F8 Fresnel Introduction
Introduction: If you are looking for dramatic, eye-popping blacklight effects,
your fixture needs to emit true 365nm ultraviolet light. Most LED blacklights
emit 385nm to 400nm, producing an inefficient output requiring added
filters and lower output. Zylight’s F8-B2is the only fixture that combines our
proprietary Tru365™LED module with the flexibility and control of a focusable
glass Fresnel lens. Our second generation chip is 3x more powerful than the
first, delivering more punch at longer distances.
The F8-B2features two output modes with Boost mode producing the
maximum output while running the active cooling fan on the rear of the
fixture. Silent mode reduces the output (still 1.5x greater than previous
version) and disengages the fan for those seeking silent operation. The
F8-B2is capable of emitting a powerful narrow band of Tru365™ UV light with
no lenses to change, no filters to check, and no fixed beam patterns to limit
your creativity. The F8-B2is part of Zylight’s pursuit of high quality, intelligent
lighting fixtures. The F8-B2can also be controlled manually, wirelessly, or via
DMX controller.
Every F8 LED Fresnel has been thoroughly tested and has been shipped
in optimal operating condition. Carefully check the shipping carton for
damage that may have occurred during shipping. If the carton appears to be
damaged, carefully inspect your fixture for any damage and be sure all
accessories necessary to operate the unit have arrived intact. If damage
has been found or parts are missing, please contact our customer support
number for further instructions. Do not return this unit to your dealer without
first contacting customer support.

Safety Precautions Cont.
• Do not attempt to operate this fixture if it becomes damaged.
• During long periods of non-use, disconnect the fixture’s main power.
• Always mount this fixture in safe and stable matter. Always use a safety cable as
part of a secure installation. This includes securing the barn doors with a safety
cable.
• Power-supply cords should be routed so that they are not likely to be walked on or
pinched by items placed upon or against them, paying particular attention to the
point they exit from the fixture.
• Cleaning: The fixture should be cleaned only as recommended by the manufacturer.
See cleaning details below.
• Heat: The instrument should be situated away from heat sources such as
radiators, heat registers, stoves, or other appliances (including amplifiers) that
produce heat.
• Do not leave the Fresnel lens pointed directly at the sun. The sun, will focus
energy back through the lens onto the LED module (much like a magnifying glass)
and damage the LED module permanently.
• The fixture should be serviced by qualified service personnel when:
A. The power-supply cord or the plug has been damaged.
B. Objects have fallen, or liquid has been spilled into the instrument.
C. The instrument has been submerged in water
D. The instrument does not appear to operate normally or exhibits a
marked change in performance.
Cleaning
Due to fog residue, smoke, and dust, cleaning the internal and external optical lenses
must be carried out periodically to optimize light output.
1. Use normal glass cleaner and a soft cloth to wipe down the outside casing.
2. Clean the external optics with glass cleaner and a soft cloth as necessary.
3. Always be sure to dry all parts completely before plugging the unit back in. Cleaning
frequency depends on the environment in which the fixture operates (i.e. smoke,
fog residue, dust, dew).

Boost/Silent Output Modes: The F8-B2may be set at two different output levels for
operation. The default mode from the factory is Boost and has the maximum output
level. Boost mode enables the fan on the back while the F8-B2is turned on. The
cooling fan keeps the F8-B2within the operating temperature specification and
increases the life of the LED. The F8-B2may be switched to Silent mode which
disables the fan operation and decreases the output to operate within the
temperature specification. This mode is for customers who are concerned with the
minimal amount of fan noise the F8-B2emits in Boost mode. The current mode
of the F8-B2will be shown briefly on the display before switching to the intensity
level when the fixture is powered on. The mode is also displayed briefly anytime the
dimmer knob is turned for intensity adjustment.

Focus Adjustment
The focus knob contains a passive braking system that allows the bellows to stay
in place when the light is in a downward position. For this system to work properly,
there will be a small amount of rotational movement that engages and disengages
the brake at the focus knob without moving the bellows. This is normal operation. The
center screw that holds the focus knob in place should not be overtightened or the
braking system will not work properly.
Turn the focus knob on the back of the unit to change the output between spot and
flood. At flood position the lens housing will automatically extend approximately 1”
[25mm]. Compress the lens housing below this level by hand for packing & transport
only. CAUTION: Do not move the lens housing by hand between the flood & spot
positions. Do not force the focus knob past its end stops.

F8 Fresnel Zylink Wireless Control
The F8 has built-in wireless control for adjustment up to 50’ (15m) away using the
Zylight Remote or other Zylight instrument (available separately).
ZyLink Operation: To enable ZyLink control, push & quickly release the Mode
knob, then turn the knob to select the desired wireless channel (1-10). A wireless
symbol will appear in the display when ZyLink is enabled. To disable ZyLink turn the
knob until the display shows OFF.
NOTE: DMX control and ZyLink can not be enabled at the same time.
About DMX
DMX is a language allowing all makes and models of different manufactures fixtures
to be linked together and operate from a single controller, as long as all fixtures and
the controller are DMX compliant. A DMX controller sends DMX data instructions
from the controller to the instrument. DMX is the control data from the DMX controller
sent via 5 pin DMX cable to a single fixture, multiple lighting fixtures or instruments
utilizing the DMX Data IN and DMX Data OUT jacks located on all DMX enabled
instruments.
To ensure proper DMX data transmission, when using several DMX fixtures, try to
use the shortest cable path possible. The order in which fixtures are connected in
a DMX line does not influence the DMX channel addressing. For example; a fixture
assigned to a DMX address of 1 may be placed anywhere in a DMX line, at the
beginning, at the end, or anywhere in the middle. When a fixture is assigned a DMX
address of 1, it will “listen” for any DATA command sent by the DMX controller to
channel 1 and respond accordingly no matter where it is located in the DMX chain.

DMX Control
Operating the F8 LED Fresnel from a DMX controller gives users the option to create
unique lighting looks. The F8 has a single 5-pin DMX Breakout Jack on the rear of
the light to link DMX connections between lights when used in a DMX chain. The use
of a DMX Interface Box (P/N 26-02019) is necessary to integrate the F8 into DMX
chain installations by providing connections for looping through both DMX IN and
DMX OUT data.
The F8 DMX Interface Box plugs directly into the 5-pin DMX Breakout jack built in
to the rear of the F8. If the F8 will be the last light in your DMX chain, you may
plug a 5-pin XLR DMX cable directly into the 5-pin DMX Breakout Jack. The F8 is a
self- terminated device and the use of a DMX terminator or Zylight DMX interface box
will not be necessary when the F8 is the last light in your DMX chain, or if you are
running separate lines to each of your fixtures.
When connecting from fixture to fixture, use of the DMX Interface Box is necessary
for correct DMX connections. Not following these steps for DMX connection can
result in erratic behavior. The DMX Interface Box mounts to the bottom of either side
of the F8 yoke. (see image below)
