Скачать или смотреть HPS lamp in metal halide fixture

Who says that in the US that you cannot run HPS bulbs in metal halide fixtures? In this video, you can see that a European Osram NAV-T Super 4Y 70w HPS lamp is being used on a US M98 metal halide ballast since these lamps are electrically interchangeable with our 70w pulse start metal halide lamps and NOT interchangeable with our 70w HPS lamps. In addition, all other European HPS lamps from 35w to 150w are electrically interchangeable with our pulse start metal halide lamps from 35w to 150w. If you use this exact lamp on our 70w S62 HPS ballasts, it will cycle due to the fact that this lamp requires a higher arc voltage that a standard 70w S62 HPS lamp. However, using 70w S62 HPS lamps in 70w M98 metal halide fixtures will overheat the ballast. Note the 60hz hum that comes from the ballast.
