What LED Color Temperature to choose for a project, from 2700K to 6500K

Natural light is a dynamic white light source with changing tone and brightness, as a day goes by and seasons change. The tone of white light is called color temperature and is measured 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 in can even go to 8000-10000K.


Artificial light sources are available with all relevant color temperatures of sunlight. Some of them, such as incandescent lamps, can have only 2700K color temperature.

LEDs can have all color temperatures from 2000K to 10000K, while the most are found in the 2700-6500K range.

Our choice of color temperature for the LED lights we buy depends on where we want to use them, what atmosphere we want to create or behavior to empower.

Warm white 2700K to 3900K

White 2700K lights with a cozy, intimate warm white light that we recommend being used in living rooms and bedrooms. Warm white light is also considered good for relaxing. You may wish to have warmer color temperature bedside lamps to help prepare for sleep, as blue light can suppress melatonin that your body produces naturally at night to help sleep. For business applications, the warm glow creates a soft and personal, home like atmosphere in restaurants, hotels and retail stores.

White 3000K is a calming warm white light, recommended for kitchens and bathrooms. Compared with 2700K, light at 3000K creates a relaxing ambiance but with a bit more clarity in the environment, good for residential areas where typically you are completing tasks. For business applications, the warm glow creates a cozy, home like atmosphere in guest rooms, cafés and clothing stores.

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


Pure White 4000K to 4900K

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

White 4500K is slightly cool white light, focused and clean, that will bring clarity to most tasks and create a safe working environment. We recommend white 4500K light for classrooms, jewelry boutiques, grocery stores or garages.


Cold White 5000K to 7000K

White 5000K lights with a vibrant, cool white light, that is great for high concentration and visual performance for most tasks and creates the safest working environment. We recommend white 5000K light for warehouses, hospitals, classrooms and parking garages. 


White 5700K, an energetic - daylight white light, is good for workplaces with specific tasks. Especially where a boost in concentration, performance and best perception of contrast is desired. Such places could be laboratories, factories and hospitals.
