Confused between warm and cool LED lights? Choose 4000K lights to get a perfect balance between the two!

The neutral hue of 4000K LED lights makes them suitable for versatile applications. They provide a comfortable ambiance for both residential and commercial spaces.

Let’s explore the ins and outs of 4000K lights and learn when and where to use them:

What Are 4000K LED Lights?

The ‘K’ in 4000K stands for ‘Kelvin’, the measuring unit for CCT. So, 4000K LED light refers to the color temperature of the light. It brings a perfect balance between warm and cool light. The neutral white illumination of 4000K makes it suitable for multiple applications.

How Do 4000K LED Lights Look Like?

The hue of 4000K LED lights is similar to the direct sunlight of morning and afternoon hours. This falls between the color temperature range 2700K/3000K and 5000K/6500K. So, you can say the light of 4000K looks like something in between the warm white and cool white. It has a light, warm tone but not too yellowish. Again, it’s not as bright as daylight.

Is 4000K Similar to Natural Daylight?

Natural daylighting is fully dependent on the sun. However, though the sun has a constant color temperature of 58000K, it appears different at different hours of the day.

The color of the sky, clouds, weather, and other environmental conditions have an impact on natural daylight’s appearance. For instance, at midday or noon, the sunlight will have a color temperature of around 5000K. But when you consider the entire sky on a clear day, the color temperature will appear closer to 6500K. Therefore, it’s tricky to compare 4000K of artificial light source to exact natural daylight.

Nevertheless, sunlight in the morning hours  (9:00 AM) and afternoon ( 4:00 PM) brings a similar effect to that of 4000K LED lights.

However, color temperature alone can’t decide if the light is similar to natural daylight or not. You must consider CRI for that. It refers to the artificial light source’s color accuracy compared to natural light. CRI is graded from 0 to 100. A higher rating means better color accuracy. The 4000K LED light must have a CR 90 or higher to mimic natural daylight.

4000K Appears Too Blue Or Too Yellow?

4000K is neither too bluish nor too yellowish. It has a neutral tone that comes closer to the sunlight. Compared to natural sunlight, 4000K seems more yellowish. So, it’s unlikely to look too blue.

However, the appearance of 4000K or any other light depends on your eyes’ adaptation to ambient lighting. For instance, the 4000K LED light will appear more yellowish when you enter the room coming from outside during daytime. The daylight is bright and has a color temperature of around 6500K. So, when you are outside, your eyes have adapted to this bright light. As you suddenly get to a room with 4000K, it will definitely feel too yellow. But if you enter the same room coming from outside at night, the light will not look much yellowish.

Again, suppose your bedroom has a 3000K LED, and you installed a 4000K LED for the living room. Now, as you enter the living room from your bedroom, the illumination of 4000K will look crisper. This is because 3000K is more warm and yellowish compared to 4000K. But does it mean the 4000K will appear blue? No, it will look crispy and less yellow than 3000K but not blue.

Therefore, the illumination of the same 4000K appears different at different times.

4000K Vs. Other Color Temperatures of LED Lights

4000K vs. 3000K LED Light

The hue of 3000K is more yellowish than 4000K. For its greater warm tone, 3000K feels more cozy and relaxing than 4000K. You can use 3000K for the bedroom as it’s more effective in improving the sleep cycle than 4000K.

However, in spaces where too warm a tone is not appropriate, going for 4000K is better. For instance, in your bedroom, you have a reading space and a vanity too. Installing 3000K LED lights, though good for relaxing, is not appropriate for tasking. In this case, going for 4000K is safer.

4000K vs. 5000K LED Light

5000K has a bluish-white tone compared to the soft-yellow glow of 4000K LED light. You can easily detect their difference with your bare eyes. The illumination of 5000K is bright and ideal for commercial lighting. You can use them in showrooms, stadiums, art galleries, garages, and workspaces that need bright light. On the other hand, 4000K is more appropriate for residential lighting.

4000K vs. 6500K LED Light

6500K LED light mimics natural daylight. It is a very cool white light creating crips and bright illumination. Compared to 4000K LED lights, they provide a more energetic mood and alertness. Using these lights in residential spaces is not ideal. They are too bright, and the bluish tone of the lights will hinder your relaxation. However, 6500K LED lights are best for applications that require high visibility and color accuracy. You can use them for task lighting, photography & digital studio, hospitals, etc.
