The Feasa LED Analyzer is an instrument that tests the HSI (Hue, Saturation, Intensity), RGB (Red, Green, Blue Color content of a single LED), xy Chromaticity, Dominant Wavelength and cct Color temperature of Light Emitting Diodes (LEDs) in a test process.
Most LED manufacturers will specify their White LED's using Chromaticity co-ordinates x-y. This is a two-dimensional Chart with x on the horizontal axis and y on the vertical axis. The range of x and y lies between 0 and 1.
