Important Notes:  
1. All ranks will be included per delivery; rank ratio will be based on the dice distribution.  
2. Tolerance of measurement of luminous intensity is ±10%.  
3. Tolerance of measurement of the color coordinates is ±0.01.  
4. Tolerance of measurement of VF is ±0.05 V.  
5. Packaging methods are available for selection; please refer to the “Cree LED Lamp Packaging” document.  
6. Please refer to the “Cree LED Lamp Reliability Test Parameters” document for reliability test conditions.  
7. Please refer to the “Cree LED Lamp Soldering & Handling” document for information about how to use this LED  
product safely.  
8. Do not handle the device by the SMD surface. Care must be taken to avoid damage to the SMD surface or the  
interior of the device, which can be damaged by excessive force to the SMD surface.
