What is CRI:

Color Rendering Index, it describes how a light source makes the color of an object appear to human eyes,and how well subtle variations in color shades are revealed. The CRI is a scale from 0 to 100 percent indicating how accurate a "given" light source is at rendering color when compared to a "reference" light source.

The higher the CRI, the better the color rendering ability. Light sources with a CRI of 80 to 90 are considered good at color rendering. Light sources with a CRI of 90 or higher are excellent at color rendering and should be used for tasks requiring the most accurate color discrimination.

Product Parameters of 100W COB LED:

Brand of LED Chip: CITIZEN

Color Temperature: 5600K

Voltage (V): 36-38Volts

Rated Current (A): 2.5A, Max 2.7A, please note: in order to protect COB LED not burned, the working current must be limited to 2.8A, can not over 2.8A, hope you understand.

Luminous Flux (LM): 9500-10000 LM

CRI Ra: 93-96

Material: Copper Brackets

Working Temperature: -30-60℃

Note: It will work more than 30000 hours if the working temperature is less than 60 Degree Celsius. So, they need to work wih heat sinks or Thermal Silica otherwise the light will die due to too much heat. Please see this our testing Video at listing page.

The cost performance of our this 100W 5600K COB LED is better than YUJI COB LED.
