HMI lamps simulate a daylight colour temperature of 6000K and have excellent colour rendering and photometric integrity throughout their life.<\/p>\n<p>OSRAM received an OSCAR\u00ae in 1987 and a PRIMETIME EMMY\u00ae Engineering award in 2007 for the invention and continuous improvement of HMI lamp technology. As a result, the HMI lamp family continues to be an integral part of film sets around the world.<\/p>\n<p>However, another one of the major applications of OSRAM HMI\u00ae 4000 W\/DXS is in solar simulation, specifically in automotive testing laboratories. Solar radiation causes numerous unwanted effects on materials exposed for extended periods. These changes range from aesthetics (like fading colours) to structural changes (increase in brittleness and the loss of various strengths).<\/p>\n<p>Solar simulation testing is used to simulate the spectra of natural sunlight to help determine how a material will react when exposed to sunlight over a period of time. A solar simulator is also known as an artificial sun as it is a device that provides illumination which is as close to the natural light as possible.<\/p>\n<p>The purpose of the solar simulator is to provide a controllable indoor test facility under laboratory conditions, used for the testing of solar cells, sunscreen, plastics, and other materials and devices.<\/p>\n<p>The OSRAM HMI\u00ae 4000 W\/DXS SOLAR is a double-ended metal halide lamp. Its funnel-shaped burner is specially designed for super quiet operation on electronic power supplies which acts as a major support base when we talk about solar Simulation.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-455\" src=\"https:\/\/osramnlighting.com\/wp-content\/uploads\/2021\/04\/Latest-1.jpg\" alt=\"osram solar simulator\" width=\"476\" height=\"206\" srcset=\"https:\/\/osramnlighting.com\/wp-content\/uploads\/2021\/04\/Latest-1.jpg 476w, https:\/\/osramnlighting.com\/wp-content\/uploads\/2021\/04\/Latest-1-300x130.jpg 300w\" sizes=\"(max-width: 476px) 100vw, 476px\" \/><\/p>\n<p>The HMI\u00ae 4000 W\/DXS SOLAR can be operated either on magnetic ballast (CCG) or on electronic power supplies (ECG). For best performance, we recommend the use of an ECG. Magnetic ballasts can reduce lamp performance and hence, caution is of the best priority in these cases especially when it concerns the Automotive Testing Laboratory or a car manufacturing factory.<\/p>\n<ul>\n<li>Lamp wattage: 4000 W<\/li>\n<li>Nominal voltage: 204 V<\/li>\n<li>Lamp voltage: 200 V<\/li>\n<li>Nominal current: 23.5 A<\/li>\n<li>Lamp current: 24.0 A<\/li>\n<li>Colour temperature: 6000 K<\/li>\n<li>CRI \u203a 90<\/li>\n<li>Lifespan: 500 h<\/li>\n<li>Base (standard designation): SFa21-12<\/li>\n<\/ul>\n<p>Luminous flux, CRI and CCT may vary during lifetime.

The functionality of the individual features of our products is influenced by various external factors and may therefore differ depending on the individual application or condition of use.<\/p>\n<p>It is up to the user to make his own determination as to the suitability of a lamp for his intended application or use and to assume responsibility for that determination.<\/p>\n<p>Boosting of metal halide lamps: Operating the lamp at higher than the rated lamp wattage is not allowed. Besides affecting the photometric properties of the lamp (higher CRI, lower CCT) the increased load on the electrode system, sealing and the bulb will lead to a premature failure of the lamp while being used in an automotive Testing Laboratory or even a car manufacturing factory which can result in hazardous problems.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-456\" src=\"https:\/\/osramnlighting.com\/wp-content\/uploads\/2021\/04\/osram-solar-simulation-effect.jpg\" alt=\"osram solar simulation effect\" width=\"629\" height=\"194\" srcset=\"https:\/\/osramnlighting.com\/wp-content\/uploads\/2021\/04\/osram-solar-simulation-effect.jpg 629w, https:\/\/osramnlighting.com\/wp-content\/uploads\/2021\/04\/osram-solar-simulation-effect-300x93.jpg 300w\" sizes=\"(max-width: 629px) 100vw, 629px\" \/><\/p>\n<h2><strong><u>Light output:<\/u><\/strong><\/h2>\n<p>Test conditions: 4000W operation &gt; 6 min for lamp output stabilization<\/p>\n<p>Lamp driver:May&amp;Christe HMI 4000W-05,2H<\/p>\n<p>Luminous flux: Light output of the lamp is measured within an integrating sphere (diameter 2000 mm).<\/p>\n<ol>\n<li>I) Initial values<\/li>\n<\/ol>\n<p>Min.: 330.000 lm<\/p>\n<p>Typical: 398.000 lm<\/p>\n<ol>\n<li>II) After average service life (500 h)<\/li>\n<\/ol>\n<p>Min.: 50% of the initial value (B50)<\/p>\n<p>Color coordinates: I) Initial values<\/p>\n<p>Typical x: 0,308<\/p>\n<p>Typical y: 0,313<\/p>\n<p>CRI:I) Initial values<\/p>\n<p>Ra typical &gt; 90<\/p>\n<p>Correlated Color Temperature2 I) Initial values<\/p>\n<p>Typical: 7000 (+400 \/ -400) K<\/p>\n<p>Luminous flux, CRI and CCT may vary during lifetime.
