CXA1816 LED
ProDuCt DEsCriPtion
The
XLamp
®
CXA1816
LeD
array
expands Cree’s family of high‑flux,
multi‑die arrays in a smaller, easy‑to‑use
platform. With XLamp LED lighting‑class
reliability,
the
CXA1816’s
small,
uniform emitting surface enables both
directional and non‑directional lighting
applications including lamp retrofit and
luminaire designs. Available in 2‑step,
3‑step and 4‑step color consistency,
and featuring a 12‑mm optical source,
the CXA1816 brings new levels of flux
and efficacy to this form factor.
The
CX Family LED Design Guide
provides basic information on the
requirements to use the CXA1816 LED
successfully in luminaire designs.

oPErAting LiMits
The maximum current rating of the CXA1816 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.

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 16).
•
Cree XLamp CXA1304 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.
