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 and 2‑step and 3‑step Premium Color 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. The CX Family LED Design Guide provides basic information on the requirements to use the CXB1820 LED successfully in luminaire designs.
