CXB1816 LED
ProDuCt DEsCriPtion
The XLamp
®
CXB1816 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 3-step
Premium Color bins,, the CXB1816
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 CXB1816 LeD
WWW.CREE.Com/XLAmp
successfully in luminaire designs.

oPErating LiMits
The maximum current rating of the CXB1816 depends on the case temperature (Tc) when the LED has reached thermal equilibrium under
steady-state operation. The graph shown below assumes that the system design employs good thermal management (thermal interface
material and heat sink) and may vary when poor thermal management is employed. Please refer to the Mechanical Dimensions section
on page 14 for the location of the Tc measurement point.
Another important factor in good thermal management is the temperature of the Light Emitting Surface (LES). Cree recommends a
maximum LES temperature of 135 °C to ensure optimal LED lifetime. Please refer to the Thermal Design section on page 15 for more
information on LeS temperature measurement.

Notes
•
Cree maintains a tolerance of ±7% on flux and power measurements, ±0.005 on chromaticity (CCx, CCy) measurements and a tolerance of ±2 on CRI
measurements. See the Measurements section (page 21).
•
Cree XLamp CXB1816 LED order codes specify only a minimum flux bin and not a maximum. Cree may ship reels in flux bins higher than the minimum
specified by the order code without advance notice. Shipments will always adhere to the chromaticity bin restrictions specified by the order code.
*
For 80 CRI minimum LEDs, CRI R9 minimum is 0 with a ±2 tolerance. For 90 CRI minimum LEDs, CRI R9 typical is 60.
** Flux values @ 25 °C are calculated and for reference only.
