One of the best things about LED technology is that it allows you to create your own custom lighting design using color temperature, brightness, warmth and efficiency. By considering the Kelvin temperature, you can ensure that the light fixture complements the intended purpose and ambiance of the space. Different colors of light can impact our mood and behavior. But how does one actually choose the color temperature of their LED lighting? For those unfamiliar, we’ll explain the importance of CCT, how to choose based on your application, and how field-adjustable CCT products help make choosing even easier.
CCT Meaning and Kelvin
As you’re shopping for LED lighting, you’ll notice that some LED products, like LED bulbs, offer a choice of color temperature in various hues of white. That temperature, a measure of the “color” of a light source, is defined as correlated color temperature (CCT). CCT is expressed in degrees of Kelvin (K) and measured on a scale of 1,000 to 10,000 K. Lower Kelvin values indicate warmer light, while higher Kelvin values indicate cooler and blueish light. It’s important to consider the color temperature when choosing your fixture, so that the look and feel of the light matches the mood and atmosphere you’re trying to set.
As a general rule of thumb, the higher the degrees of Kelvin, the closer the light’s color output will be to actual sunlight. A warmer white is usually 3000K or less, while a neutral white commonly has a temperature of 4000K. At 5000K and higher on the Kelvin scale, the result is a “cool” white light. Typically, Kelvin temperatures for commercial and residential lighting applications fall somewhere between 2500K and 5000K.
In addition to considering the type of light bulb, utilizing Kelvin temperature can assist in selecting the appropriate fixture for different settings. Whether you require light for ambient lighting or focused tasks, the following Kelvin ranges can serve as a helpful guide:
Warm and Cozy Ambience (2200K-2700K): These Kelvin ranges can create a comfortable atmosphere in living spaces, bedrooms, and dining areas.
Neutral White (3000K-3500K): Falling within this range, this Kelvin temperature provides a well-balanced and adaptable lighting solution which is preferred for general lighting purposes in offices, kitchens, and retail environments.
Cool White (4000K-4500K): With a higher Kelvin range, this light temperature promotes focus and concentration making it suitable for task-oriented areas such as workstations, garages, and workshops.
Daylight and Outdoor Lighting (5000K-6500K): This Kelvin range effectively emulates daylight and is widely employed for outdoor lighting or areas demanding maximum brightness and clarity. It is especially suitable for illuminating stadiums, parking lots, and outdoor recreational spaces.
Application Examples
Living Room – A warm white light 2200K-3000K is best for the living room since it creates a cozy, inviting atmosphere that helps you relax and unwind.
Bedroom – Warm white light with a color temperature between 2200K-3000K is ideal since a relaxing and comfortable environment is needed for a bedroom.
Bathroom – A color temperature of 3000K-4000K will help create an atmosphere that makes us feel relaxed and rejuvenated, but with enough light to concentrate on tasks like shaving and applying makeup.
Kitchen – The kitchen is where people want to feel energized and inspired because it’s considered the gathering spot in the home. Adequate task lighting is also needed for food prep and reading recipes. A color temperature of 3000K-3500K will help achieve this goal.
Office – An office is where people need concentration and focus. In this environment, a color temperature that is not too stimulating is quite important, as this can lead to distraction and decreased productivity. A cool white or daylight temperature (3000K-4000K) is best for an office setting.
New CCT Technology
In recent years, more and more LED lighting brands are releasing products that feature revolutionary CCT technology: a CCT switch offering color temperatures in a range. This highly requested feature allows you to create the perfect ambiance for your application and enhance your overall lighting experience.
CCT technology offers unmatched versatility and convenience for your lighting needs. With three, or often five color temperature controls, you can effortlessly transition between various color temperatures spanning from a warm and cozy ambiance (e.g. 2700K) to a cool and crisp atmosphere (e.g. 5000K), all within a single fixture. LED products with selectable CCT include LED recessed downlights, under cabinet linear fixtures and puck lights, strip lights, outdoor wall lights, flood lights, commercial fixtures such as wall packs and flat panels, and more.
