camera sensors. GDX products provide 96+ scores in both, ensuring perfection for all digital captures.
How do I verify a light's CRI value? Trustworthy brands share full spectrometer reports. You can find spectrometer data for all GDX lights in the technical specifications section.
