1. About color temperature

Color tempreture

Color temperature is the color of light you see when you look at a light bulb. Color temperature is measured on a Kelvin (K) scale. Color temperatures of 3500K and above are generally considered cooler temperatures, with the hue becoming bluer (towards a clear midday sun) as the value increases. Temperatures of 3000K and below are considered warm. As the value is lowered, the light takes on a more amber tint.

For example, if you look at an LED light bulb, if its color temperature is 2700K, you will see a warmer yellow light, or if it is 5000K, you may notice a color similar to natural daylight.

In short, if you heat a sheet of metal to a temperature of up to 5,000 degrees, you will see a cool white. This is a way of saying that LED bulbs have a color temperature of 4000K or slightly higher.

These light temperature values (eg "4000K Led bulb") are based on correlated color temperature. In such calculations, the Kelvin temperature is critical, on a scale of up to 10,000K. Color temperature is usually an aesthetic choice; everyone usually has a different preference for every setting and application. 



Color Temperature

2. 3000K color temperature

3000K LED bulbs emit a warmer color temperature that is more yellow than white. While different temperatures produce different colors, the difference between 3000K and 4000K highlights that 3000K LED bulbs emit a yellowish and warmer light.

However, 3000K LED bulbs also integrate white, but at a slower rate. This warm yellow lighting is best for indoor objects that require a natural light finish.

For example, if your home contains earthy tones, choosing 3000K is the best choice. This color temperature is best suited for residential floor plans and interior living spaces. But most interior designers and decorators recommend avoiding warmer color temperatures in the kitchen, especially when it comes to white.


3. 4000K color temperature

In the 3000K vs 4000K color temperature debate, 4000K stands for cool white. If you have white home interiors, such as soft white cabinets in the kitchen, this could be the perfect solution for your lighting needs and requirements.

For example, the cool white hue of a 4000K bulb is great for accentuating any brightly colored objects around the house. This color temperature in LED bulbs is suitable for residential and commercial spaces.

What's more, it helps to reflect the white surfaces within the home, but not for wood-toned or earth-toned dwellings. Most of the time, people intend to use cool color transitions from warm yellow to warm white and then to cool white light, mostly on white surfaces.


4. 5000k color temperature

5000K is brighter than 3000K, 4000K warm light. This is because the 5000K color temperature is on the high end of the color spectrum. What's more, homes choose these lights during highly focused and discreet tasks like construction or maintenance to ensure personnel or residents can work with maximum clarity.

You have to keep in mind that with 5000K LED lights there is a greater chance of eye strain due to the high intensity lighting. It's closer to broad daylight, which is why it's suitable for parking lots, large outdoor venues, and industrial lighting installations. In fact, the blue light from 5000K LEDs looks cooler than the room itself.


5. What is the difference between 3000K, 4000K, 5000K?

6. Why is color temperature important?

Color temperature is especially important in the lighting industry, where differences in color temperature can affect how colors are rendered and, ultimately, the mood and mood of a room or environment.Here are the reasons that why you should choose a suitable color tempreture:

A. Choosing the right color temperature allows you to avoid complications that could irritate your eyes.

B. The right color temperature allows you to buy the right item you need without incurring recurring charges for unnecessary power consumption.

C. Having the right color temperature can help you invite more customers because they will be attracted to a specific color temperature.

Color temperature is usually an aesthetic choice, depending on location and application. Suntech LED are available in a variety of color temperatures - cool bright white to warm yellow. Below is a list of the most popular color temperatures for LED lighting and their typical applications.We prepared  a table for you to introduce it better:


Table2- application for different color tempreture-Suntechled

Color

Application

Very warm white (2200K)

This is the lowest color temperature possible for white light (any lower is yellow!) Also known as candlelight, it is used in very romantic, low-key settings, such as around outdoor fireplaces and hot tubs. It is also similar to High Pressure Sodium (HPS) commonly used in street lights and is less common in 120v moonlight lighting.

Warm White (2700K)

Similar to halogen landscape lighting, it is the most preferred color temperature for landscape lighting. Psychologically, it is considered more welcoming and soothing than higher color temperatures.

Warm white or natural white (3000K)

Significantly lower than 2700K, which some landscape lighting experts prefer. It tends to accentuate greens and blues in vegetation.

Cool White (4000K)

Quite bluish compared to 2700K, which is sometimes used to illuminate blue vegetation (such as blue spruce). It is also used to simulate moonlight (4200K).


7. The best color temperature for different types of outdoor lighting

A. Residential lighting

The main Kelvin range used in residential outdoor lighting is between 2500k-4000k. According to experience, building elements use a warmer color temperature (between 2500k-2700k), which will have a harmonious, bright, clean, and tall feeling. Against the background of the surrounding green plants, the coordination is not only appropriate, but also very eye-catching.

