Notes for Table 8:
1. LUXEON V Portable is designed primarily for portable lighting and other applications requiring operating lifetimes of
500 hours and less. While the device will operate past 500 hours, its lumen maintenance cannot yet be characterized.
Longer life versions of white LUXEON V will become available in the future.
2. Average lumen maintenance is dependant on heat sink temperature. A recoverable light output loss may occur during
the first 500 hours of operation.
3. For additional information please consult your Philips Lumileds Authorized Distributor or Philips Lumileds sales
representative.
