NOTES
Lumen Maintenance Projections
Based on internal long-term reliability testing and stan-
dardized forecasting methods, Cree projects XLamp LEDs
to maintain an average of 70% lumen maintenance after
50,000 hours, provided the LED junction temperature is
maintained at or below 80°C.
Please read the XLamp Reliability application note for
more details on Cree’s lumen maintenance testing and
forecasting. Please read the XLamp Thermal Management
application note for details on how thermal design, ambi-
ent temperature, and drive current affect the LED junction
temperature.
Moisture Sensitivity
XLamp LEDs are shipped in sealed, moisture-barrier bags
(MBB) designed for long shelf life. If XLamp LEDs are
exposed to moist environments after opening the MBB
packaging but before soldering, damage to the LED may
occur during the soldering operation. The following derat-
ing table defines the maximum exposure time (in days)
for an XLamp LED in the listed humidity and temperature
conditions. LEDs with exposure time longer than the time
specified below must be baked according to the baking
conditions listed below.
Baking Conditions
It is not necessary to bake all XLamp LEDs. Only the LEDs
that meet all of the following criteria must be baked:

LEDs should be baked at 80ºC for 24 hours. LEDs may
be baked on the original reels. Remove LEDs from MBB
packaging before baking. Do not bake parts at tempera-
tures higher than 80ºC. This baking operation resets the
exposure time as defined in the Moisture Sensitivity sec-
tion above.
Storage Conditions
XLamp LEDs that have been removed from original MBB
packaging but not soldered yet should be stored in a room
or cabinet that will maintain an atmosphere of 25 ± 5ºC
and no greater than 10% RH (relative humidity). For LEDs
stored in these conditions, storage time does not add to
exposure time as defined in the Moisture Sensitivity sec-
tion above.
RoHS Compliance
The levels of environmentally sensitive, persistent biologi-
cally toxic (PBT), persistent organic pollutants (POP), or
otherwise restricted materials in this product are below
the maximum concentration values (also referred to as
the threshold limits) permitted for such substances, or
are used in an exempted application, in accordance with
EU Directive 2002/95/EC on the restriction of the use of
certain hazardous substances in electrical and electronic
equipment (RoHS), as amended through April 21, 2006.
Vision Advisory Claim
Users should be cautioned not to stare at the light of this
LED product. The bright light can damage the eye.
