Notes for Table 6:

1. As measured at the position indicated in Figure 7.

2. Lumen maintenance is a projected average value based on constant current operation while respecting the specified maximum case

temperature. Observation of design limits included in this data sheet is required in order to achieve this projected Lumen Maintenance.

3. Lifetime shown is an estimation of expected lifetimes (Bxx, Lyy) computed as 90% lower confidence limit of the LUXEON Altilon product as

a function of drive current and case temperature. The lifetime estimates in the above table reflect statistical figures based on calculations of

technical data and are subject to change.
