LEDs are fast becoming the go-to source of light for homes and businesses alike, and it’s no wonder! They’re not only a great deal more energy-efficient than other, conventional bulbs, they’re also a great deal more versatile, giving you the ability to tailor the lighting ambience of your room using a variety of different colour temperatures. So, if you haven’t yet switched to LEDs and you’re unsure about LED colour temperatures, read on…
What Is LED Colour Temperature Anyway?
Colour Temperature, also known as CCT or “Correlated Colour Temperature” is actually a measurement a light source’s coolness or warmth as it’s perceived by the human eye.
As with temperature measurement in the physical sciences, it’s expressed in terms of Degrees Kelvin (K)
Thus, light sources with different colour temperatures are assigned a Kelvin Rating (K), which can then be read against the Kelvin scale as physical temperatures are read.
However, unlike normal scales, the Kelvin scale reads in the opposite direction, so light sources with high Kelvin Ratings of 5000 to 6000K will be perceived as cool, while those with a Kelvin Rating of 4000K or less will seem to be warmer.
Perhaps the simplest way to understand this is by visualising a Bunsen Burner (remember them from school science classes?). When a Bunsen Burner’s airflow is reduced, the flame becomes an orangey-yellow colour that looks warm.
However, if the airflow is increased, the flame becomes blue and appears colder – it’s all about our perception! The principle is the same with lighting colour temperature, although no physical temperature change occurs.
Although it’s not yet an exact science to which everybody adheres, here we refer to the different LED colour temperatures as “Warm White”, “Cool White” and “Daylight” as these terms enable people to distinguish easily between them.
Thus, our Warm White LED light bulbs have a Kelvin Rating of between 2700 and 3000K, while our Cool White models have a Kelvin rating of 6000K.
A 4000K rating is applied to our Daylight colour temperature, so it occupies the middle-ground between the two.
Take a look at the graphic, which gives the approximate values on the Kelvin Scale of each individual colour temperature.
Different Applications For Different Colour Temperatures
As you’ll have seen, the warmer the colour temperature, the lower the number on the Kelvin Scale, all the way down to candlelight, the warmest of them all. The ordinary, conventional Incandescent light bulbs we’ve used for years in our homes, emit only a muted, warm colour temperature that’s lovely for relaxing living spaces but not ideal for close work.
Unfortunately, these old-style bulbs can generate one type of colour temperature only, which limits their usefulness, especially in light (forgive the pun!) of LEDs’ amazing versatility.
At the other end of the scale, our Cool White (4000K) LEDs produce a form of light that’s much brighter and more penetrative – quite similar, in fact, to the light of a fluorescent tube light.
As such, Cool White LEDs can most often be found in light fittings in the kitchen, bathroom and work room, where close work and tasks are performed.
Daylight at around 4000K is the most naturalistic of the three colour temperatures, and the closest approximation of regular sunlight that’s achievable from an artificial light source.
Therefore, it’s perfect for providing a bright yet convivial ambience that’s perfect both for communal areas, and also for close work when accurate colour-perception is necessary. That’s why many people have begun to use it to illuminate their home office spaces and art studios.
Tailor The Ambience Of Your Rooms
Thanks to the unique versatility of our LED light bulbs, you’ll have the ability to tailor the lighting ambience of your rooms according to their functions. Therefore, prior to purchasing LEDs for your home, it’d be wise to decide:
- What do I use each individual room for? Relaxing and socialising or working?
- Will my fittings be providing general lighting or feature lighting?
- What kind of ambience would I like to create in each room? Relaxed and laid-back or clinical and clean?
- Is mine a starkly modern or a warm and traditionally appointed room?
Simply by asking yourself these questions, you’ll be well on your way to applying the perfect type of LED lighting for every room, every type of décor and every occasion.
