XR-E and XR-C LED
Binning and Labeling
Introduction
This document describes the product nomenclature required to select and order
Cree’s XLamp XR-E and XR-C LEDs. XLamp XR-E and XR-C LEDs are tested and
sorted into bins which are then combined into orderable kits identied by an order
code.
All XLamp LEDs are tested and sorted by color and brightness into a unique bin.
Each bin contains LEDs from only one color and brightness group and is uniquely
identied by a bin code. White XLamp LEDs are sorted by chromaticity (color) and luminous ux (brightness). Color
XLamp LEDs are sorted by dominant wavelength (color) and luminous ux (brightness), or in the case of royal blue,
radiant ux (brightness). Amber, red-orange and red LEDs are additionally binned into forward voltage bins. LEDs
are shipped on reels containing LEDs from one bin and are always labeled with the appropriate bin code.
Kits contain LEDs from a number of similar bins and are fully dened by their order codes. A full explanation of the
order codes for each family, as well as a list of standard order codes, is provided in this document.
