Knowledge Color Rendering Index (CRI): What Do Ra and R9 Mean?
The color rendering index (CRI) is a quantitative measurement of a white light source’s ability to reproduce the colors of various objects faithfully in comparison to a reference light source of the same correlated color temperature (CCT). The reference light source is a Planckian radiator (for...- Shine

Knowledge What Causes Color Shifts in LED Lights?
Color stability refers to the ability of light sources to maintain their spectral power distribution (SPD) over time. While lumen maintenance is important for LED packages, the change in chromaticity—typically referred to as color shift—must not be overlooked. The term chromaticity refers to the...- Shine

Knowledge What Is LED Binning?
LED binning is a process of sorting LEDs according to specific criteria such as chromaticity, lumen output (luminous flux), and sometimes forward voltage (amount of voltage it takes to turn on an LED). Variability in the manufacturing process from wafer production and crystal growth to component...- Shine

Knowledge How Stokes Shift Impacts LED Efficiency and Color Quality?
Phosphor conversion (PC) is the most widely used approach for generating white light with LEDs. The technique involves using a blue LED (InGaN chip) to pump light into a phosphor down-converter. A portion of short-wavelength photons is absorbed by phosphors and converted into longer wavelength...- Splendor
