Facts about the Light:

While talking about the need and facts about interior lighting, you can easily get confused with various details. Therefore, you have to aware of interior lighting.

The intensity of light, color of light, or places can play a big part in the interior designing process.

Lighting can be derived from both natural sources like daylight and artificial sources like lamps or light fixtures. When indoor lighting is completed using various light fixtures, it can be an important part of interior design. The intensity, color of light, or places can play a big part in this designing process. Hence, as a good lighting planner, you have to know what is good for you.

Kelvin:

The Kelvin is the base unit of the measurement of temperature. The unit symbol of Kelvin in K. It is named Kelvin after the engineer and physicist William Thompson, 1st Baron Kelvin (1824-1907).

The Kelvin scale fulfills the requirements of its inventor as a thermodynamic temperature scale. The absolute zero is its null point. According to the scale, pure water freezes at the temperature of 273.15 K and boils at the scale of 373.15 K. This Kelvin is the primary unit of measuring temperature but is not written as a degree, unlike Celsius or Fahrenheit.

The light created by lamps has its own color. And the color temperature  may vary from 1000 K to 10000 K. Lower color temperature is represents the warm colors and higher color temperature represents the cool colors.  The color temperatures below the scale of 2800 K are known as extra warm white, while from 2800 to 3300 K is warm white and from 3300 to 5300 K is neutral white, and over the scale, 5300 K is known as daylight white, 6500 K is known as crystal white, as the temperature rises, the light increases.

Light has a powerful influence on both our mood and bio functions. The influence of light on our body is very powerful, as this topic is also known as “Human Centric Lighting”. It is an art of creating lightings that can copy the uses of natural daylight, which has a great impact on the functions of our body. The most powerful effect of lights on us is of course, vision. At the time of noon or during the early afternoon our bodies can remain active in the area of light color, but in the evening, our biorhythms need a low and feel-good light of low power. On the other hand, the warm and light color of candlelight gives you a romantic environment.

Lumens:

A very important factor about the light color is brightness. Lumens measures how much light you are receiving from a lamp or bulb or how much light is radiated from a light source. As the Lumen rises, it means you are getting a brighter light. Similarly, when the lumens reduces, it shows a dimmer light. Lumens can help you in buying the exact amount of light you want.

A very important factor about the light color is brightness. Lumens measures how much light you are receiving from a lamp or bulb or how much light is radiated from a light source.

The unit “Watt” reflects the usage of a lamp. The energy a light source consumes can be reflected as the measurement per kilowatts per hour. But the best value of brightness is Lumen (Im).

Lux:

The light intensity is measured to realize if a particular light source is providing enough light or not. Illuminance is the metric that helps in measuring the intensity of light within a specific space. This amount of light is measured in the unit called Lux. Measuring the accurate amount of light helps you to evaluate if you are getting sufficient light for the need to complete some special visual tasks or not.

Illuminance is the metric that helps in measuring the intensity of light within a specific space. This amount of light is measured in the unit called Lux.

This can ensure that you don’t damage your eyes while working in places that have insufficient illuminance. The number of Lux becomes less if you are getting further away from a particular light source.

These are some basic but very important aspects to get the light which is perfect for both your home and your good health.
