PRoDuCt DEsCRiPtion

builds on the breakthrough performance

of the original MK-R by enabling

high-voltage driver solutions while

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

halogenlamps.MK-R2LeDsareoptimized

for use in track, accent, lamp retrofit,

downlighting and other applications

where color quality, consistency and

optical control are required.
