Dazor’s lighted magnifiers feature a lighting color and quality developed specifically to deliver the type of lighting needed for precision inspection processes.

Color and Color Quality of Light Defined

In artificial lighting, there are 3 terms to know that are fundamental to understanding differences in the color and color quality of light.  They are:

• Correlated Color Temperature (CCT): CCT correlates “color” to thermal temperature.  For example, a candle flame is yellow in color and emits a “soft” or “warm” light while a gas flame is hotter and emits a “blue white” light. Soft, warm light is great for creating a mood and making skin look smooth, but it is not ideal for lighting environments contrast is important – as in operating rooms or inspection areas.
  
  
• Kelvin (K): Kelvin is the actual thermal temperature scale that correlates to CCT correlates.
  
  
• Color Rendering Index (CRI): Color rendering index is a scale by which artificial light renders color the most accurately in relation to a known source – the sun.  Light produced from the sun covers all spectrum of visible light and has a CRI of 100. Generally speaking, the higher the CRI, the better.

Dazor vs. The Competition

The lighting used in Dazor magnifiers is specifically designed for quality control and inspection processes while leading competitors employ lighting designed for other applications.

Dazor - 6500K 95CRI

Dazor’s blue/white daylight, 6500K LEDs yield a CRI of 95 to achieve a light specific for inspection applications that require a high degree of visual discernment.   This lighting promotes alertness and allows defects to be identified more quickly and accurately.  In fact, quality control specialists use this lighting because it produces the best environment to create contrast, to see defects and perceive color the most precisely. 

Competitor A - 4100K 80CRI

Another leading magnifier manufacturer features lighting that is generally used in settings where flesh tones are most important.  The “red” colors create a warm and laid back atmosphere conducive to a spa, but not ideal for highlighting contrast and identifying defects.  Since this type of lighting tends to blend surface differences, it is not suited for quality control inspection environments

Competitor B - 5000K 80CRI

Another leading magnifier manufacturer uses a soft white light with yellow undertones, similar to outside lighting on a cloudy day.  It is a commonly available LED color often used in overhead office lights and commonly selected for its low cost and availability.  It is better choice than a 4100K color, but still misses the correct color temperature for quality control tasks requiring high contrast to identify defects quickly over prolonged inspection task times.
