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.

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 XM-L2 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 the 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
