![]() Floodlights and motion-activated lighting need to be cool to provide unobscured illumination. Outdoor lighting for pure illumination should also be cool. Cool lighting also provides more clarity and detail, which is needed when preparing to go out for the day. For example, bathrooms and kitchens are great for cool lighting to reduce eye strain while preparing food or cleaning up. As well, warm path lights can provide unobtrusive walkway illumination.Ĭool lighting should be confined to areas of activity. Patio lights are often warm to keep a gentle glow without heavy light pollution. Warm outdoor lights should be used for mood and scene enhancement. ![]() You can also use warm lighting in outdoor areas. Consider the light from a candle or fireplace, which are both on the warm spectrum and conducive to relaxation. Warm light should be kept in areas of relaxation and calm, such as bedrooms, living rooms, and leisure reading areas. With those details in mind, you can use variable color temperatures throughout the home or office for maximum control. Cool lighting promotes energy and awareness.Warm lighting is inviting and enhances comfort.To best determine which temperature should go where, remember these details: However, it should work with such considerations to achieve the ideal lighting. Color temperature is independent of these other factors. Other factors, such as the size of the room or other specific light needs, can also be taken into account. With that in mind, it is important to use a range of color temperatures throughout your home or office. Likewise, a bedroom with cool lighting will interfere with sleeping, and reduce your ability to relax. Just as your mind reacts to different colors, the same is true with the color temperature of your lighting.Īn office illuminated with warm, yellow-spectrum light will decrease productivity. How to Maximize Color Temperature Throughout the Houseĭifferent temperature colors of lighting can affect your mood, productivity, and even your energy. The closer to blue, the higher the temperature, and the “cooler” the color. At this point, lightwaves are shorter and at the blue end of the spectrum. Warm lighting starts at around 1,900 K, and goes to approximately 6,000 K. The warm and cool refer to the color of the spectrum emitted by the light source. Warm light is lower on the Kelvin scale than cool light. It is important to note a unique distinction. ![]() Bedrooms and living rooms are thus ideal locations for warm lighting. Warm lighting is perfect for relaxation and comfort. This can include offices, study rooms, or kitchens during meal preparation. So, blue light, also known as cool light, is excellent for daytime illumination and areas where alertness is needed. For example, sunlight is high in blue light, which suppresses melatonin and helps keep you awake. With this knowledge, one can maximize the lighting of their home or office to provide the best benefits. Light temperatures begin much higher than Absolute 0. This is important in understanding the temperature of warm and cool light. There are no negative temperature measurements. This is the coldest possible temperature under (normal) universal circumstances. Unlike other scales, Kelvin begins at 0, also known as Absolute 0. These are based on the Kelvin scale of temperature measurement. When discussing the temperature and resulting color, we use a measurement called Kelvin (K). While these measurements are completely valid, they don’t tell us what we need to know about color temperature. And lumens are measurements of the light’s brightness. Watts are the measurement of the power through the bulb. Often, we think of lighting and light bulbs in terms of wattage or lumens.
