CXA2 LeD Arrays lead the
industry in efficacy and reliability for
ceramic‑based COB LEDs. Cree CXA2
LeDs easily deliver TM-21 lifetimes
well beyond L90 60,000 hours under
a wide range of operating conditions.
CXA2 LeD Arrays share the same
physical design as XLamp CXA and
CMA LED families, allowing lighting
manufacturers to leverage the existing
optical,
mechanical
and
electrical
design elements to accelerate time to
market without additional cost.

CXB1816 LED
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 16 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 17 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.
