XLamp^® XQ-A LED
Notes
Measurements
The luminous flux, radiant power, chromaticity and CRI measurements in this document are binning specifications only and solely
represent product measurements as of the date of shipment. These measurements will change over time based on a number of factors
that are not within Cree’s control and are not intended or provided as operational specifications for the products. Calculated values are
provided for informational purposes only and are not intended as specifications.
Pre‑Release Qualification Testing
Please read the LED Reliability Overview for details of the qualification process Cree applies to ensure long-term reliability for XLamp
LEDs and details of Cree’s pre-release qualification testing for XLamp LEDs. Cree did not perform Room Temperature Operating Life
(RTOL) testing on the XQ-A LED.
Lumen Maintenance
Cree now uses standardized IES LM-80-08 and TM-21-11 methods for collecting long-term data and extrapolating LED lumen maintenance.
For information on the specific LM-80 data sets available for this LED, refer to the public LM-80 results document.
Please read the Long-Term Lumen Maintenance application note for more details on Cree’s lumen maintenance testing and forecasting.
Please read the Thermal Management application note for details on how thermal design, ambient temperature, and drive current affect
the LED junction temperature.
Moisture Sensitivity
Cree recommends keeping XLamp LEDs in the provided, resealable moisture-barrier packaging (MBP) until immediately prior to soldering.
Unopened MBPs that contain XLamp LEDs do not need special storage for moisture sensitivity.
Once the MBP is opened, XLamp XQ-A LEDs may be stored as MSL 1 per JEDEC J-STD-033, meaning they have unlimited floor life in
conditions of ≤ 30 ºC/85% relative humidity (RH). Regardless of storage condition, Cree recommends sealing any unsoldered LEDs in the
original MBP.
RoHS Compliance
The levels of RoHS 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 2011/65/EC (RoHS2), as
implemented January 2, 2013. RoHS Declarations for this product can be obtained from your Cree representative or from the Product
Documentation sections of www.cree.com.
UL^® Recognized Component
Level 1 enclosure consideration. The LED package or a portion thereof has not been investigated as a fire enclosure or a fire and electrical
enclosure per ANSI/UL 8750.
