Color temperature and CRI (Color Rendering Index) are crucial factors in LED (Light Emitting Diode) stadium lighting design, influencing visibility, atmosphere, and overall user experience. Here’s an exploration of their significance:

1. Color Temperature
2. Definition and Measurement

Kelvin Scale: Color temperature is measured in Kelvin (K) and defines the color appearance of the light emitted by the LED fixture.

Warm vs. Cool: Lower Kelvin temperatures (e.g., 2700K-3000K) produce warm white or yellowish light, resembling incandescent bulbs. Higher Kelvin temperatures (e.g., 5000K-6500K) produce cool white or bluish light, resembling daylight or overcast sky.

1. Application in Stadiums

Event Adaptability: Stadiums can adjust color temperature based on the type of event. For daytime events, cooler temperatures enhance visibility and mimic daylight conditions. Warmer temperatures may be preferred for evening events to create a more inviting atmosphere.
