PRODUCT DESCRIPTION
The XLamp® CXB3050 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
CXB3050 LED delivers high lumen output
and high efficacy in a single, easy‑to‑use
package that eliminates the need for reflow
soldering.
The CX Family LED Design Guide provides
basic information on the requirements
to use the CXB3050 LED successfully in
luminaire designs.
