The kelvin scale may seem complex-but it is easy to understand at its core!

It is simply a measure that determines the colour given off by light (in kelvins/k). The scale ranges from warm light to daylight to cool light; each of them being best suited to different environments.

So, what are the main differences?

Warm White

Warm white light has a yellow hue that almost imitates that of a sunset, thus creating a cosy, inviting ambience.

This shade of lighting stimulates the production of melatonin (the hormone directly responsible for the promotion of sleep). In turn, this maintains our bodies circadian rhythm (internal body clock), making warm white ideal for a bedroom or place of rest.

Our best-seller RetroLED Dimmable E27 4W LED Filament Pear Shaped Bulb Amber (Warm White 2700K) is 2700k which also makes it perfectly compatible with bedroom décor! Furthermore, due to the softness of the light, imperfections become less visible. (It’s like a real-life filter!)

Cool White

Cool white light (6000k) has a blue hue and is brighter and harder in comparison to warm white light.

Therefore, its use is most popular in an office or bathroom space as it can create a harsh environment in more relaxed areas of the home. This is because blue light suppresses melatonin production, disrupting sleep and consequently throwing off our circadian rhythms, making it incompatible with places of relaxation.

Since cool white is bright, it implements into professional settings well. Our OMNIPlus B22 6W OMNI-LED Clear Globe Bulb is ideal for these scenarios where lighting is needed to maintain an alert working environment.

Daylight

Daylight is a fusion of warm and cool white and so is neither too blue or too yellow in hue. As it possesses both qualities, it is perfect for the kitchen as it is pleasant in warmth but cooking tasks can still be done efficiently.

Daylight (4000k) imitates the direct sun so it is sometimes referred to as bright white. This allows for technical skills such as chopping vegetables to be completed without issue.

Additionally, the neutrality of daylight provides a natural finish by reflecting the light instead of absorbing it. The Eco-Rocket GU10 6W LED Bulb - 500 Lumens "The Ariel" achieves this effect for spaces in need of opening up.

What's The Best Option For You?

The answer to this question depends on the intended purpose for the light you’re buying. As mentioned previously, different temperatures of light suit their own respective settings.
