Cree closely controls the distribution of our LM-80 data files as there is concern that the files could end up in the public domain. We only provide our LM-80 data to those customers using our product in their luminaires and are seeking Energy Star approval.
Further information on Cree’s LM-80 testing methodology can be found in the recently published Lumen Maintenance Application Note.
In addition, Cree’s lighting-class XLamp XP LEDs became UL-recognized on August 4, 2009 (registration file OOQA2.E326295). Due to the glass lens, Cree’s XLamp XR family and MC-E LEDs are considered enclosures by UL and do not require registration.
