How to Light

How do I choose the correct colour of LED?

LED lamps and luminaires are commonly available in 2700K, 3000K and 4000K colour temperatures, but how do you go about choosing the correct colour?

Lamp colour temperature is often a personal or historical choice and it depends on what environment is being created.

 

 

 

Here is a general guide:

2700K is a similar colour appearance to incandescent lamps and is a warm, relaxing colour.

3000K is a similar colour appearance to halogen lamps with a warm but crisper colour than 2700K. Commonly called ‘warm white’.

4000K is a cooler, whiter colour than 2700K and 3000K. It’s the lamp that has traditionally been used in offices, waiting areas and most commercial applications. This is commonly called ‘cool white’,  or occasionally ‘neutral white’.

6500K is a very cool white that is used to simulate day light. It is also said to increase productivity when used in a work environment. It is commonly referred to as ‘daylight’.

The warmer colours work well in more relaxed environments with warmer colour decoration such as in domestic living rooms, restaurants and hospitality areas.

The cooler colours work well to help create a lively environment with lighter colour decoration such as domestic kitchens, offices, warehousing and in retail spaces.

Now that we have the ability for colour ‘tuning’ via LED sources, the extremes of warm and cold white sources are being used as the basis for ‘human centric’ lighting installations. Mixing of the two extremes allows interior lighting schemes to be adjusted according to the needs of the occupants.
