The color homogeneity of white leds is a problem for manufacturing companies of white leds. Because of the way the phosphorous is distributed in the led the white led light shows change in light tone when viewed from angles.

It is the binning process white making white leds which accounts for whether the white led will have more color homogenous light. Osram Opt has constructed 120 bins which will allow for more color homogeneity of light in white led with colour coordinates precisely defined. The different leds in a single white group emit the same white light bringing colour homogeneity of white
