TECHNICAL DESCRIPTION
Flashlight F 250
Light Units of the HEDLER F range are designed for professional use. They are assembled by applying precision methods and tested individually
for function and quality. The Flashlight HEDLER F 250 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 can be turned for either right or left hand use. On its front side, the aluminium housing holds the Borofloat™ safety glass.
AdditionalIy there is the QuickFit adapter (compatible with Uni-Adapt system) for attaching reflectors.
The Flashlight HEDLER F 250 uses AC of 220 - 230 V and the modern Tungsten Lamps 200 W as a pilot light. The flash light source is a quartzflash bulb with daylight quality and a maximum power of 250 Ws.
The Flashlight HEDLER F 250 has a Setting-Safe-Function (SSF). It is activated by pressing and holding down the TEST switch for more than 3
seconds. A signal tone indicates, that the SSF has been activated; this saves the settings even when the light unit it is switched off and on, and the
user will not lose their valuable information! An unwanted change of the Light Units settings isn´t possible. The function is deactivated by pressing
and holding the TEST switch for more than 3 seconds.
FLASH OUTPOWER and FLASHFUNCTIONS
The flash light output power of the HEDLER F 250 is infinitely adjustable by 4 f-stops. Reducing the flash light output power charging is
automatically done by the electronics, no manual flashing to unload the flash light unit is necessary.
Under maximum flash light output power, the longest flash duration lasts 1/850 second, and this allows the use of a 1/500 second as sync-time.
The „short“ 1/500 second is extremely helpful while photographing Portrait and Fashion: it can prevent „blurred“ photographs even when
working without a tripod. Please check your camera to find out which sync-time can be used; if you use a shutter speed shorter than your
camera´s sync-time while using flash lighting, your photographs will be darkened or underexposed on their longer side.
The HEDLER F 250 can be flash fired with the sync-cord or Photocell. If you use more than one flash light unit, the synchronized flash firing
can be done in two ways:
a) one flash light unit will be connected to the camera by a sync-cord, which has to be plugged into the Socket SYNC. When shooting the
photograph, the camera triggers the sync-cord connected flash light unit and every other flash light unit with Photocell switched on will be
released synchronized;
b) connect an IR trigger to your camera and switch on the Photocell at every flash light unit that must/should be released synchronized; when
shooting the photograph, the IR trigger will be released by the camera, and every flash light unit (that receives a strong enough IR light impulse)
will be released synchronized. For technical and practical reasons, we recommend this flash release version.
To assess lighting and shadow ratio/impact the F 250 is equipped with a 200 W pilot or modeling light. With switch PILOT SET set to position
I, the pilot light output power will change proportionally and continuously when flash light output power is changed. Set to position II the pilot
light output power will also change proportionally when the flash light output power is changed, but in addition: the pilot light will automatically
turn-off during the re-/discharging time of the F 250. After re-/discharging, the pilot light will automatically turned on again to indicate readiness
for flash firing (useable as an opitical flash firing control).
In certain circumstances, such as when the material has shiny surfaces or is deep/dark black, focusing the lens can be a problem. In such a
situation, the PILOT RANGE switch can reduce the output power from 100% (position I) or 50% (position II); this is only effective if the
PILOT SET switch is set either to position I or II). Using the PILOT RANGE switch does not change the flash light output power setting!
The ACOUSTIC CONTROL switch, in position I or II, allows the successful control of different acoustic tone flash firing ready/flash firing.

Description
Photocell switch
Photocell is switched off
Photocell is switched on; the F 250 will only be released if it receives a strong enough light or IR light impulse
Photocell is switched on and ignores some camera´s metering pre-flash; the F 250 will be released when the camera´s
main flash is released (if the main flash is released not later than 1/500 seconds after the pre-flash was released)
Pilot Set switch (=Modeling light switch)
Pilot light is switched off (prevents possible reflections on shiny materials caused by the pilot light)
Pilot light is switched on + adjusted proportionally to flash light output power without flash re-/discharging indication
Pilot light is switched on + adjusted proportionally to flash light output power with flash re-/discharging indication (if
the flash light unit has to be re-/discharged after changing the flash light output power or after flash firing the pilot light
is automatically turned off until the F 250 is ready for flash firing)
Pilot Range switch (Pilot light output power additional function)
Pilot light output power additional function is switched off
Pilot light output power additional function is switched on - pilot light output power is set to 100% without changing
the actual flash light output power setting
Pilot light output power additional function is switched on - pilot light output power is set to 50% without changing the
actual flash light output power setting
Acoustic Control switch
Acoustic Control is switched off
Acoustic Control is switched on - a repeated tone is followed by one longer tone which indicates the F 250 is ready for
flash release after changing the flash light output power or after successfully releasing a flash
Acoustical control is switched on - one single tone indicates the F 250 is ready for flash release after changing the flash
light output power or after successfully releasing a flash
5
Test switch - flash firing manually, refer to page 1 for further information about function
6
Digital Indicator - 1/10 f-stop graded - to adjust the flash output power very precisely between two flash lights
7
Wing bolt incl. friction brake - open the wing bolt by a counter-clockwise turn and the tilting of the F 250 can be
adjusted to your required lighting angle. Always secure the wing bolt and friction brake with a clockwise turn to avoid
unwanted movement or damage to the HEDLER F 250 and/or injury to the user

Pilot light fuse F 2 A - please refer to page 4: Necessary precautions and To replace the fuse F 2 A (flash bulb):
ALWAYS use F 2 A Replacement Fuses supplied by Hedler Systemlicht GmbH
14
Flash light output power rotary control - allows the infinitely variable setting of the flash units power over 4 f-stops; it is
scaled in f-stops, which means, the „distance“ - for example - between -3 and -2 has the value of approx. 1 f-stop
Example:
• HEDLER F 250 set to position -2 / digital indicator shows 3, your light meter indicates f-stop 8 and 3/10 (=f-stop 9)
• for your actual lighting idea you need f-stop 11 and 3/10 (=f-stop 13)
• turn your flash light output power rotary control from position -2 to -1 / digital indicator shows now 4 instead of 3
• please do another light metering
• your light meter should display approx. f-stop 11 and 3/10
Please note:
Because of your Studio situation (colour of the wall, size, reflections, etc.) and the combination with additional flash
light units, it may happen that a changing of the flash light output power (which will be displayed additionally by the
digital indicator) does not lead to the expected f-stop increase/decrease. This is not an error of the system but the
result of the conditions within the situation. In that case please adjust the flash light output power rotary control until
light metering shows the needed f-stop value.
15
Spring-secured pre-locking - is used to prevent unwanted disconnecting from a light stand or a wall boom with a 5/8“
male adapter; to disconnect you must press the pin and lift the complete light unit at the same time
16
5/8” Quick-Lock Light Stand Attachment - allows use with every secure and sufficiently strong light stand (ALWAYS
check the light stand´s maximum load capicity) with 5/8“ male adapter
17
Wing bolt - open the wing bolt by a counter-clockwise turn and the horizontal rotating of the F 250 can be adjusted to
the required position. ALWAYS secure the wing bolt with a clockwise turn to avoid any unwanted movement of the F
250 around the horizontal axis (if connected to an upright standing light stand)
