Understanding the color of LED lights, which is known as Kelvin temperature (K), can make it easier for you to choose the right types of lights that will give you the perfect effect that you want.
Warm white: 2700K ~ 3000K, produces calm, relaxing light that is good for any room–bed rooms, living rooms, dining rooms or in restaurants.
Natural white: 4000K ~ 4500K, produces a friendly, inviting light that is suitable for any room. It is also ideal for offices, basements, garages and other work environments.
Cool white: 5500K ~ 6500K, produces vibrant light, which is recommended for display areas, security lighting and garages.
Buyers of LED lights should ask about the correlated color temperature of a lamp or fixture before purchasing it. Another important thing to note?not all 2700K CCT lamps will look the same. So to avoid any issues, it is best not to mix and match manufacturers unless you have tested their products with each other.
How to select the right color for your application?
Warm colors can be perceived as ?not bright enough? if they are used in an area where people want crisp white light to work under.
In areas where naturally cool-colored daylight enters from windows and skylights, warm colors tend to look more yellow or pink. People think that the lights are not working properly.
The potential downside of using cool colors is that many people perceive it to be ?institutional? or ?sterile?. People may complain that their lighting is ?too bright? if you change from a warm color to a cool color, even if the measured light output remains the same or decreases slightly.
Evaluating the needs of your environment is key to picking the right color temperature. Make sure you tell your supplier what type of environment or what type of ambience you are looking to create in a space.
Also, if you plan to shift from one light source to another (fluorescent to LED), or changing the CCT, it is recommended to finish the entire rooms at the same time.
