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

Arri Pocket Par

A small and efficient unit that is useful where space is limited.

Arri X Light

Hard shadows and high contrast.

Arri Fresnel 2500W

The Arri Compact 2500 Fresnel is a film and video location basic. Despite small size, the lenses produce good output and light distribution.
