1. MAIN FEATURES
4LIGHT is an LED panel housing a total of 96 high power LED. It has been specially designed and its
colorimetry calibrated for professional photography, cinematography and television industry use.
4LIGHT main innovative features are:
•Variable Colour Temperature
•Stable colour dimming
•Green/magenta bias control
•Very high light output
•Low power draw
•High CRI digitally calibrated light
•V-lock mount battery operated
•Lightweight lamp head
NOTE ABOUT MEASURING COLOUR TEMPERATURE (CCT)
4LIGHT incorporates the innovative THELIGHT technology based on high power LED triplets + Fresnel
lens + CPU control software to obtain the wide range of calibrated colour temperatures combined
with a high colour rendering index CCT.
We must remark that colour meters in use today are designed for a full spectrum source such as
incandescent lights and therefore cannot be used to accurately read the correlated colour
temperature (CCT) of the light emitted by THELIGHT and other LED light fixtures.
The eventual diversions to green display as CC10M or CC15M in hand-held colour meters are due to
these unaccuracy on reading of the light emitted by LED and must not be considered.
THELIGHT guarantees pure white light and correct colorimetry of the light delivered by its high power
LED luminaries which have been calibrated in laboratory according to CIE 13.3-1995 international
standards for measurement of the CRI and chromatic coordinates (x, and CIE-1931).
The reliability of this digital equipment is supported by the calibration THELIGHT has made in
laboratory by spectrophotometer, which precision is half-yearly calibrated according to the National
Institute of Standards (NIST) of the United States and of the Physikalisch-Technische Bundesanstalt
(PTB) of Germany.
In order that the advanced THELIGHT luminaries could be used together with other light sources,
THELIGHT has accurately calibrated both the CCT and the chromatic coordinates to match them with
traditional light sources following tungsten and daylight standards.
The digital Control Unit allows a further and precise green/magenta correction along the whole scale
of colour temperatures.

2. Connect a battery on the V-lock mount
Either the V-lock mount or the XLR4 receptacle can be used for powering the 4LIGHT by battery.
Any battery form 9 to 36 V can be used.
Relevant information on Battery use
Use only original chargers. Don’t short the battery. Respect the service and the safety manual of
the battery.
When powering the 4LIGHT through the XLR4 connector located at
the back of the VDC Control Unit check the proper polarity as shown
in the picture at the Control Unit bottom.
To ensure maximum performance of the 4LIGHT equipment use only
high-load capacity batteries with a high continuous draw meaning a
Discharge Current of at least 9A..
NOTE:
To power the 4LIGHT lamp head through mains power a power supply of at least 14A
and 9 to 36V output must be used.
Danger
To avoid electric shocks and/or damages in the equipment the
power switch located at the VDC Control Unit front panel must be off
before connecting or disconnecting cables.
3. Connecting VDC Control Unit and lamp head through the extension cable
Connect the connector in the circular
receptacle at the VDC Control Unit front
panel.
Verify the correct alignment of the
connectors before inserting them.
Rotate the locking ring until it clicks into
the lock position.
Connect the same way the other end of
the extension cable in the input
receptacle coming out from the lamp
head.

12
Disconnecting the extension cable
Grab the connector firmly, turn the ring to unlock it and pull to extract it.
NOTE:
The lamp heads can operate with a maximum extension cable length of 10 meters.
NOTE:
The extension cable is provided with two equal connectors in every end: both can be
connected either in the VDC Control Unit or in the lamp head.
NOTE:
The 4LIGHT lamp head can be battery powered with the VDC Control Unit included in
the kit or mains powered with the optional VAC Control Unit.
4. Placing the VDC Control Unit in the stand mast
You can place the VDC Control Unit in the stand mast for a handy use close to the lamp head.
To do so you will need to use a regular Super Clamp (not included in the 4LIGHT kit) and insert
the Hexagonal 5/8” (16mm ) baby spud.
Once installed the hexagonal spud just
slide the holder located at the VDC
Control Unit bottom over the spud plate
until properly seated, as shown in the
picture.
5. Security cables
The lamp head is provided with
several holes specially design to
insert one o more 5mm snaps and
their safety cable.
Warning
When the lamp head and any other component is mounted in a
hanging position it must be secured with a safety cable rated at a
minimum of ten times the weight of the light fixture including its
accessories.

