High-pressure discharge lamps (also known as high-intensity discharge (HID) lamps) differ from incandescent lamps in the way in which they produce light. They are very efficient because they generate extremely high luminous flux in a very small space. For example, a 2000 W metal halide lamp, such as the ones installed in foot- ball stadium floodlights, produces as much light as two 5000 W incandescent lamps. The area in which the light is produced is no larger than a 2 euro coin. Other advantages of modern high-pres- sure discharge lamps include low ther- mal output, excellent colour rendering and long life. What’s more, because of the compact dimensions of these lamps, their light can be easily and accurately directed. Consequently, high-pressure discharge lamps are the light sources of choice • wherever products and objects need to be presented, such as in shop windows and retail outlets • where bright light and long life are important, for example in factories, in stadiums and for street lighting • and for plant lighting.
The document presents Osram’s POWERBALL and POWERSTAR high‑pressure discharge lamp families, focusing on the POWERBALL HCI‑T series. It describes the lamps’ high luminous efficacy, compact size, UV‑reduced design and suitability for enclosed luminaires. Technical data, wiring diagrams and operating instructions are provided for each model.
Applications include retail shop windows, museums, art galleries, interior and exterior architectural lighting, as well as industrial and street lighting. The guide also covers system guarantees, recommended control gear and end‑of‑life replacement criteria.
