You may have heard of a 6500K light. However, what does it mean? How do the “color” and “brightness” translate in regards to what 6500K light looks like? This is a breakdown of the term 6500K.

What is 6500K 

Actually, K refers to Kelvin, which is a color temperature measuring unit, and 6500K stands for 6500 degrees Kelvin. This term is not pertinent to brightness but refers to the color temperature that varies between white and yellow. Lower values, for example, 2700K, would produce yellow light. The higher the Kelvin value, the whiter the light is.

Since Kelvin refers to a unit to measure color temperature, what is color temperature? Color temperature refers to the temperature that fits the thermal radiation distribution with the light emitted by a black body. Thus, more or less a tempo of 6500K indicates that if a black body was heated to 6500K, the tube of the light and the black body would be the same in color, while 6500K is a favorable light hue because it seems to human eyes to be “most natural”.

What Color is 6500K

6500K appears as pure white, which is very close to natural daylight white on a cloudy day. To further clarify it, the color temperatures between 4000K – 6500K may remind you of the sunlight at noon. While the LED lights may be manufactured to emit colors in different tones, from white light to cool blue light. In this sense, a 6500K LED light would give you exactly cool daylight. 

How Bright is 6500K 

As mentioned above, 6500K is not pertinent to brightness. What determines the brightness of a bulb? The brightness (luminosity) of a bulb depends on both current and voltage, which is related to whether the bulb is in parallel or series. Besides, the overall luminosity is partially determined by the type of bulb and the light output ratio of the device. In a nutshell, the brightness of a lamp is irrelevant, the important factor is how much light reaches the illuminated surface. Therefore, the brightness of 6500K can vary in different situations. 

Quantity of 6500K Light

The lights of 6500K have a high level of radiance. The illuminance level is measured by the light quantity reflected on a plane surface. The needed light intensity depends on where your 6500K light is being used. The minimum level necessary is often about 500 lux (what is illuminance level: a common photometric quantity used to determine the brightness of an area, which is not a transmitted quantity of the light source but a received quantity. 

Application of 6500K LED 

Looking for a cool white light that calms the environment down? Then 6500K color is the right choice for you. It’s worth noting that 6500K LED bulbs can help you to gain a good concentration in workplace environments without being fatigued. Besides, 6500K light may be utilized elsewhere, such as the study room and kitchen, where the activities you undertake require full attention from you. In the storehouse and police station, 6500K is often used as safety lighting. For presenting precious items in exhibitions and boutiques, you can also find the utilization of 6500K.  

5000k vs 6500K

When it comes to “daylight” or color-balanced LED lights, two different color temperature options: 5000K and 6500K may frequently appear in pairs. Which one?   

First, what are the differences between 5000K and 6500K? Relatively, 5000K appears to be more yellowish, while 6500K looks more bluish. 

Due to the time of day, season, weather, and geography, it is true that the color of natural daylight can be dramatically different. However, 6500K is still commonly recognized as the most representative color that matches natural daylight. Therefore, if you are looking for a blue-sky light, go for 6500K!
