Key specifications

Specification	Details
Lamp / technology	575W single-ended metal-halide; HMI Fresnel

Technical reference: ARRI specifications.

Strengths and limitations

• Strengths: a continuously focusable Fresnel beam, replaceable discharge lamp and conventional barn-door and scrim control.
• Trade-offs: separate ballast and head cable, lamp warm-up, high surface temperature and a lamp-specific operating package.
• Choose it for: controlled daylight at a workable distance; compare an LED when immediate restart, low-power dimming or electronic colour adjustment is central to the job.

Practical uses

Setup	How to use this head
Small daylight accent	Use a distant stand position for an edge, architectural highlight or controlled patch through a window. The small lamphead is easy to position, but the direct-beam working distance still has to meet ARRI’s published limit.
Daylight bounce	Flood the lens to cover the chosen bounce evenly. Keep the head far enough back to respect the clearance to the illuminated surface; frame the bounce separately to control the resulting soft source.
Background separation	Place a narrow beam on a distant background element rather than increasing the whole room’s ambient exposure. A 575W head is better suited to a selected area than a broad daylight exterior.

Output and colour

The ARRI D-Series overview poster lists the following nominal centre illuminance with the 575W lamp. Distance is 10m; beam diameter is the manufacturer’s field reference for each focus setting.

Focus / beam	Centre illuminance	Beam diameter
Spot / 6°	3,215 lux	1.05m
Medium / 30°	693 lux	5.36m
Flood / 56°	290 lux	10.63m

Spot raises the centre intensity by narrowing the useful area. Use medium and flood figures when sizing a window source or diffusion frame. These are nominal manufacturer values, not measurements of a particular rental lamp; lamp age, lens condition, focus and operating mode can change the result.

The published 6,000K figure is a nominal lamp reference. HMI does not provide the continuous CCT and green–magenta controls of an RGB LED. Check the warmed lamp with the production camera and meter before choosing correction; changing ballast power can also alter colour.

Power and ballast requirements

The 575W figure belongs to the lamp. The ballast draws additional power and may draw different current at different mains voltages. Use the input label and manual of the actual ballast when planning distribution; dividing lamp wattage by outlet voltage understates the operating package.

ARRI lists the EB MAX 1.8 for this head. Confirm lamp selection, connector type, approved cable and any head-cable extensions. VEAM and Schaltbau versions appear in the catalogue; a compatible wattage rating alone does not establish cable compatibility.

A lamphead is not connected directly to mains or a conventional lamp dimmer. Feed the ballast from its specified supply, keep ventilation clear and allow it to run the lamp through its proper start and warm-up sequence. A portable power system must support the ballast’s continuous input and starting behaviour.

Control, cooling and camera operation

Focus and aim are mechanical at the lamphead. Intensity adjustment, lamp on/off, low-noise operation and high-speed modes belong to the ballast, with features depending on the ballast generation. A listing for this head does not guarantee that a rental includes DMX or a high-speed ballast.

Select the ballast’s operating mode before testing the camera. Higher lamp-drive frequency can help high-frame-rate photography, but “flicker-free” is not a guarantee for every shutter angle and frame rate. Test the intended combination at working output; lamp or ballast sound can matter in quiet interiors.

Modifiers, rigging and the working package

Item	Working-package detail
Barn doors / scrims	Use the 197mm barndoor and 197mm scrim references for this model; do not order by lamp wattage alone.
Diffusion / bounce	Use a separately supported, heat-appropriate frame or bounce with the required clearance. Verify even coverage rather than judging only the bright centre.
Support	The head is approximately 5.9kg before loose accessories. The 28mm pin identifies the mounting interface, not the load capacity of the complete support.
Cable and ballast	Include the correct head cable, ballast, mains lead, cable management and safe access in the order.

ARRI’s D-Series manual gives 8.6m as the minimum distance to illuminated persons, objects and surfaces for the D5, plus 0.5m around the fixture to flammable material. Follow the lamphead label and manual for the particular unit. Keep the lens, protective parts, latch and interlock in serviceable condition; a damaged enclosure is a reason to take the head out of use.

Alternatives and related fixtures

Fixture	Why compare it
ARRI M8	A lensless MAX-reflector alternative; compare the beam and useful coverage at the same distance, not lamp wattage alone.
ARRI Orbiter	A smaller full-colour LED package with interchangeable optics when controllability and quick colour changes matter more than discharge-lamp output.
ARRI Compact 6000 Plus	A larger daylight Fresnel when the required distant coverage and exposure exceed this head’s working output.
ARRI True Blue D12	A larger 1.2kW daylight Fresnel with a different lamp base, accessory sizes and supporting package.

What people are saying

In ARRI’s D-Series presentation, cinematographer Bill Holshevnikoff demonstrates the smaller D5 and D12. The presentation is manufacturer material and is useful for seeing the head, focus and handling arrangement in context.

Rental and used-fixture checks

• Confirm the exact lamp, ballast, head cable and connector version before collection.
• Inspect the Fresnel lens, reflector, protective assembly, lamp holder and door interlock; do not bypass an interlock to test a damaged head.
• Run the lamp long enough to check stable colour, focus travel and the selected ballast mode.
• Check the tilt brake, sliding yoke and accessory latch with the actual barn doors fitted.
• Test the planned frame rate and shutter with the complete operating package, and include lamp hours and spare-lamp availability in a used purchase.
