Which is better; 5000k or 2700K? While some of you may not know what I am talking about, the color of light you have around you can drastically alter the view of the world around you. It can even alter your mood! Colors have an impact on your mood as does light or more importantly a lack of light. During the long winter months when heavy grey clouds set in, people can feel depression due to a lack of bright sun light. I know I enjoy a sunny spring day more than a cloudy winter day!
To understand my original question, 5000K or 2700K, which is better? You need to have a basic understanding of the Kelvin scale. The K in 5000K stands for Kelvin, named after British inventor William Thomson, also known as Lord Kelvin. William Thomson developed a scale that helps us measure the color of light. With regard to lighting, the Kelvin scale ranges from infrared light not visible to the naked eye all the way to Ultra Violet light, which is also not visible to the naked eye. Light that is visible to you and I is found in between the two ends of the spectrum. The Kelvin scale includes Gamma Rays, X-Rays and Radio waves, but today I am focusing on the light portion of the scale.
The numbers before the K in 5000K describe the range of color. For instance, 2700K colored light is a yellowish light similar to the traditional incandescent light bulb. Most people prefer ambient room lighting in the 2700K – 3500K range. Typical work lighting is in the 4100k to 5500K range. This range helps the worker see more detail while not being too harsh on the eyes. The 6000K – 7000K range is a light that is blue to purple in color and is often found on new car headlights or low end import work lights. When it comes to work site lighting, it is important to choose a work light with your preferred color of light. Having the right colored light will make your work easier. Most people I have talked to prefer a work light with a bright white color in the 4700K to 5200K range.
So, back to my original question. Which is better; 5000K or 2700K? The best answer is: It’s up to you and what you are doing!
Have a great day and may it be filled with your choice of light!
