Thank you for choosing a Hedler light unit and your
confi dence in the Hedler light system. Please, read
the following technical informations carefully
before using the light unit.
Codes are given in <Brackets>.

TECHNICAL DESCRIPTION

Light units of the HEDLER DF range are designed for professional use, they are assembled by applying precision methods and tested individually
for function and quality. The focusable daylight HEDLER DF15 is provided with an integrated U-bracket and a friction brake and a 5/8" Quick-
Lock light stand attachment. After loosening the hex key screws by approx. 2 turns, the U-bracket can be moved back and forth in its keyway
for gravity adjustment and it is turnable for right and left hand use.
The focusable daylight HEDLER DF15 uses AC of 230 - 250 V and the modern metal halide 150 W SE T bulbs, which can be re-ignited after 2 - 3
minutes while the cooling down has started by switching-off the light unit. As a special feature, the HEDLER DF15 does not have a fan, which
means it suits ideal for original sound recording.
On its front side, the aluminium housing holds the Fresnel lens with its protective grid. AdditionalIy there are the Uni-Adapt studs and the
QuickFit adapter for attaching refl ectors. Interchangeable refl ectors with bayonet ring can be attached in the following way: place the rim of the
ring into the guide grooves of the upper studs and the round opening over the cone-shaped bolt, and lock it by a turn to the left. To attach the
rotatable 4-Leaf barndoors or a MaxiSoft folding refl ector, place the rim of the ring into the guide grooves of the upper studs, and then push
the complete refl ector towards the QuickFit´s cone-shaped bolt until the ring locks in the bolt´s groove. Detach the refl ector by lifting the
QuickFit´s handle, moving the lower side of the refl ector away from the light unit´s housing, and then lifting the refl ector´s ring out of the guide
grooves of the upper studs.
On the opposite side of the housing, one will fi nd the ergonomically incorporated handgrip, the cable and the main switch. Additionally you will
fi nd on the backside of the housing the focusing turning knob, which allows to adjust precisely and intuitively the size of the light beam from
spot- to fl oodlight setting.
In addition to the parabolic refl ector, bulb socket and ignitor, the housing accomodates the electronic ballast, which supplies stabilized voltage to
the bulb, ensures fl icker-free light of constant intensity and a colour temperature of app. 6000 K. Besides that, it will extend the average bulb life
by app. 20 percent and reduce the power consumption by about 12 percent. Ignition is effected by 1 x 5 KV symmetrically, faulty bulbs will be
detected and switched off automatically. RF interference reduction meets all applicable EN 61000-3-2 standards.
