RAY is a high-performance lighting system.
Do not touch while in operation.
PLEASE RECYCLE ALL
PACKAGING MATERIAL
IMPORTANT SAFETY PRECAUTIONS
•The system should only be cleaned as directed in the Fluence’s Fixture
Cleaning Recommendations which can be downloaded from the Fluence
Support Center www.fluence.science/support-center/.
• 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.
CULTIVATION 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.
For cultivation recommendations visit
www.fluence.science/science-articles/.
GENERAL CARE
RAY Series systems is passively cooled with zero moving components.
They are designed for accepted horticulture 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 console and the roof of your grow area. Failure to do so 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.

CAUTIONS & WARNINGS
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.
