The warmth or coolness of light is called the color temperature. This has nothing to do with the actual heat of the bulb, only the appearance of the light. In addition to using terms such as "warm white", "cool white" and "daylight" to describe these color temperatures, we also rate them in Kelvin, a temperature scale.

Therefore, to understand Warm White, Cool White, Daylight, you must first understand the Kelvin color temperature. The higher the Kelvin (or K) value of the bulb, the whiter the light.


1. What is color temperature?

Color temperature is a description of the warmth or coolness of a light source. When a piece of metal is heated, the color of the light it emits changes. The color starts as a red in appearance and progresses to orange, yellow, white, and then bluish-white to a deeper blue. The temperature of this metal is a physical measure in degrees Kelvin or absolute temperature. While lamps other than incandescent lamps such as LEDs cannot fully mimic the output of this piece of metal, we use correlated color temperature (or Kelvin) to describe the appearance of this light source as it relates to the appearance of the metal piece (specifically a black body heat sink).

By convention, yellow-red (like fire) is considered warm, and blue-green (like light from an overcast day) is considered cool. But on the contrary, we consider higher Kelvin temperatures to be cool colors and lower color temperatures to be warm colors.

Bulbs with a Kelvin value less than 2000K will glow yellow.

2000K to 4500K bulbs go from a soft yellow-white light to a bright white light.

Bulbs from 4600K to 6500K emit blue-white light, and bulbs over 6500K emit blue light.

It is important to note that there is no absolute consensus on what Kelvin scale is equivalent to what color temperature description. Visit different sites and you'll get different answers, but here's a general guide we've put together for you to refer to.


2. Warm white

Warm white lighting is one of the most popular lighting in the home and also the best option for outdoor architectural lighting. Warm white light has an orange-yellow tint, similar to old-fashioned incandescent or halogen bulbs. In indoor locations, the best place to use warm white light bulbs is anywhere in your home where you spend a lot of time relaxing and relaxing, such as bedrooms, living rooms, dining rooms, etc. where you perform fewer tasks, require less lighting, and don’t require concentration . In outdoor lighting, warm white is generally used for exterior wall lighting, and is often used as summer light in gardens.


3. Cool white

While there is a full spectrum, whites can often be divided into warm and cool whites. Cool white LEDs tend to give you a cleaner look and are perfect for modern kitchens, where appearance and optimal light really matter, such as sewing rooms and garages. Because white lights are brighter and warmer lights, they are typically used in the busier parts of the home where you tend to cook or work. Used outdoors to illuminate blue vegetation, cool white temperatures are often used to simulate moonlight, commercial, retail, and art studios.


4. Daylight

On the far end of the spectrum are fluorescent lamps. They make ideal Christmas lights and decorations because they resemble ice and frost. These lights can border on blue light. At home, many people find these a little too "clinical" and prefer to use warm LEDs or cool LEDs. Because the light replicates natural daylight, but with a little bit of shine, that's why they're perfect for Christmas. Like cool white, daylight is also perfect for task lighting, with a bluish tinge. This light shade will maximize color contrast and produce vibrant and intense lighting, which is often ideal for work, reading, security lighting, or applying makeup.

6.Which one is better for outdoor lighting?

outdoor lighting projeectOutdoor spaces are often overlooked when darkness devours the sun. The best way to eliminate shadows is to set the mood of your outdoor space by setting artificial lighting to make the outdoor space atmosphere dreamy and scenic at night, which color is better for your outdoor landscape lighting, warm white or cool white?

The lighting you choose for your landscaping depends on what you plan to emphasize with your lights. Using lights between 2500K and 2700K(warm white) is a good range for accentuating architectural features, while illuminating plants works best at 3000K to 4000K(cool white). Different types of lighting work best for different parts of your landscaping, depending on how you want people to feel when viewing your home or business.

Pro tip: Cooler color temperature lighting can make your yard look unnatural, so stick to warm and natural whites to properly showcase your landscape.

7.Which one is best for indoor lighting?

For indoor venues, different rooms and spaces are suitable for different shades. Here are some general suggestions:

Indoor lighting

Warm light in the bedroom. Warm lights make more sense in bedrooms, especially with night lights, as lower levels of blue light won't have much of an effect on your sleep patterns.

Cool light for the office. Now that the home office has become a necessity for work and school, cool lighting is great here to promote focus, alertness, and clear video conferencing!

Cold light in the kitchen. Many homeowners find that cool white lighting works best in the kitchen because it provides a clean and modern feel and provides full lighting for cutting and cooking.

Warm or cool light in the bathroom. Warm lighting may also be better for bathrooms, as this can provide a relaxing feel to a warm shower or hot tub. If you already have a lot of white in your bathroom (like the tub, sink, or tile), it can be shocking to see a burst of bright white light first thing in the middle of the night or in the morning! Although just like in the kitchen, cool light in the bathroom can enhance cleanliness and provide a comfortable environment for self-care tasks that require full visibility, such as shaving or applying makeup. The variety of lighting options for this room—and plenty of atmosphere-enhancing candles—may help create the ideal lighting for many situations.

Warm light in the dining room. Warm lighting in the dining area can bring comfort to your family meal or dinner party.


8. How do I choose between warm white, cool white and daylight?

In fact, in the final analysis, different environments, locations and functions need to use different color temperatures, but the color temperature also depends on people's preferences, there is no fixed option, some people think that bright white light gives people a lively feeling, Or some may want to create a more relaxed environment, which means less light.

We recommend warm white(2000-3000K) for Living room, dining room, bedroom or any other room that needs soft lighting. Warm whites are more relaxing to the eyes, soften the complexion and reduce blemishes. We all look better in warm white.

We recommend cool white(3000-4500K) for: Kitchens, garages, workshops, product displays, hair salons, powder rooms, industrial applications or any other application that requires lighting that represents the true color of objects. Also, cool whites are always brighter than warm whites.

We recommend using the daylight(4500-6000K) for Garages,workshops Floodlights,Security lights. If you feel that cool white is too blue for your taste and warm white is too yellow, then you can try natural(cool) white lighting. 


9. Some advides for when to use warm light, cold light and daylight.

When lighting indoor entertainment areas:

Consider lamps at the lower end of the Kelvin scale, around 2000K, that provide a warm reddish light that can mimic flame light. This is the same light you get from candles, tiki torches, or a blazing campfire. Strategically placed, lights in this range are where you need a romantic or rustic feel.

When lighting outdoors and landscapes:

Please choose a soft and relaxing soft warm white light (2700K) for use with wall washers on the facade of your home, warm white is the most preferred color temperature for landscape lighting. Warm white light (<2700K) is also used to accentuate greens and blues in vegetation.

Cool white (4000K) is sometimes used to illuminate blue vegetation (such as blue spruce).

When you are lighting street roads:

Consider 4000K artificial moonlights, which are placed high on a tree and aimed down to provide a broad light that illuminates the area below. These lighting fixtures are equipped with special glare shields that wrap around the bulb to ensure the light is directed downwards.


10.Conclusion:

At the end of the day, color temperature is a personal preference and there is no absolute right or wrong choice. Some people will like to use bright white light to give a lively feel, or some people may want to create a more relaxed environment, which means less light. Which one to choose depends on which ambience you prefer and the characteristics of the space you are using.
