Thermal Design
The maximum forward current is determined by the thermal resistance between the LED 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.

Notes
Moisture Sensitivity
In testing, Cree has found XLamp MX-3 LEDs to have unlimited oor life in conditions ≤30ºC / 85% relative humidity
(RH). Moisture testing included a 168 hour soak at 85ºC / 85% RH followed by 3 reow cycles, with visual and electrical
inspections at each stage.
RoHS Compliance
The levels of environmentally sensitive, persistent biologically toxic (PBT), persistent organic pollutants (POP), or other-
wise 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.
