2700K vs 5000K Lights: What’s The Difference Between?


2700k light is typically used in lamps found in homes and bedrooms, while 5000k is more commonly used for industrial purposes like factories. Also, people will find that 2700k provides more balanced illumination overall. This type of light is great for reading, working on computers, or studying. 5000k light is popular in large area coverage and sports because it’s brighter and more visible. It’s perfect for areas where you want to make a bold statement.

Still, there are some key differences between 2700k vs 5000k light bulbs. Today, we’re going to explore them in more detail below.

2700k vs. 5000k – What is the difference?

Before we go through the differences, it’s important to know what the K( Kelvin) means here. For your kind information, Kelvin is a unit of measure that is used to define the color temperature of light bulbs.

It was first proposed in 1848 and is named after William Thomson, also known as Lord Kelvin, who proposed it as a way to compare different colors without using words like “dark” or “light.”

Lightbulbs with a higher kelvin rating are typically used for colder temperatures, such as in kitchens or bathrooms. These bulbs produce a colder tone than those with lower kelvins and can be more efficient when using less energy. 

2700k and 5000k are both popular light bulbs. They produce different amounts of light and serve different purposes. Let’s now see some common differences between 2700k vs 5000k light bulb:

Colour of the light:


2700k light bulbs produce a warmer, yellow tone of light. On the other hand, 5000k bulbs produce a brighter blue-white light. This can be useful when you need to see things better in a brightly lit area or if you have sensitive eyesight.

Light quality:

Both types of lights are great for various purposes, but they offer different levels of brightness and color quality. 

2700k is typically better balanced in terms of illumination than 5000k, making it preferable for general use such as reading or in a restaurant for a warm environment.

In contrast, 5000k bulbs are usually brighter and offer a pure white light which is perfect for high-end lighting applications like showrooms or commercial environments.


The cost of 2700k and 5000k light bulbs differs depending on where you buy them. In most cases, the higher kelvin rating means that they are pricier than standard bulbs.


2700k bulbs are typically warmer than 5000k bulbs. This is because 2700k emits a more muted light, whereas 5000k produces a brighter, whiter light. Whilst this may not be an issue for some people, others might prefer the warmer feel of 2700K bulbs.

To understand which light bulb is right for you, it’s important to consider your needs and preferences. If you’re looking for a warmer tone of light, then 2700k might be the better option. 

On the other hand, if brightness or pure white color quality is more important to you, 5000k bulbs may be a better choice.
