The warm white varies from 3,500 K to 4,000 K, and has a yellowish hue. It is ideal for residential use – bedrooms, lounges – where they recreate relaxing environments.

It is known as the most yellowish tint of light. It is reputed to be associated with incandescent light bulbs. The warm white provides more relaxation, this because it produces less lumens than cold white.

Such tone is suitable for bedrooms, dining rooms and living rooms, as well as for dressing rooms, since warm white keeps the colors more natural. The color of the food, as well as the skin, appears closer to the natural under that hue.


The cold white varies from 6,000 K to 6,500 K, and is the brightest type of light and has a bluish tint. Cold light is often used in workplaces such as offices and warehouses where vivid colors such as white, blue or violet predominate. It is also commonly used in bathroom, kitchens and corridors.

Warm white is ideal when you want to create cozy atmosphere. Cold white is used, especially in places where there is a lot of activities and in especially dark areas.
