ProDuCt DEsCriPtion

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

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 CXB1820 LeD

successfully in luminaire designs.
