Arri Daylight (HMI/MSR Lamp Type)
Unlike an incandescent light source, where a resistive filament is used to create light, a daylight (HMI/MSR) lamp produces light from an arc (a continuous low voltage/high amperage spark). The light colour is controlled by gas mixture within the lamp, and in the instance of daylight simulation, a mixture of mercury vapour and metal halides render the light to a colour of 5500-6000 kelvin.
HMI/MSR lamps offer extremely high luminous efficiency and are cooler running than their tungsten equivalent.
HMI = Hydrargyrum Medium-Arc Iodide
MSR = Medium Source Rare Earth
