Therefore | A particular design of LED will usually be sold in a number of different bins. Although LED production is tightly controlled, the resulting LEDs have slightly varying properties. Therefore LEDs are sorted into bins based on flux (output) and tint. As production is refined, higher bins may become available. Thus the Cree XR-E Q5 was introduced a year or two after the earlier, less bright XR-E P4. | ||
The [[Brightness Bins]] article summarizes light output data (lumens) for bins of various LED's. | The [[Brightness Bins]] article summarizes light output data (lumens) for bins of various LED's. | ||
LEDs are also binned by the resulting tint of the LED. See pages for each LED manufacturer for a chromaticity chart showing tint bins. Some companies base their tint bins on [[ANSI White]] standards. | |||
Some LED's are also binned by [[Terminology#Vf|Vf]], or forward voltage. | Some LED's are also binned by [[Terminology#Vf|Vf]], or forward voltage. | ||
