NOTES

Measurements

The luminous ux, radiant power, chromaticity and CRI measurements in this document are binning specications

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

specications for the products. Calculated values are provided for informational purposes only and are not intended as

specications.

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 specic 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 XB-D LEDs may be stored as MSL 1 per JEDEC J-STD-033, meaning they have unlimited

oor 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.

REACh Compliance

REACh substances of high concern (SVHCs) information is available for this product. Since the European Chemical

Agency (ECHA) has published notice of their intent to frequently revise the SVHC listing for the foreseeable future,

please contact a Cree representative to insure you get the most up-to-date REACh SVHC Declaration. REACh banned

substance information (REACh Article 67) is also available upon request.

UL Recognized Component

Level 4 enclosure consideration. The LED package or a portion thereof has been investigated as a re and electrical

enclosure per ANSI/UL 8750.
