When you choose LEDs to light your home, what you’re actually choosing is energy-efficiency, longevity and versatility. LEDs come in a number of colour temperatures, so read this LED Monkey guide to choosing the right one!

Why Are LEDs Able to Generate Different Colours?

Old-fashioned incandescent and halogen light bulbs can usually only generate one colour. However, LEDs are available in a multitude because of the materials they’re made from.

That's right, semiconducting materials like Aluminium gallium indium phosphide (AiGaInP) and Indium gallium nitride (InGaN), enable LEDs to emit certain colours depending on their levels in the manufacturing process.

Passing an electrical current through the former creates reds, oranges and yellows. The latter, however, will emit greens, blues and, the subject of this article, whites.

Different combinations and amounts of materials used in the manufacturing process will result in different colour possibilities. So, you’ll understand why certain LEDs come in a single colour, while others can recreate the entire colour spectrum.

While there are no hard-and-fast rules to the names of the colour temperatures, here at LED Monkey, we categorise them as follows:

  • Warm White – 2700 – 3000K
  • Daylight – 4000K
  • Cool White – 6000K

Each colour temperature has its own place on the Kelvin Scale that’s usually used to denote physical temperatures. So, how might you go about choosing the right one for your purposes?

Why Choose…

Warm White?

Measuring between 2700 and 3000 Kelvins, warm white colour temperature is the closest approximation of the traditional incandescent light.

This makes it the most popular of all the colour temperatures, appealing as it does to the traditionalist in us.

As you’ll see from the photo above, warm white casts a cosy, convivial glow. This makes it perfectly suited to the British living room, especially after you've spent a long, stressful day at work.

That’s why most of our customers opt for warm white LED bulbs for their bedrooms and living spaces. And, it's the reason they’re amongst our very best-selling products.

Cool White?

Measuring around 6000 on the Kelvin scale, Cool White is a much brighter and more penetrative colour temperature, and one  that will help give your room the modern, clinical look that’s so popular right now.

The closest approximation of true white light that’s currently available, you might notice that Cool White light has a very slight bluish tinge to it.

Because of these qualities, Cool White LED Bulbs are best suited to task-centric areas. These include spaces such as the bathroom, kitchen or studio as it’s a great type of light for close work and will aid dexterity and concentration.

Quite often, the Cool White colour temperature can be found illuminating home office areas too, given its ability to make a space feel modern, open and airy.

As such, it’s used by slightly less traditional people, seeking to create a modern, minimalist haven in an otherwise chaotic world.


At 4000 Kelvins, Daylight (sometimes known as “Daylight White”) occupies the middle-ground between the other two colour temperatures.

It combines the relaxing conviviality of warm white with the bright and clinical feel of cool white.

As such, it’s the closest artificial approximation of natural daylight. It's actually an ideal choice for virtually any type of environment.

Possibly the only reason more people aren’t using it in their homes is that they’re not yet aware of it!
