Additional Information

Product information
ConstantColor™ CMH lamps combine the HPS technology
(providing stability, efficiency & uniformity) and the Metal
Halide Technology (providing bright white quality light)
to produce highly efficient light sources with good colour
rendering and consistent colour performance through life.
This is achieved by using the ceramic arc tube material from
the Lucalox™ lamp, which minimises the chemical changes
inside the lamp through life. When combined with the
halide doses used in Arcstream™ Metal Halide lamps then
the quality and stability of the dose maintains the colour
consistency. Hence the name ConstantColor™ CMH.
Metal halide lamps, traditionally made with quartz arc tubes,
are prone to colour shift through life and lamp-to-lamp
colour variation. Some of the dose, e.g. sodium, (an important
component of metal halide lamps), can migrate through
quartz to cause colour shift and loss of light through life.
The ceramic arc tube resists this material loss, can be
manufactured to tighter tolerances and withstands a higher
temperature to provide a more constant colour.
• Consistent colour over life
• Colour uniformity lamp to lamp
• Excellent colour rendition (CRI: 80+)
• Up to 24% higher efficacy than Quartz Metal Halide
• Up to 24,000 hours life
• UV control
• Easy retrofit for High Pressure Sodium and High Pressure
Mercury lamps

Elliptical and tubular formats
Conventional lamp shapes with a screw-type base enables
existing luminaire designs to use ConstantColor™ CMH lamps
with little or no modification to the optical system.
Coated and clear versions enable close matching to the lamp
types previously used.

Applications areas
• Architectural floodlighting
• Street Lighting
• City Beautification
• Stage/Studio



R Warning:

This lamp can cause serious skin burn and eye inflammation from shortwave ultraviolet radiation
if outer envelope of the lamp is broken or punctured, and the arc tube continues to operate.
Do not use where people will remain for more than a few minutes unless adequate shielding
or other safety precautions are used. Certain types of lamps that will automatically
extinguish when the outer envelope is broken or punctured are commercially available.
