Product descriPtion

The

XLamp

MK-R2

easyWhite

LeD 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 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.
