IMPORTANT SAFETY PRECAUTIONS
AND EXPLANATION OF SYMBOLS
• Please read this manual thoroughly before attempting to install or
operate any Fluence RAY Series system.
• After successful installation and configuration of the system, be sure to
retain this manual in a safe place for future reference. Safety is a key
component to a long lasting and trouble free installation.
• It is important you read, fully understand, and observe the subsequent
safety precautions. If you are not comfortable with the installation of
high performance lighting systems, you should seek the services of a
qualified installation professional or call us for help.
• NOTICE: RAY is a high-performance lighting system. Do not touch
while in operation.
• Connect the system only to the power sources of the appropriate
voltage using the AC plug type received. Protect power cables from
being pinched, walked on, or otherwise damaged. Be especially
careful where the power cable enters the power outlet and the unit.
Only connect the system to an electrical outlet or extension cord of
appropriate type and rating. Connect the system only to the power
sources of the correct voltage using the plug received.

• DO NOT defeat the safety purpose of a grounding or polarized plug by
removing ground pins or using unsafe adapters. A polarized plug has two
blades –one wider than the other. A grounding plug has a third ground prong
in addition to the two main conductors. The wide blade or third grounding
prong is provided for your safety. If the provided plug does not fit your outlet,
consult an electrician to replace your obsolete outlet. If you replace the
power cord, only use one of similar type and equal or greater current rating.
• The system should only be cleaned as directed in the manual. You should
seek service for your system by qualified service personnel if any of the
following occur:
1. The power-supply cord or the plug has been damaged.
2. The unit has been exposed to rain.
3. The unit exhibits a marked change in performance.
4. The unit has been dropped, or its enclosure or chassis is damaged.
BEST PRACTICES
Fluence encourages everyone to experiment and pursue their own
techniques. Every crop is different and everyone has different goals.
However, our internal research has given us insight into several strategies
we would like to share.
• Regularly check your plants’ growth and health. Fluence lighting systems
deliver high levels of PAR, typically more than experienced in nature.
Adjustments to H2O, CO2, RH, nutrients, and temperature are typically required.
• Mount the fixture at least 6” from the top of your canopy to ensure
optimal uniformity and consistent PPFD. The RAY Series was designed to
provide uniform light dispersion and requires precise deployment. A 1”
variation in either direction will have a significant change in uniformity
and PPFD (which may or may not be desired).
• Many plants prefer higher temperatures when exposed to high PPFD.
Experiment with higher temperatures to achieve higher yields. Canopy
temperature and room ambient temperature often vary. For accurate
results, test at the canopy level to gauge leaf surface temperature.

GENERAL CARE
• RAY Series systems are passively cooled with zero moving components.
They are designed for harsh environments and years of maintenance-free
performance. Some basic care will keep your system operating at peak
performance cycle-after-cycle.
• Natural convection removes heat away from the heatsink. In order for
the system to properly cool itself, at least one inch of space is required
between the fixture and the surface it is mounted to. Failure to provide
adequate space may shorten the fixture’s lifespan.
• To achieve the optimal lifespan and performance of your fixtures, routinely
check for and remove excess dust, debris, and mineral build up from
heatsink and LED array. Cleaning should always be done with the fixture
unplugged from its power source using low-pressure compressed air or
water to rinse away dirt from light bars.
• Never use a cloth to clean the diode array. Doing so can scratch or
compromise the integrity of the silicon seal, or dislodge diodes entirely.
• To limit degradation, avoid touching the diodes with your hands, even in a
powered off state.

Take caution when
handling RAY fixtures.
Ensure the LED array does
not come in contact with
sharp objects or force that
may damage the diodes.
ASSEMBLY INSTRUCTIONS
Unbox RAY fixture and place on flush, stable surface.
To mount fixture, refer to the instructions included in the
hanging kit package with the associated accessories.
Hang the fixture in the desired location and adjust the
mounting height to at least 6” above the plant canopy.
Connect fixture to power supply using the 8’ DC cable
attached to the RAY fixture.
Mount the power supply to a wall or suitable support
structure using 4mm/#8 fasteners (not included) through
the mounting flange on the sides of the power supply.
Attach 6’ (or 15’) AC cable to power supply AC connector.
Finally, insert AC plug into wall outlet.
If connecting RAY to a dimming system or controller, remove
dust cap and connect to the 3-pin waterproof dimming
connector or the included pigtail dimming adapter.
Note, leave dust cap attached to connector
when not dimming fixture.

WARNING
Risk of electrical shock.
To reduce the possibility
of serious injury,
always take the proper
precautions and unplug
the fixture before moving
or cleaning.
WARNING
Fixture and power supply are UL 1598 Damp
Location rated and are not designed to be
submerged in water. In the event that the
module or power supply enclosure becomes
submersed, first disengage the circuit breaker,
then unplug submersed components before
proceeding to remove from water.
CAUTION
To prevent eye damage,
avoid looking directly at
the unshielded LEDs.
CAUTION
LED and heatsink
surfaces may be hot.
Allow sufficient cooling
time before handling.
CAUTION
To reduce the risk of
overheating or fire, never
place operating fixtures
face down on
a flush surface. Always
allow for adequate
ventilation of fixtures
and power supplies.
ETL Rating: RAY fixtures are rated suitable for damp locations. A “damp location” is defined as an interior or exterior location in which
water or other liquids may drip, splash or flow on or against the electrical components of a lighting fixture or ceiling fan. RAY22, RAY44
& RAY66 are certified to meet UL standards (ETL) from the Intertek safety consulting and certification company and are cETL listed.
1 PPF calculations compiled using integrating sphere measurements and typical spectroadiometric data for each LED to determine typical fixture performance. Actual photometric results may vary
within the LED manufacturer’s bin tolerance.
2 Wattage values are typical expected values. Fluence maintains a tolerance of ±10% on flux and power specifications. Target light levels can vary from projected levels depending on ambient
temperature, room reflections values and dirt accumulation.
CHEMICAL EXPOSURE PRECAUTION
Fluence lighting systems are designed to be resilient against crop protection products. Many chemicals used in the Commercial Horticultural Industry are
corrosive to electronic equipment. Care should be taken to ensure that only approved crop protection products, cleaning agents and/or other chemicals (e.g.,
pesticides, fungicides and insecticides) may come in contact with the luminaire. If the luminaire is accidentally exposed to a corrosive liquid or vapor (e.g.
VOC –Volatile Organic Compound and H2S – Hydrogen Sulfide) the luminaire must be rinsed with clean water as soon as possible. The product warranty will no
longer” apply if the product is repeatedly exposed or remains in the corrosive environment for a prolonged period. It is recommended the luminaires be removed
and protected from the corrosive environment during all periods of aggressive disinfection or sanitization of the facility. The product warranty will be void if the
product is repeatedly exposed to Sulfur.