B. Landscape lighting

When lighting an outdoor landscape, stay away from cooler color temperatures. Blue hues from cooler temperatures can make the environment look sick or unnatural, giving a feeling of restlessness and tension. Instead, choose lighting with a very warm color temperature: 2700K LEDs are ideal, and 3000K is fine too. The 2700K temperature provides a very soothing and natural tone that mimics the warm, cozy glow of a campfire. Therefore, it is ideal for creating a relaxing and comfortable outdoor environment.

C. Outdoor living and entertainment areas

You want your entertainment area to create a feeling of calm and relaxation so your guests can enjoy the space to the fullest. Warm light, such as 2000K-3000K, tends to be best for these purposes. They're not too harsh on the eyes, but still provide enough light for everyone to move around safely and see what's around them. If you're wondering what this would look like, imagine sitting by the stove. That warm glow is exactly what you'll get from warm temperature light.

D. Garden lighting

If you want to show off any beautiful plants you've spent countless hours caring for, you'll want white LED garden lighting in the 3000K-4000K range. This neutral white provides more natural garden light and accentuates the gorgeous natural bright colors of your garden.


8. How do I choose between 3000K, 4000K, 5000K ?

3000k,4000k,5000k

3000K: This temperature range produces a nice and comfortable warm white light. It helps create a calm and intimate atmosphere and is ideal for outdoor living rooms, outdoor kitchens and decorative outdoor lighting.

4000K: This temperature range produces gorgeous cool white light. This temperature range is bright and vibrant, helping to dissipate shadows and give people a clear view of their surroundings. It's the perfect lighting for areas around stairs, sheds or outdoor workshops, as the color keeps the light focused and encourages people to stay alert and focused.

5000K: This temperature range mimics natural sunlight/moonlight. It's crisp and clear, helping to draw attention to detail and draw attention to the central focal point. That's why this temperature range is used for security lighting, lighting areas around garages, or to help showcase gorgeous water features like fountains or ponds.

9. When to use warm light and when to use cold light for facade lighting?

When to use warm light:

For residential outdoor lighting, the main Kelvin range you use is between 2500k-4000k. A useful rule of thumb: use a warmer color temperature around 2500k-2700k on architectural elements, and save a cooler color temperature between 3000k-4000k for trees and plants.

When to use cold light:

But if you want to show off the natural beauty of plants and foliage, neutral white light usually works best. You want to choose a higher Kelvin range around 3000-4000k. Many plants appear more natural with higher Kelvin light sources, especially white outdoor lighting makes plants appear more natural at night. When lighting your garden from high down, why not try structures like trees or trellis? You'll want to stick to a Kelvin level of 4000k, as this will mimic the color of natural moonlight (this technique is often referred to as "moonlight").


10. 4000K and 5000K, which one is more similar to natural daylight?


Comparing LED bulbs to natural daylight is a bit tricky, because natural daylight itself is always changing, depending on the weather, time of day, season, and latitude. The reason is that the sun itself has a constant color temperature of about 5800K, but depending on the color of the sky, the color temperature of natural daylight can vary significantly.

In general, the redder/orange the sky (morning or afternoon light), the lower the color temperature, and the bluer the sky (noon daylight, or windows facing away from the sun), the higher the color temperature.

Therefore, you will find that the color appearance of a 4000K LED bulb is similar to that of natural sunlight in the morning or afternoon, at noon, the color temperature of direct sunlight will exceed 5000K.

4000K - Early morning 5000K - Noon


Finally, just because an LED bulb emits a color that looks like natural daylight doesn't mean it has the same spectrum as natural daylight. If you're looking for LED lights to perform color-critical tasks, or looking for full-spectrum lighting for health-related applications, you'll want to look at the Color Rendering Index (CRI) values of your LED bulbs for a better sense of spectral similarity. A high CRI value of 95 or higher generally ensures that the spectrum does indeed replicate the natural spectrum.

FAQ:

1. Is the 3000K LED light cold or warm?

Although the 3000K color temperature is to the left of the white scale of Kelvin temperature, it is a warm light.


2. What is the difference between warm white and yellow light?

2200K is the lowest color temperature possible for white light, anything lower is yellow light.


3. Will 4000K appear too white?

Let's say you're considering a 4000K for your home kitchen area. At night, if you walk from a 3000K living room light into a 4000K kitchen, it will definitely look whiter, will it look too blue? We don't think so - it's definitely a stronger white, but not a harsh blue.


4. Is 4000K Too Bright?

Brightness depends on lumens, not color temperature, and 4000K is a great temperature that has a perfect mix of color that is not too yellow and not too blue. 


5. Is 5000K suitable for outdoor lighting?

For residential outdoor lighting, use a warmer color temperature around 2500k-2700k on architectural elements.


6.What is a good LED light for facade lighting?
