Product descriPtion
The
XLamp
CXA1850
expands
Cree’s family of High Density (HD)
LeD arrays, featuring a 12-mm
optical source and enabling lighting
manufacturers to create a new
generation of products that delivers
the same intensity and light quality
as
70-W
ceramic
metal
halide
(CmH) at up to 50 percent lower
power. The new HD class of CXA
arrays
provide
unrivaled
lumen
density that can reduce system
cost for the next generation of LeD
spotlights.
The
CXA
LeD

Refer to the operating Limits section.
oPerating limits
The maximum current rating of the CXA1850 is dependent on the case temperature (Tc) when the LeD has reached
thermal equilibrium under steady-state operation. please refer to the mechanical Dimensions section on page 16 for
the location of the Tc measurement point.

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.
* Flux values @ 25 °C are calculated and for reference only.
