Color Temperature
- Warm White: Has a lower color temperature, typically between 2700K and 3500K. It’s similar to sunlight at dawn or dusk, candlelight, and the light from an incandescent bulb. The light has more red, yellow, and orange components, resulting in a yellowish or reddish appearance.
- Cool White: Has a higher color temperature, typically between 5000K and 6500K. It’s similar to sunlight at midday, with more blue components, resulting in a bluish or whitish appearance.
Visual Experience and Atmosphere
- Warm White: Warm, comfortable, relaxing, and inviting. It creates a soft, tranquil, romantic, and homely atmosphere, evoking images of fireplaces, candlelit dinners, and lounges.
- Cool White: Bright, clear, invigorating, and focused. It creates an atmosphere of efficiency, professionalism, cleanliness, and alertness, evoking images of hospitals, offices, laboratories, factories, and warehouses.
Applicable Scenarios
- Warm White: Ideal for areas requiring a sense of rest and warmth, such as bedrooms, dining rooms, cafes, and any environment where a warm hue is most important.
- Cool White: Ideal for areas requiring clear vision and focused attention, such as kitchens, bathrooms, offices, factories, hospitals, and more.
Other
