Osram Sylvania Unveils New Safety Feature for HMI Metal Halide Lamps

At Cine Gear Expo 2014 held earlier this month in Hollywood, California, Osram Sylvania introduced a new group of single-end HMI metal halide lamps that incorporate a doped UV-Stop (UVS) quartz outer jacket which reduces UVB and UVC emissions up to 99.9%. UVS not only extends the life of fixture components, it also reduces UV emissions from the back of fixtures. Most importantly, HMI lamps equipped with UVS achieve these benefits without compromising performance. New single-end OSRAM HMI UVS lamps will come with an orange base and are available in 200W, 400W, 575W, 800W, 1,200W, 1,600W, and 1,800W versions, delivering 16,000 to 165,000 lumens with an average rated life up to 1,000 hours.

"For over 40 years, OSRAM HMI lamps continue to provide the film and event industries with high intensity light that closely simulates natural sunlight," said Stephen Robertson, product marketing manager, Osram Sylvania. "Now, we are offering the same high performance lamps with a new safety feature that greatly reduces the risk of exposure to ultraviolet radiation."

Invented by Osram in 1967, HMI lamps remain the standard light source for the film and television industry because they simulate daylight color temperature conditions of 6,000K and have excellent color rendering (90+) with photometric integrity throughout their life. In fact, Osram received an Oscar in 1987 and a Primetime Emmy Engineering award in 2007 for the invention and continuous improvement of HMI lamp technology.

Highly efficient HMI lamps have a high luminous efficacy of nearly 100 lumens per watt (LPW) and are available in single or double end with wattages ranging from 200 to 24,000. Dimmable, with a hot restart capacity, OSRAM HMI lamps are over five times more efficient than incandescent light. Applications include exhibition lighting; film, TV and video productions; industrial solar simulation; lighting for major events; professional photography; and stage lighting such as theatre and opera.
