What Are Light Temperatures?
Light temperature refers to the color tone of light emitted by a bulb, measured in Kelvin (K). Different light temperatures create different atmospheres and serve various functions:
Warm Light (3000K-3500K) – A soft, golden glow similar to candlelight or traditional incandescent bulbs. Ideal for cozy, relaxing spaces such as bedrooms, living rooms, and dining areas.
Neutral Light (4000K-4500K) (Also Termed "Daylight") – A balanced, natural white light that mimics daylight. Perfect for general home lighting, kitchens, offices, and workspaces where clear visibility is needed without being too harsh.
Cold Light (6000K-6500K) – A crisp, bluish-white light that enhances focus and visibility. Commonly used in task lighting, bathrooms, and areas where a bright, invigorating atmosphere is desired.
If a lamp is listed as "changeable," "trichromatic," or "three-colored", it means you can switch between warm, neutral, and cold light settings in one lamp, offering versatile lighting for different moods and needs.
