What Is LED Colour Temperature?

LED Colour, in most cases doesn’t mean RGB colour, such as red, blue or yellow. When we talk about Colour Temperature, we are referring to the Bulb ‘Colour Temperature’. 

The Colour of light that is emitted from an LED Bulb is known as the Colour Temperature. It’s not about how ‘hot’ the bulb becomes, but rather the colour of the glow that the LED generates. The most common Colour Temperatures are Warm white, Natural white and Cool white.

Understanding The Basics Of Colour Temperature

First of all, we need to understand the basics. 

The Colour Temperature of light is measured in Kelvin (K) and classifies light into Warm, Neutral or Cool tones for Bulb lighting. 

However, what do these temperature categories imply for your lighting options?

What is Kelvin?

A light’s Colour temperature is measured in degrees Kelvin (K). Kelvins range from 1900K to 6500K.

The Kelvin Scale runs in the opposite direction to the temperature scale; the Warmer the colour, the lower the Kelvin rating.

For example, a Warm light will have a low Kelvin rating of 2700K with a Yellow/Orange glow. 

A Cool light will have a high Kelvin rating of 6000K or and omits a blue/white glow.

Matching Colour Temperature To Your Lighting Needs

Now that you understand the basics of Colour Temperature, let’s discuss below how to match it to your specific lighting needs.

Home Lighting: 

In your home, consider Warm Lighting for areas where relaxation is key, like bedrooms and living rooms. Opt for neutral lighting in kitchens and workspaces for a balanced, productive environment.

Retail and Commercial Spaces: 

Retail stores often benefit from Cool Lighting to make products appear vibrant and appealing. However, changing areas or lounging spaces may benefit from Warm Lighting to create a comfortable shopping experience.

Outdoor Lighting: 

When illuminating Outdoor spaces, consider the purpose. Cool Lighting is ideal for security and visibility, while Warm lighting can add a welcoming touch to patios and gardens.

Dimming and Adjustability: 

We also recommend Dimmers and adjustable fixtures are essential for fine-tuning your lighting Colour. They allow you to customize the ambiance for various activities and times of day. For example, you can start with bright, Cool lighting in the morning for a productive work atmosphere and transition to Warm, dimmed lighting in the evening for a cosy, relaxed setting.

Should I go for Warm White, Neutral White Or Cool White?

Here is our recommendation below:

When Should I Use Warm White Bulbs or LED’s? 

  • A Warm white should be selected for spaces that benefit from a cosy ambience such as Living Rooms, Dining Rooms and Bedrooms or Restaurants and Hotels.

 Neutral Bulbs or LED’s? 

  • A Neutral bulb should be selected for spaces that benefit from a visual tasks that requires more concentration, such as using computer or reading. This could be used in the Kitchen or Home Office.

Cool White Bulbs or LED’s? 

  • A Cool White bulb should be selected for spaces that have large areas and would benefit from very bright lighting, such as a Dentist, Retail Store, Grocery Store or large commercial Office.