5. DIGITAL ADJUSTMENTS
The VDC Control Unit doubles as power supply and digital remote controller of the following light
parameters through its programmed CPU:
•Calibrated Colour Temperature variation
•Stable colour dimming
•Green/magenta bias control
Turning the Power On/Off
Turn on the equipment by switching the power button towards the Iposition. Switch the power button
towards 0 position to turn it off.
The light settings always remain stored when the VDC Control Unit is powered off.
Danger
Both the lamp head and the VDC Control Unit are electrically protected
against power failures but to avoid possible electric shocks and/or
equipment damages make sure the power switch located at the VDC
Control Unit front panel will be off before connecting or disconnecting
cables.
In case of extreme over tension replace the 15Ah fuse from inside the fuse
holder located at VDC Control Unit back. (see picture on page 9)
NOTE:
If a power failure would happen or the cable would be accidentally disconnected the VDC
Control Unit would entry on Error mode and the number 8 would show in the digital
display.
To reset the equipment and resume the light values turn the switch power off, connect
extension cable and switch on the power button.
COLOR TEMPERATURE Variation
Colour temperature can be easily increased or reduced through the +/- buttons located at the VDC
Control Unit front panel. Above them a digital display indicates at all times the selected colour
temperature. The value 3.2 corresponds to 3200K and the value 3.3 to 3300K and so on.
Push the + button to increase colour temperature or push the – button to decrease it. If you keep
pushed any of the buttons the you will get a continuous variation.
NOTE:
Every push on the buttons will increase or decrease the colour temperature in calibrated
increments of 100 Kelvin.
TURBO
By activating the TURBO button (a blue LED lights up on the screen of the Control Unit) maximum
light output is achieved in the colour temperature selected and the value 9 will appear on the
dimmer display.

14
DIMMER Light intensity variation
The dimmer of the VDC Control Unit is totally digital and guarantees the regulation of light intensity
with minimal changes in the selected colour temperature.
Light intensity can be easily increased or reduced through the +/- buttons located at the VDC
Control Unit front panel. Above them a digital display indicates at all times the selected dimmer value
from a minimum of 1 to a maximum of 9.
Push the + button to increase light intensity or push the – button to decrease it. If you keep pushed
any of the buttons the you will get a continuous variation.
NOTE:
Every push on the buttons will increase or decrease the light intensity in calibrated
increments of !stop.
-/+ GREEN Green/magenta bias control
Green/magenta bias switch located at the VDC Control Unit front panel lets you easily alter the
colour of the light emittting at any colour temperature towards green or magenta in increments of -
/+ 1/8 and ".
When this switch is not in the standard position a green LED light turns on in the VDC Control Unit to
warn that the light emitted no longer guarantees the correct chromaticity.
NOTE:
THELIGHT guarantees the correct colorimetry for light emitting from their high power
LED light fixtures, calibrated in the laboratory according to current international
standards of the CIE 13.3-1995 for the average CRI and the chromatic co-ordinates (x, y
CIE-1931). This certifies that our luminaries have no green/magenta deviation.
NOTE:
Full adjustment is possible in a range of colour temperatures from 3900K to 5800K.
From 2800K to 3900K and from 5800K to 8500K the adjustment is possible only on
1/8 and "plusgreen.

