How to choose Kelvin temperature for LED lights

What Is Kelvin Color Temperature?

"The Kelvin (K) is a unit used to measure the color appearance of white light sources. It defines whether light appears warm (yellow/red tones) or cool (blue/white tones), helping users select the ideal hue for their needs.

How Does the Kelvin Scale Work?

Range: 1,000K–10,000K, representing the full spectrum of white light colors.

Key Principle: Lower Kelvin values = warmer light (more red/yellow); higher values = cooler light (more blue/white).

Example: A 2,000K bulb emits cozy, amber-toned light, while a 7,000K bulb produces bright, blue-tinged white light.

Why Kelvin Matters for Lighting

Mood & Functionality:

Warm light (2,000–3,000K) creates a relaxing atmosphere.

Cool light (5,000+K) enhances focus and alertness.

Color Accuracy:

Daylight white (4,000–5,000K) is ideal for spaces where true color representation matters (e.g., art galleries, makeup studios).

Energy Efficiency:

LED lights often offer adjustable Kelvin settings, allowing users to balance ambiance with energy use.

Visualizing Kelvin in Real Life

Sunrise/Sunset: ~2,000–3,000K (warm, golden hues).

Noon Sunlight: ~5,000–6,500K (bright, neutral white).

Overcast Sky: ~6,500–7,500K (cool, bluish white).
