Choosing The Best LED Color Temperature – 4000k vs 5000k

The human eye has a different perception of color for different light color temperatures. The higher the color temperature of the light source, the more blue light is perceived, the lower the color temperature, the redder the light.

Normally people will perceive red, orange, and yellow light as warmer, and white and blue as cooler. Red has the lowest color temperature, then gradually increases to orange, yellow, white, and blue is the highest color temperature.

Different color temperatures have different effects on the human eye. In this article, we will help you differentiate between “4000k vs 5000k”.

What is light color temperature?

What is light color temperature_

LED color temperature is defined as the temperature of a black body whose radiation is the same color as that of tungsten. Color temperature is a measure of what color the LED light emits when it is emitted.

The unit of measurement for the color temperature criterion is Kelvin (K). Color temperature is not the temperature of the light source. Kelvin’s scale is from 1,000K – 10,000K.

LEDs with a higher color temperature will be LEDs with a cooler light. In contrast, LEDs with a lower K color temperature will show warmer colors.

#1. 3000k color temperature is a warm white light color

This type of light has a color temperature of 2500-3000K commonly found in incandescent, filament, and red-yellow light bulbs.

Light with low color temperature range, used in civil lighting.

#2. Neutral light

Light with neutral colors has a color temperature range of 4000K – 4500K. Using light with neutral colors gives a feeling of white light that is close to nature. This type of light is often found in fluorescent lamps, compact lamps, small-capacity LEDs, etc.

Application of neutral light in lighting in shops, restaurants, and large amusement parks.

#3. Color temperature 6500K is white color temperature

Cold light has a color temperature ranging from 5500K – 6000K, bringing natural colors with cold bright white color.

This is a light source from sunlight, the light of large-capacity led lights, and high-pressure lamps,…

Color temperature 4000K

The most common color temperature is in offices, shopping malls, or everyday residential outdoor lighting. It provides normal, brighter light.

Make people see the essence of things without overexposing them. Bright light can make people pay more attention and work harder.

It’s blue light damage will be slightly higher than the 3000K color temperature, but it can still be in an acceptable range, just need to pay more attention to give our eyes more rest, the temperature range 4000K color is also the widest application.

Color temperature above 5000K

Blue light color temperature above 5000K will be clearer because the light is whiter, and the light emitted is cooler.

Recommended for parking lots, industrial lighting, and other large outdoor venues, or some special needs requiring high-intensity lighting. We should not work at this color temperature for a long time, it is very harmful to the eyes.

Do 4000K LED bulbs emit light similar to daylight?

Do 4000K LED bulbs emit light similar to daylight_

It is not easy to compare artificial light with daylight. That’s because daylight is constantly changing. While the color temperature of the sun is close to 5800K, daylight can vary greatly.

As a general rule, the more orange/red the sky is, the lower the color temperature will be. And the bluer the sky, the higher the color temperature. In other words, daylight has a lower color temperature in the morning than at midday. For this reason, you will find that the light emitted by a 4000K bulb is similar to sunlight in the morning or early afternoon.

CRI represents the light quality of the lamp and directly affects the color and fidelity of the illuminated object. The CRI scale ranges from 0 to 100.

Any light with a CRI > 85 or higher is considered particularly good. Conversely, if the CRI is below 80, the light quality may be poor.

Compare 4000k vs 5000k

Each type of lamp has a different color temperature and is used for different spaces.

The 4000K lamp is suitable for commercial or showroom lighting.

The great feature of 5000K light is that it provides a fair balance between lost color sensitivity at lower color temperatures and blue aberration in 6500K and natural daylight.

For art studios that don’t use a lot of natural daylight, the 5000K LED will be able to work perfectly as the main light source.

Plus, 5000K LEDs can provide soft and relaxing lighting. Due to the reduced blue content, 5000K light can be more pleasant and balanced, making it suitable also for spaces in the graphic, printing, and textile industries.

Is 5000K brighter than 4000K?

Lumens are a measure of the brightness of a lamp. The higher this number, the brighter the light. What is decisive is the wattage of the lamp. The wattage determines the lumen, and the lumen determines the brightness of the light.

Both 5000K and 4000K can be used in different capacities.

For example, 60-watt and 100-watt LED bulbs can be used at 5000K or 4000K.

A 100-watt LED bulb at 5000K can have 1500 lumens. A 100-watt 4000K would also be 1500 lumens.

A 60-watt LED bulb at 5000K can have 750 lumens. A 60-watt 4000K would also be 750 lumens.

What is a good color temperature for the eyes?

Choosing the right color light for each living space and intended use is very important. Light with an inappropriate color temperature will directly affect vision and eye health.

What is a good color temperature for the eyes_

#1. Light color temperature for living room

The living room is the main space of the house, so it needs ventilation and natural light. So the light in the living room does not need to be too bright.

It is recommended to use light with a color temperature of 3500K to 4500K for comfortable and relaxing eyes.

#2. Light color temperature for the kitchen

Kitchen lighting needs to have a moderate color temperature so as not to confuse the ripeness of food.

At the same time, light with the right color temperature will give high color rendering, creating a good sense of sight and taste when using food. The recommended light color temperature for the kitchen is from 4000K – 6000K.

#3. Light color temperature for the bedroom

The bedroom is a place to rest and relax, so it needs soft and warm light. Lights with a color temperature of 2700K – 3500K will create a feeling of warmth, helping you to fall asleep easily.

#4. Light color temperature for bathroom

Bathrooms should use neutral lighting. Because there are mirrors and glasses in the bathroom space, there are often light reflections that are uncomfortable for the eyes. So soft lights have a color temperature of about 2700K to 4000K depending on the width of the space.
