Cree’s XLamp
®
High-Current LeD Array
family is optimized for best-in-class
lumen output, efficacy and reliability at
high drive currents. XLamp CMA LeDs
share the same package design and
LeS sizes as Cree’s industry-leading
CXA2 Standard Density LeDs, enabling
lighting manufacturers to address a
range of performance requirements for
applications such as track, downlight
and outdoor lighting using a single
easy-to-use platform.

available in two different versions:
Standard and eTone LeDs.
The eTone version delivers beautiful 90
CRI light quality at the same efficacy
as today’s standard 80 CRI LeDs.
Featuring the same mechanical and
optical characteristics as the Standard
version, the eTone LeDs allow easy
upgrades from 80 CRI to 90 CRI without
sacrificing performance.

The maximum current rating of the CMA1840 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. either solder pad shown in the Mechanical
Dimensions section on page 3 can be used as 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 140 °C to ensure optimal LED lifetime. Please refer to the Thermal Design section on page 3 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 20).
•
For 80 CRI minimum LeDs, CRI R9 minimum is 0 with a ±2 tolerance. For 90 CRI minimum LeDs, CRI R9 typical is 60.
