Dedolight DLH1200D

Last Updated 3 hours ago

Overview

Product views: Dedolight California. Select an image to enlarge.

The full package includes an approved lamp, DEB1200D-family ballast and matching head cable. The compact-looking lamphead is still a substantial load once large optics and cable forces are added.

Key specifications

Specification	Details
Source	Discharge lamp with aspheric focusing optics
Power reference	1,200W lamp class
Colour / white-light range	Daylight; approved DL1200DHR lamp
Native beam	5–56°
Optical accessory family	1200
Cooling	Passive head; electronic ballast cooling separate
Weight reference	Approx. 10.5kg head; excludes the complete rig
Control	Mechanical focus; dimming/DMX depend on the approved ballast
Working package	Head, fitted optics, support, appropriate power electronics and cables; battery/AC accessories depend on configuration

Strengths and limitations

Strengths

• Large daylight source with wide-to-tight focus.
• Dedicated large projection and beam systems.

Limitations

• Heavy head, ballast and optics.
• Substantial electrical load and discharge-lamp requirements.

Practical uses

Setup	Working approach
Distant daylight	Focus to the whole action area and inspect edge exposure.
Large pattern	Select the DP1200 lens and shutter/gobo module for throw and image size.
Reflected accents	Align each reflector from camera and check the final subject exposure.

Set the head position for the direction and shadow first, then choose focus and accessories for coverage. A sharp gobo or precisely shuttered image needs imaging optics; closing barn doors around a small spot does not create the same optical result.

Output and colour

The documented ballast dimming range is 50–100%, with a 1,000Hz setting for appropriate high-speed use. That frequency is an operating condition, not a guarantee for every camera and shutter. Confirm the actual ballast revision and test the intended shot.

For a useful comparison, record colour setting or lamp, dimming level, optic, focus position, distance and illuminated area. Measure after diffusion or reflection when that is the working setup. Wattage, centre intensity and coverage describe different parts of the result.

Power and batteries

Use the approved discharge lamp, matching DEB ballast and correct head cable. The DLH200DT, DLH400DT and DLH1200D use different power packages. Head wattage is lamp power, not a complete specification of AC input, power factor or inrush.

Follow the documented connection, strike, cooling and relamping procedure. Keep protective optics and interlocks in service, and do not operate a discharge lamp with damaged protection. Support the ballast and cable independently of the head’s tilt mechanism.

Control, cooling and camera operation

Control path	Operating notes
Focus	Mechanical beam adjustment at the lamphead.
Dimming/DMX	Provided through the documented ballast options and within the approved lamp-power range.
High-speed	Frequency selection and lamp condition affect camera results. Test the actual ballast, lamp, frame rate and shutter rather than relying on a general flicker-free claim.

Cooling reference for this head: Passive head; electronic ballast cooling separate. Listen to the complete working package, including its controller or ballast, rather than checking only the head.

Modifiers, rigging and the working package

Item	Compatibility and working notes
Accessory family	1200-size optics; these are a different scale from DP400/A-size.
Projection	DP1200-family lens and approved shutter/gobo/iris assembly.
Beam control	Model-specific barn doors and wide-angle/parallel-beam attachment.
Support	Include the optic, cable pull and controller arrangement in the working load.

Aspheric focusing optics are different from a conventional Fresnel. Check the actual accessory’s compatibility list, locking method and lens choice. A brand name or similar front diameter is not enough to establish fit.

Fit the intended front accessory before choosing the stand position. Check tilt clearance, balance, cable movement and independent support for any external electronics. Use the documented mounting hardware and appropriate secondary retention for the installation.

Alternatives and related fixtures

Fixture	Reason to compare
Dedolight DLED30-D	Wide native focusing range. 320W published system reference; 1200-size optical system.
Dedolight DLH400DT	Precise focus and substantial projection ecosystem. 400/575W approved lamp and ballast configurations; A-size optical system.
Dedolight DLED10-D	Larger daylight package than compact DLED heads. 300W class; product detail lists 308W; A-size optical system.

Classic Dedolight DLH4: the original low-voltage tungsten alternative with a separate supply. Compare the full power and accessory package, rather than the bare-head price.

Rental and used-fixture checks

• Inspect the approved lamp and record lamp hours where available.
• Verify ballast model, power/frequency modes, head cable and connector condition.
• Check protective lenses and interlocks, then test the complete warm package with the production camera.

Confirm availability of service and replacement parts with the relevant supplier before buying older equipment. Check the actual kit contents against the shot: a missing controller, imager, lens or cable can matter more than a low head-only price.