6. DMX 512 CONTROL (only VDC Control Unit DMX)
THELIGHT lightning fixtures have been designed for a full DMX control from the 5-pin DMX port
located at the back of the VDC Control Unit DMX.
Connect the DMX cable coming from your console into the DMX IN male connector located at the
back fo the VDC Control Unit DMX. Beside the DMX IN there is also a DMX OUT connector to daisy-
chain fixtures.
Adressing channels
Push both + and - COLOR TEMPERATURE buttons at the same time and then switch on the power
button. Wait a few seconds for the three digital displays to blink.
Now you can define the start address. To do so just push the + or – DIMMER buttons to increase or
decrease the first fixture address. Once you have chosen the desired address number push the
TURBO button to save the selection.
Keep in mind the following points regarding DMX control:
!THELIGHT DMX protocol uses 3 channels per fixture
!After the DMX address is entered the Control Unit will automatically assign the following two
channels.
!If you wish to control several THELIGHT fixtures at the same values you will have to set them
to the same address.
!If you wish to control several THELIGHT fixtures independently you will have to offset their
address by 3 channels. Example:
fixture1 address 001 -- fixture2 address 004 -- fixture3 address 007
DMX Channels
When you connect your console to the VDC Control Unit DMX you will be able to control THELIGHT
fixtures through 3 channels:
!Channel 1 (start address) – COLOUR TEMPERATURE
From 2.5 to 6.5 (from 2800Kelvin to 8500Kelvin)
Fader at 0 2.8 means 2800Kelvin
Fader at 100 8.5 means 8500Kelvin
!Channel 2 (start address + 1)– DIMMER
!Channel 3 (start address + 2)– GREEN/MAGENTA correction
fader at 0% -1/4 Green
fader at 25% - 1/8 Green
fader at 50% standard position (green/magenta at 0)
fader at 75% +1/8 Green
fader at 100% +1/4 Green
NOTE:
Do not use microphone cables or other general purpose two-core cables designed for
audio or signal use. They are not suitable for DMX 512. Problems due to wrong cabling
may not be immediately perceptible.
Microphone cables may appear to work fine, but systems built with such cables may fail
or be susceptible to random errors.
Cable must comply with RS-485 DMX protocol (EIA485).
NOTE:
A DMX terminator should be plugged into the final, empty, OUT connector of the last slave
on the daisy chain.
A terminator is a stand-alone male connector with a built-in 120 !resistor, matching the
cable characteristic impedance, connected across the primary data signal pair.
NOTE
for Avolites
consoles users:
THELIGHT luminaries DMX working personality can be configured to be
recognised by Avolites consoles.

7. MECHANICAL ADJUSTMENTS
Beam angle variation
Hold the lamp head from the outer segments and bend it in or out to the wanted concave or convex
shape. Choose the light beam angle you need and the lamp head will remain at the chosen setting.
When the lamp head is positioned at standard flat setting the light beam angle is 35º.
The maximum light beam angle is given when the lamp head is bend at its more convex setting.
Barn doors installation
Place the barn door axle into the external lamp
head segment grooves. Then insert one end of
the axle into the hole located at the lamp head
exterior segment as shown in the picture.
The right mounting position is achieved when the
product name is visible facing outwards.
Insert the other barn door axle end into the
opposite hole located at the lamp head exterior
segment.

17
Quick link diffuser installation
To assemble the diffuser insert the four
magnets in their respective holes to set-
up a diffusion box as shown in the
picture.
Position the lamp head in its standard flat
setting.
Align the top diffuser box magnets with
their respective screws located on the
lamp head.
Do the same thing with the low magnets
and their power will automatically fix the
diffuser to the lamp head.
NOTE:
The diffuser softens and broadens the light beam, yet retains general beam shape with
minimal colour temperature shift. Excellent for softening harsh edges.
The transmission lost is 2/3 of a stop.
NOTE:
The diffuser has been designed so that when installed allows the lamp head to bend and
focus the beam angle.

CHROMATITY COORDINATES DIAGRAM
(x, y CIE-1931)
Shown on the diagram are the THELIGHT lamp head chromaticity coordinates (x, y CIE-1931) feed and digitally controlled
by its Control Unit and they are compared with the reference illuminants. These reference illuminants are the Planckian
locus radiator set below 5000K and the CIE daylight reference is set over 5000K. The Planckian locus radiator
references the chromaticity for several tungsten lamps colour temperatures while the daylight locus typify daylight type D
illuminants.
The diagram evidence the light emanated by THELIGHT luminary at every colour temperature entirely matches with the
described locus reference so that the colour of the light produced is essentially the same as incandescent and daylight. It
is also remarkable the minimum green/magenta deviation over the locus reference along the range of colour
temperatures (means minimal difference between THELIGHT chromaticity coordinates and the ideal reference line).
