Color Temperature for Bias Lighting
For pure eye strain reduction, use 6500K (daylight white). This matches the TV’s white point and provides neutral
backlighting.
For ambient mood, color sync systems create immersive experiences but aren’t as beneficial for eye strain.
Installation
- Clean back of TV
- Attach LED strip around edges (leave bottom open if needed)
- Connect power (USB or outlet)
- For sync systems: mount camera, install app
Tip: Place strips 2-3 inches from TV edge for best diffusion.
