ConstantColor™ CMH™
Ceramic Metal Halide Lamps
Single Ended G8.5
Product Information
Lamp technology
ConstantColor CMH™ lamps combine HPS technology
(providing stability, efficiency & uniformity) and 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.
Features
• Consistent colour over life
• Good colour uniformity lamp to lamp
• Bright light – in a very compact size
• Excellent colour rendition
• Improved reliability due to 3 part design
• Up to 97 Lumen per Watt (LPW) efcacy
• Up to 15,000 Hr life
• UV control
• Colour temperatures 3000K, 4200K
Single ended format
Single ended Ceramic Metal Halide lamps are designed to
provide symmetrical beam distribution using the axial con-
figuration of the discharge arc.
A variety of beam angles are possible and adjustable beam
control can be built into the luminaire.
This compact lamp shape enables luminaire size to be
minimised and the bi-pin lamp base enables easy changing
with front access.
Applications areas
• Retail
• Ofces
• Stage/Studio
• Architectural lighting
• Display Cabinet
• Hotels
