For film, TV and still photography, OSRAM metal halide HMI lamps are the professional’s choice for exterior and interior daylight lighting. Thanks to the special blend of mercury and metal halide in the arc tube, HMI lamps generate the 6000K color temperature required to match natural daylight, making them very effective for stage lighting and large screen projection applications. Advanced Gap Shortened technology in some models results in higher arc brilliance for improved fixture efficiency. Single-ended HMI lamps offer an extremely compact package and long service life. HMI lamps also offer extremely high luminous efficacy—up to 100 LPW in some cases—and a color rendering index of 90 or more. They have excellent hot restrike capabilities and are dimmable. For outdoor work, it is also important for the lamp to be mechanically robust. The support structure in HMI lamps with the outer jacket is designed to reduce the likelihood of premature failure if the spotlight fixture is moved during location filming.
