Notes for Table 5:
1. Lumileds maintains a tester tolerance of ±0.005 on x,y coordinates.
2. Major and minor axis (a,b) from table 5 are a reference as depicted in gure 7.
3. 3-step for all 80 and 90CRI part numbers.
4. 5-step for all 70CRI part numbers.
5. Please contact Lumileds for requests outside 3-step for 80 and 90CRI parts.
