GENERAL INFORMATION
Thank you for your selection of one of the most effective studio luminaires, the LED-77-11. This high
performance luminaire should provide many years of low cost operation. The LED-77-11 is designed
to maximize "throw" or "punch" by collimating the light into a narrow beam (+/- 5.5 dgr.) for throw,
then the desired light pattern is achieved by use of gels or holographic filters to produce the
desired spot size. Asymmetric beams are a reality with horizontal to vertical ratios of 6-1 being
the norm. The 10x60 horizontal film can spread the light to several news anchors from one fixture.
Unwanted spill onto monitors or illuminating a standing talent is effective with the 5x30 vertical filter.
Side glare is controlled with optional honeycomb. The luminaire provides a mounting slot for
holding gel frames and/ or honeycombs. The LED-77-11 performs like a fresnel or a soft light for a fraction
of the energy. The LED-77-11 draws a mere 85 Watts.
The LED-77-11 is offered in tungsten (3200 K) or daylight (5600 K).
The LED-77-11 is available in full power, voltage dimming, analog/on board dimming and DMX dimming.
LED-77-11 housing is made of aluminum and powder coated in non-reflective black. Accessories are
made of steel and alloy aluminum. Standard luminaires are equipped with detachable 10' long power
cords. Each 120 volt cord is equipped with Edison 3-prong connectors. Other voltage models are
shipped without plug unless specified. Fused power receptacles are supplied for the 120 volt
models. Adjacent fixtures may be powered with this connector so long as the load does not
exceed 4 amps. (fig. 2) The switch controls the power to the one fixture. Power to the luminaire
is indicated when the switch is lit. Ordinary grip devices allow stand mounting as well.
CAUTION
Do not stare at the light source.
The LED-77-11 must be mounted in vertical orientation, as shown in fig1. This is to insure cooling of
the LEDs through the ventilated case. Over heating will cause premature failure.

LED77 shown with the standard "Near" gel frame
and honeycomb holder. Mounted to it is the
optional "Extender Kit" which will retain
a honeycomb and a gel frame in the "Far" position.
The extender kit is furnished complete with fasteners
and an Allen wrench. It is factory assembled when
ordered with fixtures.

ACCESSORIES
The proper use of accessories will allow this luminaire to operate as a highly specular key light and as
a directional soft light source and every point in between. (fig 5&6) The LED-77-11 provides a slot at
the aperture which will hold a gel frame and a honeycomb. With it's 11 degree beam angle the LEDÂ77-11 is suitable for distant front and back light applications as well as key light and multiple back
light applications through the use of shaping gels. (fig 8) Shaping gels also allow for minimum flair
onto monitors or provide for standing talent illumination. (fig. 7) Honeycombs and gels with
laminated frames are available for the basic LED-77-11 and fit into the furnished aperture slot.
Laminated gels as well as bare gel frames are available to allow use of non-standard gels.
The most effective use of the LED-77-11 for front light, key light and soft fill light is with the extender
honeycomb-gel accessory kit. (fig 4) The placement of gels in the "far" position provides for beam
overlapping and gives the appearance of a single source of light while eliminating multiple shadow
effects. Honeycombs eliminate side glare and make for easier tele-promptor perception. Laminated
gel assemblies are available for the larger far aperture position as well as bare frames.

INSTALLATION:
Remove the luminaire from the shipping carton and inspect for any damage during shipping.
If attenuators are ordered they may be installed in the aperture. If so, loosen the accessory
slot cover retaining screws and slide the cover back to expose the slot.
It is advisable to bench test the fixtures before installation but a few precautions are in order.
Make certain that the fixture cooling slots are not blocked when lit. Adjust the yoke so that
the body of the fixture is tilted when on the table. This is important because the LEDs are
cooled by convection of air through the body of the fixture. Do not block the vent slots.
Do not place the fixture horizontal or mount with the yoke horizontal as overheating can
occur which will shorten fixture life. When testing the fixture up close make certain not to
look directly at the light sources from close proximity. It is good practice to install the filters
to be used before turning on the luminaires. Install the power cord and plug into 120 volt
service. Place the fixture so as not to block the cooling vents and turn on the switch.The
fixture has a 2 second delay on starting. If the fixure has power the switch will be lit.
The LED-77-11-DAN version may be dimmed with 0-10 volt signal via the BNC connectors
and one signal source may dim a number of fixtures by connecting fixtures together with
BNC cables. DMX signals may be decoded to produce 8 or more individual channels
per shoebox decoder equipped with BNC outlets. Each channel is considered a separate
signal source. Local dimming control is provided by a dimmer controller with a
local / remote selector switch.
Next, the hanging means should be mounted on the yoke with a 1/2" bolt supplied with
the "C" clamp and or stem. With the stems and clamps attached, hang each assembly
in the desired location on the 2" pipe grid or other qualified hanging system. Immediately
add a safety cable as per fig. ( 9 )
The light sources cannot be changed in the field. Contact the factory for assistance.

DIRECTIONS
Fixtures equipped with detachable power cords contain fuses which are rated at 6 Amps
@ 125 Vac. To replace fuse remove power cord exposing the receptacle as shown in fig.
10. Make certain there are no other cords attached to the fixture. Using a small flat screw
driver, pry up the fuse holder shown in figure 10. Replace the fuse in the active slot and
snap the fuse holder back into place. Use only fast acting type 217, 5 x 20 mm , 6 amp
fuses.
