Difference Between 3000k And 4000k Color Temperature Lighting

The difference between 3000k and 4000k color temperature lighting is a headache for many people.

Are you wondering about this question? The color temperature range is extended, causing a massive difference in experience. This fact requires consumers to understand their properties to find the most suitable LED bulbs.

In this article, let’s dive into the color temperature lighting, especially understanding the apparent differences in 3000K vs 4000K.

Color Lighting Temperature Brief

Color temperature overview
Color temperature overview

Color lighting temperature is a term to describe the colors you can see when looking at a specific type of light.

With today’s commercial LED bulbs, the unit of measurement for temperature lighting is Kelvin, abbreviated as K. Lighting devices have color temperatures range ranging from 1000k to 10000K.

Color temperature is one of the most critical parameters of a lighting device. We can see that each different color temperature gives light its distinct properties. There are some standard color temperatures that you should be aware of:

  • 2700K: Warmer white lights
  • 3000K: Soft yellow white lights
  • 3500K: Neutral white lights
  • 4000K: Cool white lights
  • 5000k: Bright white lights
  • 6500k: Natural sunlight during the day

The higher the color temperature, the whiter the light will be. This color gives a energetic and concentrated feeling. Conversely, bulbs with low color temperature will produce yellow and red lights. These lighting devices will put user in a soothing mood.

In particular, LED bulbs commonly used in households will have color temperature of 3000K and 4000K.

So in this article, we will dig deeper into the differences between these two types of color temperature. You need to understand the effect of each one to make the smartest choice.

3000k light

The following sections will help you better understand 3000K lighting.

Is 3000k warm or cool color temperature

At 3000K color temperature, the light produced is cool yellow one.

The color of 3000K lights is not too yellow, but it also feels soft and some kind of ambient. 3000k does not have the blue beams that LED with higher color temperatures can produce.

If you love Traditional Incandescent vibe, you will be satisfied with the 3000K LED. The light produced by these two has nearly similar properties. They are all white but have a yellowish tint, making you think of transparent amber.

However, LED lights limit heat generation, save energy and have a longer life. Therefore, many consumers prefer LED over halogen or incandescent lamps.

Is 4000k too bright or not?

The light has a color temperature of 4000K which is not too bright.

4000K LED will give you light with neutral colors which is not too dark nor too bright, suitable for many different uses.

It’s also important to remember that brightness is frequently expressed in lumens rather than color temperatures. A more excellent lumen rating denotes brighter light, while a lower value denotes dimmer color.

Indeed, 4000k color temperature lighting is considered pretty bright and may be appropriate for situations that need a lot of light, including big rooms or outdoor environments. It could be excessively optimistic for smaller spaces or places with softer, more ambient lighting is preferred.

Brief Difference On 3000k vs 4000k vs 5000k

As we mentioned above, different color temperatures produce light with distinct properties. The following section will discuss the difference between 3000k vs 4000k vs 5000k.

This difference manifests in four main aspects. These criteria include the Kelvin scale, appearance, blue light, and the color rendering index.

Kelvin Scale

Correlated color temperature (CCT) in Kelvins
Correlated color temperature (CCT) in Kelvins

The first and most noticeable difference in these types of lights is their color temperatures parameter on the Kelvin scale. The Kelvin degree in sunlight is the standard unit for determining the color temperature of a light source.

The light will be yellow, red and warmer at low Kelvin color temperature thresholds. Contrary to that, the emitted lighting source will have an excellent white color at higher color temperatures.

Accordingly, 3000k lights give off a warm white color. When standing next to a 4K source, you will see that the light emitted from the 3000K LED has an additional yellow tint. Meanwhile, the 4000K LED provides a neutral cool white color. In contrast to the 3000K LEDs, the 5000K LED has an excellent white one thanks to the addition of a blue tint.


Because of the difference in the Kelvin Scale, the 3000k vs 4000k vs 5000k lighting fixtures are not similar in appearance. Because of this difference, each type has its own applications.

3000K light gives a feeling of warmth, safety, and comfort. Therefore, many people love to put 3000K LED bulbs color in the house, especially in the bedroom and dining room. These devices will create a wonderfully relaxing space for you.

Next, LEDs emitting 4000K will be suitable for use in commercial environments, schools, and offices. This kind of light can highlight products and support promotion. In addition, it gives a bright background, improves concentration, and increases work productivity.

Finally, 5000K can increase clarity and accurately display things. Therefore, this type of LED bulbs works best in industrial areas and outdoor.

Blue Light

The Dangers of Blue Light Exposure
The Dangers of Blue Light Exposure

The amount of blue light that a light source emits might vary depending on the color temperature. Blue light is known to disturb sleep and create eye strain, particularly when utilized at night.

Because it can inhibit the body’s production of the hormone melatonin, the chemical that helps you rest and relax. Therefore, exposing to blue light at night will cause insomnia and disrupt the circadian cycle. So you should only use 3000K lights in the bedroom instead of 5000K.

The less amount of blue light is emitted by LED fixtures with a lower color temperature of 3000K, making them more comfortable to use at night. Blue light is moderately produced by leds of higher one like 4000k, which might be problematic if used at night.

As such, use a led with a color temperature of 3000K to reduce the adverse effects of low wavelengths from blue light on sleep and eye health at night.

Consider using lights with higher color temperatures during the day and switching to led fixtures with a lower one at night if you must use lamps with a higher color temperature, such as those of 4000K or 5000K.

Color rendering index (CRI)

Color rendering index is extremely important

You may have heard of CRI, which stands for Color Rendering Index. CRI is an index used to measure how accurately a light source produces in displaying the colors of things. This level of accuracy is compared to objects when placed under natural light.

The higher the CRI, the more accurately our eyes will see things.

3000K led will have a CRI in the 80 – 85. This figure shows that objects under the yellow light of 3000K will not be highly realistic. Meanwhile, 4000K LEDs usually have a CRI of 85 – 90, providing better accuracy. The color of things is most vivid when under 5000K lights because these devices often have a CRI above 90.

Which Is right for you: 3000k or 4000k

You have grasped the main characteristics and the difference between 3000K and 4000K color temperature lighting.

However, to choose the most suitable one, you must consider several factors. The main aspects you must consider include work purposes and personal preferences.

Because different color temperatures will cause different reactions in the body, choosing color temperature should be compatible with the intended use to avoid unwanted harm.

The cool white light the 4000K LED produces is neutral to create a luminous space, but not too stressful at all. It helps boost serotonin production, which has an uplifting effect on mood and emotions. You will always be full of energy when working under 4000K lights.

Also, 3000K stimulates your body to produce melatonin, which helps to relax and rest. Using warmer 3000K led bulbs in the bedroom will improve sleep quality, making you more comfortable.
