Warm White or Cool White? Choosing a Colour Temperature for your Lighting

One of the great things about LED lighting is that you can now pick the colour of light generated by your light bulbs. This was not possible with incandescent light bulbs, which could only generate a very warm, yellowish hue. Colour is important, because it sets the mood of the area illuminated by light.

The appearance or colour of light is measured using kelvins (K), ranging from 1000K, very red, to 10,000K, very blue.

In reality, the Kelvin Scale goes far beyond these numbers, but the central idea remains: the higher you go up the scale, the more the light resembles daylight.

This is known as colour temperature, which doesn’t actually measure the actual temperature of a light bulb, but rather the colour it produces. 

Which to Choose? Variety is the spice of life, and choice of which colour temperature to pick when buying light bulbs is entirely up to you. If you like the yellow globe of conventional lamps, then go for bulbs with a temperature of 2700K to 3000K. For a cleaner, more modern look, a cool white bulb with a rating of 4000-5000K is for you. 

Applications Still, there are some rules you can follow if you want to create the right mood with your light bulbs. Here are some examples of specific colour temperatures and where they’re best used. 

Warm to Warm White Bulbs – These are best used in hallways, living rooms, and bedrooms. You want relaxing lighting, but not something too warm that you might get drowsy. 

White to Cool White Bulbs – Cool white bulbs are best used in spaces where your full attention is required. Think kitchens, studies, office spaces, and more. 

Daylight Bulbs – Their bright, sparkling light makes the perfect for retail spaces, art studio, and other commercial areas. For an in-depth look at colour temperatures in lighting, hit this link.
