CXA1820 LED
PRODUCT DESCRIPTION
The XLamp CXA1820 LED array
expands Cree’s family of high‑ux,
multi-die arrays, offering high
performance in an easy-to-use
platform. With XLamp lighting-class
reliability, the CXA1820’s uniform
emitting surface enables both
directional and non-directional
lighting applications and luminaire
designs. Available in 2-step and
4-step color consistency, and
featuring a 12-mm optical source,
the CXA1820 brings new levels of
ux and efcacy to this form factor.

OPERATING LIMITS
The maximum current rating of the CXA1820 is dependent on the case temperature (Tc) when the LED has reached
thermal equilibrium under steady-state operation. Please refer to the Mechanical Dimensions section on page 12 for
the location of the Tc measurement point.
