Cree® XLamp® CXB1512 LED
PRODUCT DESCRIPTION
The XLamp® CXB1512 LED Array is a
member of the second generation of
the CXA family that delivers up to 30%
higher efcacy and up to 20% higher
lumens than the rst 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 and 2-step and
3-step Premium Color bins, the CXB1512
LED delivers high lumen output and high
efcacy in a single, easy‑to‑use package
that eliminates the need for reow
soldering.
The CX Family LED Design Guide
provides basic information on the
requirements to use the CXB1512 LED
successfully in luminaire designs.
