Product information 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 Metal Halide lamps the quality and stability of the dose maintains the colour consistency. Hence the name 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. Single ended format Single ended Ceramic Metal Halide lamps are designed to provide symmetrical beam distribution using the axial configuration 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. Features • Consistent colour over life • Good colour uniformity lamp to lamp Applications areas • Bright light – in a very compact size • Excellent colour rendition • Improved reliability due to 3 part design • Up to 97 Lumens per Watt (LPW) efficacy • Up to 18,000 hours life • UV control • Colour temperatures 3000K, 4200K DATA SHEET Retail Office Hospitality Showbiz Commercial areas / city beautification / architectural Specification summary Description Wattage Colour Product Code Operating conditions Burning position Universal Luminaire characteristics Enclosed Notes: 1) Lamp voltage in the luminaire should not increase by more than 5V when compared to lamp voltage in free air. 2) Ballast protection required, according to IEC61167. Electrical characteristics * * The specification provides typical performance data for 70W operating from a 50Hz mains sinewave supply at rated power, and for 20w & 35w operating on typical electronic ballast. Actual values depend on ballast, supply voltage and application. 20W to be used only with an electronic ballast.

Standard Delivery 2-5 Days Over FREE (*Excluding items over 600mm in length) Next Day Delivery Available - £12.50 (Order By 2pm For Monday-Friday)
All in stock orders are dispatched on the day they are received if placed before 4pm.
Standard delivery we will use Royal mail, which is usually around 2-5 working days delivery
On a courier delivery, which we will often use for larger items, deliver can be expected between 2 and 5 days from the point of order. If for any reason you order is set to take longer than this, we will contact you to keep you informed.
The website will quote as close to the shipping price as we can, however in some circumstances, with some of the more remote areas of the UK, we will contact you and quote you a price once the order has been received
We can also deliver into Europe and the rest of the world, but price is dependent on weight and dimensions. Price is variable and is given upon checkout. Often we will quote as close to the price as we can, however in some circumstances, with shipping outside of the UK, we will contact you and quote you a price once the order has been received.
For next day delivery (at an additional charge), your order must be placed by 2pm Monday to Friday. Next day delivery does not include weekend delivery, and as such all orders placed next day on a Friday will be delivered the following Monday, or if after 2pm will be delivered on Tuesday
