Guide: IRC "Chromatic reproduction index" and LED lighting

LED LIGHT QUALITY = HIGH CRI

LED lighting, because of its efficiency and the energy savings it entails, is becoming more and more widespread. Now, when we want to reduce the power consumption of the home or commercial premises, most of us know that we need to replace bulbs and lighting in general with LEDs. But when changing incandescent or halogen bulbs, switch to LED will change the quality of the light we used?
Most LED lighting comes in 3 color temperatures (cold, neutral or warm). The incandescent bulbs are normally very hot, and to get the same warm light, you will have to choose a warm temperature LED bulb too. Like a 9W LED bulb with a high CRI.
There is also another factor to consider. If we want colors and objects, in general, to be radiant and lively, especially for shops, shops or premises where it is important that objects be highlighted.
It is therefore essential to have LED lighting with a high Chromatic Rendering Index (CRI).

WHAT IS THE CHROMATIC RENDERING INDEX: IRC?

guide of irc

The Color Rendering Index (CRI) describes how a light source reveals the color of an object with human eyes. And how subtle variations of tone and shades of colors are revealed.
The IRC is a scale from 0 to 100: the higher the IRC, the more accurate the color spectrum is. Incandescent bulbs are considered the reference light and have a CRI of 100.
All different light sources have different CRIs. These are comparable to the light quality of incandescent bulbs. Fluorescent light sources and LEDs vary between 75 and 85, some LEDs can reach a CRI of 90.
To conclude, things will look different depending on the CRI when turning on the light bulb.

Below, the IRC of LED very high and that of a conventional LED:

The higher the color rendering index of an LED bulb, the more expensive it will be since a high CRI makes the colors more radiant, vivid and attractive. And it generates a much more beautiful and professional light.
High CRI = more sales!
On the other hand, a lower-cost, low-cost CRI bulb diffuses light with poorer, pale, yellowish colors.
The CRI of fluorescent lighting is generally below 70%, which is a poor result.
An IRC index> 80 is considered very well.

If the bulb is used in a professional or commercial context where the appearance of objects and products is very important, high output bulb bulbs with External Driver are ideal. It has a high CRI and has an external drive. This allows him a continuous and long-term use as in the shops. Its price is a little higher than that of bulbs without an external driver. But it's a bulb that will last a lot longer. And that generates a much higher quality of light.

UGR or glare rate of discomfort what is it? How to improve it?

  What is the UGR or glare rate of discomfort? Here we explain all the concepts to master on the subject. WHAT IS GLARE? Glare is a feeling of discomfort caused by the presence of bright flashes of light in the field of vision. This is particularly the case when we look at a bulb directly or the reflection of the sun on the surface of the water. the reflection of the sun on the surface of the water. There are two kinds of glare: disruptive glare and uncomfortable glare. The first consists of the appearance of a luminous veil causing a blurred vision and a decrease in sensitivity to contrasts, which disappears with the cause of glare. A good example of disruptive glare is caused by the long-range lights of vehicles that pass us when we drive at night. The second, uncomfortable glare, consists of a sensation of visual discomfort produced by a too intense luminosity, causing certain visual fatigue. The latter is the most common cause of dazzle indoors, on which the UGR is...

DIFFERENT COLOR TEMPERATURES OF THE LED LIGHT: LEARN HOW TO USE THEM.

Image
In decoration, we take into account different parameters to define which elements to use depending on the effects we want to create. In this range of possibilities, white light is essential to achieve the desired goal. However, it must be taken into account that the emission of light LED devices, lamps, bulbs, spots, etc. is not the same. The color of the light or the color temperature varies according to 3 tones measured in degrees Kelvin. The warm light is below 3,300 Kelvins. The light stiff between 5,000 and 6,500 degrees Kelvin. In an average of 4,000 degrees is neutral or natural light.  It is used to produce a sensation of cleanliness and freshness. WHAT LIGHT WHITE USE? WHEN AND HOW TO USE IT? As explained above, each tone of light has an appropriate use according to the atmosphere and the sensation that one wishes to create. The hot luminaire is ideal for creating warm and welcoming atmospheres. The cold light is mainly used in places where there is a lot of m...
