OPERATING INSTRUCTIONS DEB1200D AND DLH1200D
1) IMPORTANT INFORMATION
Read all of the following information carefully before operating the Dedolight
DEB1200D electronic ballast and DLH1200D daylight fixture.
This document contains important information regarding safety, operation and
maintenance of this system.
This equipment is intended for professional use and is to be used by trained
personnel only.
Keep the operating instructions with the equipment at all times.
The manufacturer is not responsible for damage caused by improper use or mishandling.
The DEB1200D electronic ballast and the DLH1200D light head are built in
accordance with CE and EMV-regulations EN 55015, EN 61547, EN61000-3-2
and -3, safety standards EN 60598-1, EN 60598-2-17, EN 60922, EN60350.
2) GENERAL DESCRIPTION OF THE SYSTEM
The compact DEB1200D electronic ballast is intended exclusively for use with the
Dedolight DLH1200D daylight light head.
The DEB1200D electronic ballast is equipped with active power factor correction. The
light head is to be used with a 800W daylight lamp which provides the highest possible
color rendition index RA > 92, and a color temperature of approximately 5600K.
The Dedolight DEB1200D electronic ballast offers the capability of dimming the
lamp, boosting the lamp or operating it with nominal power.
Further advantages of this electronic ballast in comparison to conventional ballasts
for daylight lamps:
- flicker free up to 10,000 frames/second*
- no camera synchronization necessary
- stable optimal color quality
- flicker factor < 2% rest ripple
- stable color temperature
- wide range of input voltages from 90-264V AC
- fluctuations of input voltage and input voltage frequency within the
above-mentioned limits have no influence on the emitted light
- over voltage cut off
- automatic fuse in the mains switch
- active power factor correction
* except high speed video cameras with „rolling shutter“ for example Phantom HD

OPERATING INSTRUCTIONS DEB1200D AND DLH1200D
The lamp is driven with a square wave AC voltage of approximately 75 cycles in
flickerfree mode. Lamp output is regulated according to preadjusted value
independent of mains and lamp voltage. Lamp amperage is regulated, further
contributing to flawless operation.
The power electronics are monitored by a temperature control circuit. Should cooling
be insufficient or in case of fan failure, the electronic ballast will switch the lamp off.
The ignitor is placed in a housing beside the lighting fixture and generates the
ignition voltage necessary to start the lamp.
Push buttons on the ignitor housing and/or identical push buttons on the electronic
ballast allow the start and stop of operation on the ballast or on the fixture.
Independent from the settings on the electronic ballast, the focusing knob on the
light fixture allows the variation of the beam angle in an extremely wide range. Using
a patented two lens system in combination with a 2-step movement of the mirror
and lenses, it is possible to achieve a focusing range unprecedented in other com-
pact light heads.
The finely tuned optical system offers an extremely clean beam - with practically no
stray light - improved light distribution in spot and flood and any position in between.
The adjustability of the beam has been enhanced by a super spot position.
The holders on the front ring of the fixture accept accessories such as the barndoor,
filter holder or projection attachment which are secured by a latch on the top left
side of the fixture.
A handle on the rear side of the fixture, which can be unfolded for operation or
folded for transport, allows for easy pan and tilt motions of the light head.
A metal noose on the right side of the light head can accept a suitable safety cable
or safety chain to connect the light head with its point of fixation when operated in a
hanging mode. If needed, the same noose can be used for a safety cable to secure
the barndoor.
3) SAFETY PRECAUTIONS
The DLH1200D daylight light head cannot be operated without the DEB1200D elec-
tronic ballast. The connecting cable (DPOW1200D) must be used between the elec-
tronic ballast and the light fixture. Maximum tilt angle is +/- 90°.
Upside down operation of the light head is not allowed and will damage the
ignitor.
A) CAUTION: MAINS VOLTAGE!
This system is built according to Safety Class 1 which requires a grounded 3-pin
connection (L, N, PE). Before connecting the ballast to the mains, be sure the outlet
meets safety regulations. If the ground connection carries any voltage, the outlet
should not be used under any circumstance. If the ground connection is missing, a
suitable grounded outlet must be found.
Care should be taken to ensure that the mains connector and mains cable are of a

OPERATING INSTRUCTIONS DEB1200D AND DLH1200D
suitable dimension (gauge) to meet the prevailing rules in each individual country.
The electronic ballast works with all voltages from 90-264 V AC.
B) DISTANCE TO FLAMMABLE MATERIAL
The light head must never be operated near flammable material.
Minimum distance to flammable material in direction of the emitted light:3m (10 ft).
Minimum distance of the light head housing to flammable material: 0,8 m (2,8ft).
The system must not be switched on or used in aggressive or explosive media.
Caution: Do not put light into transport case while still hot !!
C) OUTDOOR OPERATION
The DEB1200D electronic ballast and DLH1200D light head are built according to
Safety Class IP23 (wet location).
The light head cable and connectors are in accordance with IP67 and can be laid on
wet ground provided correct seating of the connector lock rings is assured.
D) UV RISK
The lamp used in the light head emits high UV values which present a health hazard
if proper protection is not ensured.
Do not operate the system if:
- the door of the fixture is open
- there is no front lens in the light head
- the front lens is without UV cut filter
- there is no mirror inside the light head
- internal protective shields are missing or damaged
