providing a small, uniform, single point
source for precise optical control. The
MK-R2 shares the same mechanical
footprint as the original MK-R, providing
customers with a seamless upgrade path
and shortening the LeD luminaire and
retrofit lamp design cycle.
MK-R2 LeDs are designed for high-output,
directional
lighting
applications
and
are the ideal replacement for lighting
applications that currently use inefficient
halogen lamps. MK-R2 LeDs are optimized
for use in track, accent, lamp retrofit,
downlighting and other applications
where color quality, consistency and
optical control are required.

Notes:
• Cree maintains a tolerance of ±7% on flux and power measurements, ±0.005 on chromaticity (CCx, CCy) measurements and ±2 on CRI
measurements. See the Measurements section (page 10).
•
Minimum CRI for 80-CRI White is 80.
