hydrargyrum medium arc length iodide (HMI)

Hydrargyrum Medium-Arc-Length Iodide (HMI) lamps are gas discharge lamps used for lighting

in filming and video recording. HMI lamps have a color temperature of 5,600 Kelvin (K) to 6,000 K, which corresponds to daylight. They operate at relatively low pressure, have a short heat-up time and a high color rendering index (CRI). Since their color temperature corresponds to daylight, shots with HMI lamps can be combined with daylight shots.
