The cost performance of our this 100W 5600K COB LED is better than YUJI COB LED. YUJI COB is too expensive
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 :
1: Brand of LED Chip: CITIZEN
2:CRI Ra: 95+
3: Color Temperature: 5400K-5700K(our customer testing report, 5600K, as below pictures)
4: Voltage (V): 36-38Volts
5: 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.
6: Luminous Flux (LM): 9500-10000 LM
7: Material: Copper Brackets
8: 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 heatsinks and Thermal Silica for cooling and heat dissipation, otherwise the COB will be burn broken due to too much hot.
