When combined with thehalide doses used in Arcstream\u2122 Metal Halide lamps thenthe quality and stability of the dose maintains the colourconsistency. Hence the name ConstantColor\u2122 CMH.Metal halide lamps, traditionally made with quartz arc tubes,are prone to colour shift through life and lamp-to-lampcolour variation. Some of the dose, e.g. sodium, (an importantcomponent of metal halide lamps), can migrate throughquartz to cause colour shift and loss of light through life.The ceramic arc tube resists this material loss, can bemanufactured to tighter tolerances and withstands a highertemperature to provide a more constant colour.Features\u2022 Consistent colour over life\u2022 Colour uniformity lamp to lamp\u2022 Excellent colour rendition (CRI: 80+)\u2022 Up to 24% higher efficacy than Quartz Metal Halide\u2022 Up to 24,000 hours life\u2022 UV control\u2022 Easy retrofit for High Pressure Sodium and High PressureMercury lamps Elliptical and tubular formatsConventional lamp shapes with a screw-type base enablesexisting luminaire designs to use ConstantColor\u2122 CMH lampswith little or no modification to the optical system.Coated and clear versions enable close matching to the lamptypes previously used. Applications areas\u2022 Architectural floodlighting\u2022 Street Lighting\u2022 City Beautification\u2022 Stage\/Studio \u00a0 \u00a0 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. \u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"
