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).
