Thermal esign The maximum forward current is determined by the thermal resistance between the LE junction and ambient. It is crucial for the end product to be designed in a manner that minimizes the thermal resistance from the solder point to ambient in order to optimize lamp life and optical characteristics. 00 000 Maximum urrent (m) 00 000 00 Thermal esign 000 00 Rj-a = /W Rj-a = 7 /W Rj-a = 0 /W Rj-a = /W 0 0 0 0 60 80 00 0 0 mbient Temperature (º) Relative Flux vs. urrent (T J = ) Relative Luminous Flux (%) 0% % 00% 7% 0% % 00% 7% 0% % 00% 7% 0% % 0% 0 00 00 600 800 000 00 00 600 800 000 00 00 600 800 000 Forward urrent (m) opyright 00-0 ree, Inc. ree, ll Inc. rights ll reserved. rights reserved.

Notes Lumen Maintenance Projections ree now uses standardized IES LM-80-08 and TM-- methods for collecting long-term data and extrapolating LE lumen maintenance. For information on the specific LM-80 data sets available for this LE, refer to the public LM-80 results document at www.cree.com/xlamp_app_notes/lm80_results. Please read the XLamp Long-Term Lumen Maintenance application note at www.cree.com/xlamp_app_notes/lumen_ maintenance for more details on ree s lumen maintenance testing and forecasting. Please read the XLamp Thermal Management application note at www.cree.com/xlamp_app_notes/thermal_management for details on how thermal design, ambient temperature, and drive current affect the LE junction temperature. Moisture Sensitivity In testing, ree has found XLamp XM-L LEs to have unlimited floor life in conditions 0 º/8% relative humidity (RH). Moisture testing included a 68-hour soak at 8 º/8% RH followed by reflow cycles, with visual and electrical inspections at each stage. ree recommends keeping XLamp LEs in their sealed moisture-barrier packaging until immediately prior to use. ree also recommends returning any unused LES to the resealable moisture-barrier bag and closing the bag immediately after use. RoHS ompliance 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 irective 0/6/E (RoHS), as amended through June 8, 0. RoHS eclarations for this product can be obtain from your ree representative or obtained from the Product Ecology section of www.cree.com. REh ompliance REh substances of high concern (SVHs) information is available for this product. Since the European hemical gency (EH) has published notices of their intent to frequently revise the SVH listing for the foreseeable future, please contact a ree representative to insure you get the most up-to-date REh eclaration. Historical REh banned substance information (substances restricted or banned in the EU prior to 00) is also available upon request. UL Recognized omponent Level enclosure consideration. The LE package or a portion thereof has been investigated as a fire and electrical enclosure per NSI/UL 870. Vision dvisory laim WRNING: o not look at exposed lamp in operation.
