Warm or Cold Light

Choose light to illuminate your home is very important, it requires care and attention, for its location for the type of light, hot or cold.

It seems strange to say but usually when it comes to light we talk about heat, in factwe tend to associate the two probably because if you think about light the Sun and if you think the Sun is expected to heat.

Modern technology allows us to make a distinction between warm and cold light, a distinction that before when there were only incandescent bulbs, now out of print,was no.

With incandescent light bulbs, the only alternative was the warm light, due to the shade of red date from the very functioning of the bulb.

Now with Led bulbs, we have the opportunity to select the color temperature of the lights that we prefer.

What is color temperature?

The colour temperature enables us to differentiate the hue of the light emitted by the bulb and is measured in degrees Kelvin. A measurement example to understandthe intensity of the light can be made to the daylight of the Sun exceeds 5000 degrees Kelvin. The color temperature is used a lot, both in lighting technology which in photography.

Depending on the temperature of the light bulbs used, our eyes perceive based on the brightness of the light, a light as hot or cold, this perception will vary according to its nuances.

For warm light, we mean a light that has a low color temperature, less than 3300 K and presenting nuances that can vary from reddish to Orange, to yellow, to white hot. With the temperature of 3000 degrees Kelvin is talk of real warm light. At 3550 degrees Kelvin the light is warm but his color will be whiter, this may be termed neutral light, until a colour temperature range between 3500 and 4000 degrees Kelvin.
If the color temperature is between 3600 and 6500 degrees Kelvin, we speak of cold light, the color of which tends to white and bluish. These blue and blue nuances will enable us to detect light, associating it to a cool shade.

In common use the pure ice, if you associate a color temperature of 5000° Kelvin white assumes that while at 6500 degrees K binds a bluish light.

How do you classify white light bulbs

The white light bulbs, are classified by following State classification in the UNI 12464.

We speak of warm white light, if the color temperature is less than 3300 degrees Kelvin; Let’s talk about neutral white light, if the color temperature is between 3300 and 5300 Kelvin;

We talk about cool white light, if the color temperature is over 5300 Kelvin.

Which one to choose: warm or cold light?

Usually, the warm white light is used for the interiors of offices or houses, while the cold white light, we find it in the great outdoors to the public, such as supermarkets.

Even the colour of light is important if we approach to shades of red, so we’re talking about lower temperatures, warm light also called warm-light, while with higher temperatures and tendency to talk about cold or cool light blue-light.

With regard to the choice of the color temperature of light bulbs there is a universal criterion, each can be based on your preferences and the needs of ambient light to be illuminated through LED bulbs known on allpubliclibraries.

Obviously in household environments you prefer a hot light bulbs because it gives more familiarity and intimacy to the environment itself.

By man the warm light is perceived as soft and enveloping, that cold as tough and sharp, in fact the latter is often used in studios and offices.

The cold light you associate a feeling of cleanliness and order why we might also find used in environments like the bathroom.

The choice also depends on the type of furniture, in fact in a House decorated in a modern way, with metallic surfaces or shiny, cold light may enhance the choice of furniture.

If you are using a cold light important is not reaching a color temperature is too high, this in order not to create shadows too sharp and hard, that could create an uncomfortable condition to those who live in that environment.

Then choose the warm or cold light is something strictly personal, important though always consider energy consumption that comes with it.
