Plain Sunlike Tunable White Achieves UGR<19 and CRI>97 

 

It is proved that quality lighting has beneficial effects on :

  • circadian biorhythm
  • visual comfort
  • daytime alertness
  • mood
  • sleeping quality, and more.

When speaking about quality of light, we have to observe the following key factors to achieve well-being and a comfortable indoor environment: glare prevention, colour rendering, lighting uniformity, illumination level and a harmonious distribution of brightness.

 

 

If we take a closer look to colour rendering, an accurate colour and texture reproduction of objects is crucial in indoor applications, where colours need to be shown as close as under the sunlight. This may be vital, especially for printing houses, fashion stores, galleries, dental clinics, graphic design studios, fine jewellery stores, etc. Last but not least, you want the furniture and decor of an interior to look as accurate as possible.

 

 

The colour rendering index (CRI) indicates how closely the colour of an object matches its appearance under the relevant light source (CRI100). The lower the CRI index, the poorer is the rendering of the surface colours of the illuminated objects. For living spaces, at least CRI80 is required. Depending on your needs, we can offer you luminaires with CRI>80, CRI>90 and CRI>95.

 

 

 

We have taken a closer look on the appearance of the coloured objects in our showroom, where Plain luminaire with featuring SunLike LEDs (co-developed by Seoul Semiconductor and Toshiba Materials) and with Tunable White feature is implemented. Measurements show:

  • CRI>97 
  • Checking the IES TM-30-18 Color Vector Graph (0-100; where 100 is reference light  source) ensures that your environment is filled with a perfect reproduction of colours in full colour spectrum. 
  • UGR<19
