General Features

The Duo-Lite Head is designed for use with the Duo1200, Duo 2400 and Duo 4800

Packs. Operating from a nominal 230 volt mains supply only, features include:

z 650 Watt maximum modelling power.

z Two pin plug-in lamp holder.

(Recommended Halogen bulb - P2/16 hair pin, long life type.)

z Easy fitting of the standard ‘S’ series reflectors and accessories as used on all the

Bowens Prolites, Esprit, Estime and ‘S’ type Quad Flash Heads.

z Built in cooling fan.

z Modelling lamp on/off switch fitted on rear moulding of the Flash Head allowing the

modelling lamp of individual Heads to be switched off without affecting other

Heads connected to the same pack.

z UV Coated Protective Cover Glass to provide UV filtering and protection against

lamp failure.

z Optional cover glasses available including clear glass and frosted glass to provide

a diffused effect.

Operation

z Mount the Head on the selected support system. Fit the required reflector and / or

accessories. If an umbrella is to be used the umbrella shaft should be inserted

through the umbrella mounting hole and locked in position with the knurled fixing

knob (Fig. 2).

z The angle of the Flash Head may be set by using the locking handle

(Fig. 2). Support the Flash Head before releasing the handle.

z To fit a Flash Head to a Pack, first ensure the Pack is switched off and

disconnected from the supply.

Insert the tab on the front of the Flash Head plug into the socket first and then

press down firmly on the cable entry end to ensure latched retention. To remove

the plug, press the spring latch away from the plug and lift from the cable entry

end.

z Switch the Pack ‘ON’ and test the operation of the Flash Head, modelling lamp

and flash.

Fitting / Removing Reflector

z A range of reflectors are available for the Duo-Lite. To fit, slide the neck of the

reflector over the front of the flash head, align the three pegs on the reflector with

the three slots in the retaining ring, press down and turn clockwise.

z To remove the reflector press the latch knob (Fig.3) in the direction of the arrow,

turn the reflector fully anti-clockwise and withdraw.

Modelling Lamps

z ALWAYS switch ‘OFF’ the Pack and remove the connector to isolate the Head

before replacing the modelling lamp.

z If the modelling lamp is not lit but the Head switch is on and the pack controls

have no effect then:-

• Check the operation of other Heads connected to the same Pack. If these do

not work and the Pack appears to be working then check/change the Pack

modelling fuse after checking the Heads for faults or broken lamps.

• Check that the fan is running. If not then check/change the Pack modelling

fuse.

• If the fan is running then check/change the modelling lamp. As the fuse may

blow when a modelling lamp fails, always check/change the modelling fuse in

the Head if the replacement lamp does not work.

z Ensure that the Head has cooled sufficiently before touching the reflector or glass

dome.

z Remove the reflector (Fig.3) to gain access to the glass dome.

z Remove the glass dome by depressing the dome retaining buttons (Fig.3) and

lifting it away from the flash head.

z Take care removing the old modelling lamp from the holder.

z Ensure a replacement modelling lamp of the same voltage as the supply (230 V) is

used.

z Do not touch the replacement modelling lamp with fingers: use clean, impervious

cloth or paper, or the new lamp packaging materials.

z Insert the lamp into the holder positioned in the centre of the reflector.

z Hook the glass dome over one of the dome retaining buttons, depress the other

button and refit dome over the ridge in the top hat. The correct holes are marked.

Ensure that both buttons drop into the retaining holes in the dome.

z Replace the reflector as required.

z Discard the old modelling lamp safely using the packaging from the new lamp.

Circuit Protection

z Circuit protection for the modelling lamp is provided by means of a 20 mm fuse

mounted on the rear of the Head. The fuse is rated at 6.3 Amp and should never

be replaced with a fuse of a different type or rating.

z The spare fuse is retained under the printed handle insert (Fig.1). To remove the

moulding insert a finger nail under the slot and pull backwards.

Flash Tube Replacement

z A user replaceable flash tube assembly is available - Part No. BW-2980.

NOTE: Flash tubes are very delicate. Handle the assembly carefully and do not

bend the mounting legs close to the glass.

z ALWAYS switch ‘OFF’ the Pack and remove the connector to isolate the Head

before replacing the flash tube.

z To remove the flash tube first remove the glass dome as detailed above.

z The flash tube assembly can become very hot in use. Always allow time to cool

before handling.

z Unwind the twisted trigger wire from the flash tube support.

z Carefully pull the flash tube assembly away from the Flash Head.

z To replace the flash tube, hold the replacement assembly as shown (Fig.4) and

locate the three brass sockets onto the plugs in the front of the Flash Head.

z Press down evenly until all the plugs are fully engaged. Pass the trigger wire

through the hole in the trigger terminal tag and wind around the tag, ensuring that

the wire does not touch the metal top hat.

z Refit the glass dome as described before.

z Discard the old flash tube safely using the packaging from the new tube.
