is rapidly replacing incandescent and fluorescent lights in almost every sector, be it commercial or industrial. This is because they provide better illumination and higher energy savings along with several other benefits. However, before deciding on for business, there are three important things that one must understand i.e. CRI, CT, and foot-candle.
The above mentioned are the most relevant and vital determinants
of low or high-quality light. To begin with, CRI stands for colour rendering
index and CCT stands for correlated colour temperature (also known as colour
temperature for several lights). Then comes the foot-candle, which is commonly
referred to as the measurement of the amount of light hitting a target space.
Now, let us talk about the three measures in detail so that one can better understand how they influence the quality of lights and help achieve energy-efficient lighting solutions.
1 Color Rendering Index (CRI):
CRI is the measurement of light’s ability to showcase the actual colors of a product when compared to natural light. Lights that have high CRI are considered to be more appropriate for a commercial space. However, in the end, it depends majorly on the required application.
For instance, most retailers in
malls know exactly how to showcase their products offerings in front and
centre, leading to an increase in sales. Here, the colour rendering index of
your lighting plays a huge role in influencing purchasing decisions. It can
influence consumers and buying impulses.
2 Colour Temperature
Colour temperature is a way of describing the characteristics of visible light from several emitters. It depicts the warmth and coolness of light. Warmer light is more yellow and cooler is bluer. Furthermore, both LED lighting and fluorescent lights come under this category and can be evaluated by using CCT.
Lights that have ratings on the lower end of the scale (~2000K) are often referred to as “warm” (usually they are red and yellow colours) and those at the higher end of the scale (5000K+) are referred to as “cool”(usually white to light blue). It is the same for colour temperature scales.
It is a specification that is used to describe the most dominant colour tone for the non-blackbody light emitters such that they can be fairly compared and contrasted with the light emitters that on the other hand do approximately emit blackbody radiation.
A foot-candle is a measurement of the amount of light that reaches the targeted area as compared to the total amount of light coming through the source. It is measured in Lumen per square as measuring in lumen (alone) is considered to be deceiving as the light that is illuminating the non-targeted area is not being productively used.
We at Wipro lighting understand that deciding on an appropriate can be cumbersome. Thus, we intend to provide the safest and most efficient commercial lighting solutions that align with your business's needs and requirements. They not only boast a robust built and aid monetary savings but also help in building a productive environment.
