Color Rendering Index and Lumens Are Important for Ring LED Chandelier

Whether we are purchasing ring led chandelier in a offline store or online, we must first understand several important knowledge points about ring led chandelier, such as color temperature,beam angle,light efficiency, color rendering index and lumens. Today we are focus on the color rendering index and lumens.

Generally,CRI is the abbreviation of color rendering index. Color rendering index can be regarded as a necessary measurement standard to detect color rendering quality. In other words,the higher the color rendering index value, the better the color rendering index for ring led chandelier or other type of indoor commercial LED lights.

The maximum value of the color rendering index is 100, the color rendering index of the led lighting fixtures more closer it is to this value, the more realistic the color displayed by the lamp is.but the minimum value may also be a negative number. For example, the yellow light color rendering index of a sodium vapor lamp is negative 44.

If consumers require a higher color rendering index, such as 90, 95 or 97,we can also customize it for them. Our ring led chandeliers are available in standards three different sizes and can customized. In addition to the ordinary white casing, black casings can also be produced, and all have dimming functions for consumers to choose.

Another important characteristic of LED lamps is lumens. What are lumens? Generally speaking, lumens can be considered as the brightness or output indicator of various LED commercial lighting (including ring led chandelier), for example, if the total light output of the ring led chandelier is 4000lm, it means that the lumens of this ring led chandelier is 4000.

As for the ring led chandelier,as we mentioned before,it is available in three specifications: 350mm,400mm and 600mm, and the actual light efficiency depends on the specifications. For example, for the ring led chandelier with 400mm size and 4000K color temperature, its maximum The light efficiency can reach 100lm/W, and the total lumen is 3000lm. For 600mm size, 4000K color temperature and dimming function, the light efficiency is about 120lm/W and the total lumen value is 4800lm. The warranty period of all sizes of ring led chandelier is three years, which is Your best affordable choice!
