| The
Basics |
|
Ceramic
Metal Halide (CMH) is a new
breed of metal halide lamps that
uses a ceramic arc tube instead
of the traditional quartz arc
tube. Ceramic can tolerate a
much higher temperature than
quartz which results in improved
color rendering and Kelvin temperature |
|
CMH
can provide the concentrated
beams required in architectural
spaces, as opposed to the traditional
“broadcast” beam. |
|
Against
HIR PAR’s, CMH uses ½ the energy,
can last 3-4 times longer and
can use less fixtures in a space
(higher lpw). |
|
Against
standard metal halide, CMH can
deliver up to 20% more output,
very low lumen depreciation,
CRI up to 90 or better and up
to 95 lpw efficiency. Also, color
uniformity is consistent over
time. Ballasts are electronic. |
|
Lamp
wattages range from 20 to 400
watts. Lamp life is extraordinary,
up to 15,000 hours in certain
configurations. |
