Important safety instructions
When using your lighting equipment, basic safety precautions should always be followed,
including:
1. The fixture should only be used by qualified personnel
2. Read and understand all instructions before using
3. The equipment must not be used by children. Close supervision is necessary when
any fixture is used near children. Do not leave equipment unattended.
4. The fixture and the accessories mounted onto the fixture may heat up to high
temperatures, so please handle with care.
5. Do not operate fixture with a damaged cable or if the fixture has been dropped or
damaged - until it has been examined by a qualified service person.
6. Position the cable so that it will not be tripped over, pulled, or make contact with hot
surfaces.
7. If an extension cable is necessary, a cable with a current rating at least equal to that
of the fixture should be used. Cables rated for less amperage than the appliance may
overheat.
8. Before the fixture is cleaned or serviced or while it is not in use, it must be completely
disconnected (by unplugging the mains cable). Disconnect the fixture from the ballast
unit. Never pull on the cable itself: pull only on the connector housing.
9. Let the fixture cool completely before putting away.
10. To reduce the risk of electric shock, do not immerse this fixture in water or other
liquids. An electric shock could be caused.
11. To reduce the risk of electric shock: take the fixture to a qualified service person
when service or repair work is required. Only original spare parts must be used to
guarantee long-term mechanical and electrical operating safety. Incorrect reassembly
can cause electric shock when the lamp is subsequently used.
12. The use of an accessory attachment not recommended by the manufacturer may
cause a risk of fire, electric shock, or injury to persons.
13. HMI fixtures emit levels of UV radiation similar to daylight . The UV-radiation safety
glass is integrated into the reflector and Softbox adapter attachment. The lamp base
should never be used without a reflector or Softbox adapter attachment.

Attention: Read before starting up
- For safety reasons, always disconnect the lamp base cable from the ballast unit
before opening the fixture for any purpose (e.g. to replace the lamp).
- To ensure maximum service life of the fixture, allow it to heat up for about 3
minutes without interruption. Always heat up with ballast dimmer set to full power.
- Because the unit emits a great deal of heat, the fixture must be located at a safe
distance whenever it is facing toward flammable and/or heat-sensitive surfaces o
r
objects.
- A hot lamp must never be placed in contact with flammable materials.
- Never use the fixture improperly, and be particularly careful not to obstruct the
natural circulation of air that keeps the fixture cool. Do not cover the reflector o
r
lamp base vent holes.
- To prevent overheating, never operate the fixture with the barn doors completely o
r
almost completely closed.
- The fixture is not suitable for use in explosion-hazard areas.
- Do not operate the lamp without a safety glass.
- Like natural daylight, HMI/MSR light contains a certain proportion of UV radiation.
The safety glass reduces the UV content to safe levels for normal operating
distances. When used at close operating distance, limit the exposure time o
f
unprotected skin.
- A ballast unit is necessary to use the fixture. The ballast unit provides for the
current supply to the fixture.
These fixtures conform to the protection class I, and for this reason may only
be operated on a mains supply with kobold electronic ballast units of
protection class I.
- Protect fixtures and accessories from falling down or out.

1. Start up
1.1 General information
The lamp base without a reflector or Softbox adapter are not provided with a
safety glass. The safety glass is integrated into the reflector or Softbox adapter
and serves to protect equally against broken lamps as well as noxious UV-
radiation. The fixture may therefore never be used without a reflector or Softbox
adapter with an intact safety glass. A cut-off switch is provided to protect the DW
575 and DW 800. Always check for proper function. The fixture is constructed
according to the protection norms IP54 and can be exposed to normal rain.
However the lamp should not be exposed to splash water.
Note: When using the Softbox adapter (bare bulb) with Softboxes or lanterns,
there is no weatherproof protection.
1.2 Starting up
1) Remove reflector
2) Insert lamp into lamp base
3) Mount Open Face reflector, PAR reflector or Softbox adapter.
4) Connect lamp base cable to the lamp base and secure it by tightening the cap
screw nut.
5) Connect lamp base cable to the electronic ballast unit and secure it by
tightening the cap screw nut.
6) Connect electronic ballast unit to the earthed/grounded mains socket.
7) Set the power switch on the ballast unit to ON.
8) Press green button of electronic ballast unit or lamp base; the fixture is
switched on and operational.
9) Press red button of electronic ballast unit or lamp base; the fixture is switched
off.
Occasionally a lamp may fail to trigger; if this happens, switch the fixture or ballast
unit OFF and then ON again.
Optimum colour temperature will be reached in about 3 – 5 minutes
To ensure maximum service life of the lamp, allow it to heat up for about 3 minutes
without interruption. Always heat up with ballast dimmer set to full power.
Make sure the ventilation slots on the fixture and the ballast unit are unobstructed.
1.3 Power regulation
When the fixture is used with a kobold ballast unit, it is equipped with electronic
output dimming. This dimming function allows light output to be reduced
continuously down to about 60%. Please note that depending on the type of lamp
used, colour temperature may change with output. kobold ballast units are
equipped with an electronic control of the heating up process. It controls during the
heating up process automatically on full power until the operating temperature is
achieved.

