Since the invention of the first light bulb by Edison in 1879, we have been enjoying the warm and cozy in every dark night rendered by the slightly yellowish color temperature by the 2700K incandescent bulbs for over 130 years. The color temperature is a method of describing the warmth (yellowish) or coolness (bluish) of a light source and measuring it in Degrees Kelvin (K) from 1,000 to 10,000.

The very soft yellowish lower color temperatures (2,700 – 3,000 K) are considered warm and produce a traditional warm and cozy feel. They are ideal for bedrooms, living rooms, or restaurant/commercial ambient lighting.
A bit whiter cool/bright white ones (3,100 – 4,500 K) are considered bright and vibrant. They are highly recommended for bathrooms, kitchens, garages, or work environments.
Comparing to sunlight (5,600 K), the blue-white color temperatures (4,600 – 6,500 K) mimics daylight and provide a crisp and invigorating feel. They are great for security/outdoor lighting, basements, or task lighting like reading, intricate projects, or applying makeup.
