What Does 2700K on Your Light Bulb Tells You About

 

Most bulbs will tell you its color temperature on the package, for example, 2700K, which will indicate the tune (how warm or cool) the color of the light is. How does the “color temperature” translate in regards to what 2700K light looks like? Let’s take a look at it.

What is 2700K 

 

 

“K” following 2700K refers to Kelvin, which is a color temperature measuring unit, and 2700K stands for 2700 degrees Kelvin. Light appearance is measured in temperature using the Kelvin scale. 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. 

 

 

The term 2700K is not pertinent to brightness but refers to the color temperature that varies between white and yellow. In contrast with outside weather, lower color temperatures imply warmer colors of orange and yellow, while cooler colors such as white and blue have higher color temperatures.

 

 

What Color is 2700K

 

 

“Is it warm white or cold white?” is an often-asked question inquiring the color temperature of the LED. A 2700K LED provides a warm, near-golden white light. 

 

 

To answer this question, we have to bring about Kelvin Color Temperature Scale. The Kelvin Color Temperature Scale is utilized for the visual appearance of different light temperatures. It is measured in Kelvin (K) degrees, generally between 2700 to 5000 Kelvin degrees.

 

 

The following Kelvin scale gives you an overview of the several typical temperature ranges in house illumination. The lower the number, the more the hue is “warmer.” The color temperature grows cooler when the number increases in the scale. This doesn’t imply that the air temperature in the room truly changes, but goes from the “coziness” ambient LED light on the left to a feeling like a blue sky on the right.

 

 

 

 

How Bright is 2700K 

 

 

As mentioned above, 2700K is not about 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 2700K can vary in different situations.  

 

 

 

 

Application of 2700K 

 

 

In brief, if you prefer the color of the traditional incandescent bulb, 2700K is your color temperature. 2700K offers a very pleasant environment and is the ideal choice for you to create a relaxing vibe in your living rooms and bedrooms. However, not everyone finds himself or herself a fan of the 2700K incandescent bulb color, and some locations and venues could indeed benefit from a higher color temperature, as in better visibility. With 2700K light bulb, your place can appear quite yellow or orange, such that everything seems to be “washed out” with a yellow hue, which is a great choice for living rooms and bedrooms, but not a pleasant lighting for task-oriented areas such as office, kitchen, and public venues, in which cases, you may want to consider 3000K as an alternative. The reason has been explained in the following paragraph. 

 

 

2700k vs 3000K

 

 

2700k vs 3000K are both warm white color. However, visible differences in their color temperatures still can be seen in the figure below cold and blue. And these differences will help you decide which one suits your room the best.  

 

 

A 3000K light, with its color is a neutral white, is slightly purer compared to a 2700K light. Less yellow or orange shade can be found in 3000K, but more. For example, Halogen bulbs, if you are familiar with, emit the light color of 3000K. The following image depicts the difference between 2700K and 3000K.

Although the differences between 2700K and 3000K light bulbs are visible, they are not extremely evident. The difference is only easy to see if you place these two light bulbs beside each other. But if apart, like say, one is on a different floor from the other, you will not realize the difference without special attention.