1.4 Remote control ON/OFF
Remote control (on): The ballast units are supplied with an active remote control
mode. The function is as follows: If the operating fixture becomes switched off due
to an interruption of the mains supply, it will turn on again, as soon as the mains
supply begins to function.
Remote control (off): If the fixture should not be switched on automatically when
the current comes back, this function can be activated on the ballast unit by re-
plugging the contact bridge into another socket. The contact bridge is situated on a
printed circuit board in the inside of the unit, and may only be moved by a
specialist.
2. Operation of the lamp
2.1 Mounting and dismounting the reflectors and Softbox adapter
Before mounting the reflector or Softbox adapter, the knurled screw of the locking
mechanism (8) must be loosened by turning it counter-clockwise. A reflector or
Softbox adapter is now inserted with the marking towards the top by introducing
the 3 pins into the corresponding slots (11) and turning the reflector clockwise until
the pin (9) snaps into the locking position.
By tightening the knurled screw (8) the reflector or Softbox adapter are securely
locked. For safety reasons the knurled screw must always be well tightened.
Before taking off the reflector or Softbox adapter, the knurled screw of the locking
mechanism must be loosened by turning it counter-clockwise. By pulling the
mechanism backwards, away from the reflector, the locking mechanism is
loosened and the reflector or Softbox adapter can be turned counter-clockwise to
be removed.
2.2 Mounting and dismounting the accessories to the Open Face reflector
4-leaf barn door: Before mounting the barn door, completely loosen the knurled
knob on the locking (20) mechanism. Place the movable roller (21) on the reflector
edge (15), push down to compress the spring in the mechanism and slide the
remaining two rollers over the reflector edge. To ensure that the three rollers have
a secure hold on the reflector edge, rotate the 4-leaf barn door. Now that all 3
rollers are secured, tighten the knurled knob (20). For safety reasons, the knurled
screw must be tight during operation of this light at all times.
Conversion filter/ diffusion filter: The filter slot is part of the 4-leaf barn door.
Turn the 4-leaf barn door until the flap of the filter slot (18) is at the top. Open the
flap of the filter by the handle, insert it completely into the filter slot (18) moving it
45° sideways until the filter handle corresponds with the safety hole of the grip at
the corner of the barn door. For safety reasons check that the slot flap is
completely closed.

2.3 Mounting and dismounting the accessoires to the PAR reflector
4-leaf barn door: Unlock and flip up the top barn door claw (17) by pushing in the
marked direction. The 4-leaf barn door for the PAR reflector can now be inserted
from above in the outer fixed groove of the three lower barn door claws.
Lower the top barn door claw until it engages and locks. To ensure that the barn
door is securely fitted, rotate the barn door.
PAR lens, Fresnel lens: Unlock and flip up the top barndoor claw (17) by pushing
in the marked direction. Select a PAR or Fresnel lens and insert from above in the
inner fixed groove of the three lower barn door claws. Lower the top barn door
claw until it engages and locks. To ensure that the barn door and lens are securely
fitted, rotate the barn door.
Scrim ring: Unlock and flip up the top barn door claw (17) by pushing in the
marked direction. The scrim ring can now be inserted from above (behind the 4-
leaf barn door) in the outer fixed groove of the barn door claws. Lower the top barn
door claw until it engages and locks. To ensure that the barn door and lens are
securely fitted, rotate the barn door.
2.4 Focusing
Use the rotary knob (3) on the rear of the lamp base to adjust the focus; note the
corresponding flood and spot symbols on the lamp base indicating the adjustment
directions. By using the lamp base with an Open Face or a PAR reflector with a
mounted Fresnel lens, the complete focus range can be used. By using the lamp
base with a PAR reflector with or without mounted PAR lenses, be aware that only
a part of the focus range can be used.
Note: Gel filters can also be used instead of mounted glass filters. Attachment
clips (19) for these are located on the two wide door leafs.
2.5 Inserting or replacing a lamp
Before replacing the lamp “attention hot lamp”, switch the ballast unit OFF and
disconnect the fixture from the ballast unit.
- Remove accessories including 4-leaf barn door (see section 2.2-3)
- Unlock reflector
- Carefully pull out the reflector
- Carefully insert the lamp into the ceramic socket, align the two pins with the
holes in the socket and push it in all the way. The two spring clamps (10)on the

8
lamp socket must engage the lamp’s ceramic base. Be careful not to tilt or jam
the lamp while inserting it, and handle the lamp only by the base in order to
keep the quartz glass free of fingerprints. Any fingerprints or other marks on the
quartz glass must be immediately removed with a clean cloth moistened with
solvent or alcohol. No warranty or replacement obligation applies to lamps that
have been damaged by improper insertion.
- Before mounting the reflector or Softbox adapter check that the safety glass is
intact. Safety glasses which are scratched or otherwise damaged must always
be replaced.
- Carefully reinsert the reflector (see chapter 2.1) or Softbox adapter back into the
lamp base; push it smoothly and exert only minimal force.
Lamps of different manufacturers are subject of a certain tolerance. To adjust the
lamps in the optimal position (spot) to the reflector, the lamp can be adjusted with
the setting screw (5).
Attention! The safety glass provides protection in the event of a lamp
exploding, and UV radiation. Never use the fixture without an
intact safety glass.
