Bin codes are used to sort LEDs by luminous flux (lumen output at a specified drive level), color, tint, and Vf. For example, a U-bin Lux III will have more output than a T-bin Lux III at a set drive level. Commonly desirable flux bins (at the time of writing) are:
-Lux I: R or S
-Lux III: T or U
-Lux V: W or X
-XR-E: Q2 through R2
-SSC P4: U or V
-Rebel: 0080 or 0100
