How Can the Kelvin Scale Help You Buy LED Lights? Technology Articles | March 19 Anthony Nelson Jersey , 2012
The Kelvin Scale is designed to help energy conscious consumers pick the right LED Lighting for their home. The principle behind it is very simple.


All light can be measure according to something called its 'colour temperature.' This is a basic characteristic of visible light and can be described on the Kelvin Scale by assigning it a ranging numerical value called a Kelvin Rating (K).


"Kelvin Ratings allow us to accurately describe the appearance of a light source in terms that are easily comprehensible by translating it into a numerical value that can be read on the Kelvin Scale."


Colour temperatures with a low Kelvin Rating are called warm colours, while those with a high rating are called cool colours. The Kelvin Scale can be used to define a whole variety of different types of light. For example, the temperature of midday summer sunlight is 5,500K, while the temperature of a candle is roughly 1 Mike Edwards Jersey ,750K.


The Kelvin Scale derives its name from the 19th Century physicist William Thomson, 1st Baron Kelvin, who once wrote of the need for an "absolute thermometric scale" of this kind.


Why do we measure light by its temperature? Colour temperature is determined by using a theoretical object called an ideal black body radiator, which absorbs and then radiates all the energy that reaches it. When the object reaches a certain temperature it gives off light, which makes the two interrelated.


Colour temperature plays an important role in a number of different industries Jamel Dean Jersey , such as photography, advertising and astrophysics. It can also help you choose a light bulb.


Not every light bulb produces exactly the same type of light. That is why we use the Kelvin Scale to help us choose the right light bulb, even if you can't see what the light source looks like.


LED Bulbs (such as GU10 LED) are typically available in two colour temperatures called Warm White and Cool White. Warm White bulbs closely resemble the light produced by traditional halogen bulbs and has a Kelvin Rating of 3,500K. Cool White bulbs are much brighter and sharper, producing a light with a Kelvin Rating of 6 Sean Murphy-Bunting Jersey ,000 Kelvin.


Deciding on which to buy is largely a matter of personal preference, but each also serves unique practical applications. Warm White is generally used for general illumination, while Cool White is used for light design, such as accenting and highlighting.
