Cree^® XLamp^® CXB1820 LED
Product family data sheet
Product Description
The XLamp^® CXB1820 LED Array is a
member of the second generation of
the CXA family that delivers up to 30%
higher efficacy and up to 20% higher
lumens than the first generation in the
same LES. The higher performance
second generation CXA LED Arrays
provide a drop-in performance upgrade
to existing CXA LED designs to shorten
product development time. In addition,
the CXB LEDs also allow lighting
manufacturers to achieve the same
or better performance with a smaller
LES, enabling a smaller, more impactful
luminaire. Available in 2‑step, 3‑step and
5‑step EasyWhite^® bins, the CXB1820
LED delivers high lumen output and
high efficacy in a single, easy‑to‑use
package that eliminates the need for
reflow soldering.
