White LED light color temperature guide

White LED light color temperature can be from 2000K to 10000K

Natural light is a dynamic source of white light, with changing tone and brightness, throughout the day and the seasons. The tone of white light is called color temperature and is expressed in degrees Kelvin (K).


The color temperature of daylight changes during the day, from 2000K at sunrise and sunset to 5500-6500K at noon. In the shade it can even go up to 8000-10000K.

Artificial light sources are available with all relevant color temperatures of sunlight. Some of them, such as incandescent lamps, can be manufactured with only one color temperature: 2700K. LEDs are light sources that can be produced with all color temperatures from 2000K to 10000K, with most common in the 2700-6500K range.

The choice of color temperature for the LED luminaires depends on where we want to use them and what atmosphere to create.

1. Warm white 2700K to 3900K

White 2700K luminaires have a cozy, intimate warm white light, which we recommend for use in living rooms and bedrooms. Warm white light is also considered good for relaxation. You may want to have warmer color temperature bedside lamps to prepare for sleep, as blue light can suppress the melatonin that the body naturally produces for falling asleep. For business applications, the warm glow creates a soft and personal, homely atmosphere in restaurants, hotels and retail stores.


White 3000K lights with a soothing warm white light are recommended for kitchens and bathrooms. Compared to 2700K, warm light at 3000K creates a relaxing atmosphere, but with a little more clarity in the surroundings, good for residential areas where you normally do tasks. For business applications, the warm glow creates a cozy, homely atmosphere in guest rooms, cafés and clothing stores.


White 3500K lights with a balanced warm white light that are best used for business applications that want to create a friendly, welcoming atmosphere that keeps people alert and focused at the same time. This desired effect fits perfectly in offices, clothing stores, hospitals, classrooms or dining areas.

2. Pure White 4000K to 4900K

White 4000K has a clean, focused, pure white light that can fit well in studies, garages and kitchens. Compared to the warm light that creates relaxation, pure white makes you focused and attentive. For business applications, this is ideal for offices, grocery stores, hospitals, classrooms and jewelry boutiques, especially those selling diamonds or silver.

White 4500K has a clean, focused, slightly cold white light that provides clarity in most tasks and creates a safe working environment. We recommend white 4500K light for classrooms, jewelry boutiques, especially for the sale of diamonds or silver, grocery stores or garages.

3. Cold white 5000K to 7000K

White 5000K lights with a vivid, cold white light that is suitable for high concentration and visual performance in most tasks and provides the safest working environment. We recommend white 5000K light for warehouses, hospitals, classrooms and car parks.

White 5700K is energetic light good for workplaces with specific tasks where an increase in concentration, performance and best contrast sensation is desired. Such places can be laboratories, factories and hospitals.

White 6500K lights are recommended for workplaces where tasks require increased concentration and performance. Such places can be laboratories, factories and hospitals. Another important application is agriculture, especially indoor horticulture.
