Colour Temperature

The difference between 2500K and 4000K, and what it means.

 

With most lighting products on our site, the colour temperature is often an important factor in deciding which light is best for you. The colour temperature is measured in Kelvin (indicated by a "K") and ranges from 1700k which is a "warm" end of the spectrum upto 10000K which is the "cool" end of the spectrum.  The higher end of the kelvin rating, (towards 10000K) results in a light with a blue tint to it, as the scale hits 10000K, it is as close to Sky Blue as possible. Traditional lighting does not reach this extreme end of the scale.

But Kelvin is a unit of temperature measurement?

In an old incandescent or halogen bulb, the Kelvin scale referred to the temperature of the element and the associated colour it produced. In LED's the Kelvin rating is to simply indicate the colour of the light by the temperature previously associated with the halogen bulbs.

Can i pick a lamp/bulb from any colour in the Kelvin scale?

The lighting we sell ranges from 2700K Warm White, through 4000K which is commonly known as Cool White, upto 6500K which is known as Daylight. There can be some difference in the naming of these, per to the manufacturer, but this should more or less applicable to every brand we sell.

Uses

In the home, a Warm White (2700K) end of the spectrum has a warm yellow light to it. It is most commonly used in Living Rooms, Bedrooms and Hallways.

The Cool White (4000K) is a Whiter light that is more used in utility rooms such as the Kitchen and bathroom. 

Daylight (around 6500K) produces a brilliant white light with a blue tint that is used for working environments amongst other uses.
