STOP – Please read all these instructions carefully especially the safety section before unboxing and assembling
Safety
Please read this manual thoroughly before assembling and installing the MIGRO
grow lights system.
Please retain this manual for reference for the lifetime for the product
The MIGRO system limits the voltage in the grow room to 96Vdc and has built in
protection for overcurrent, shorts or overheating. However, to minimise any
remaining risk please switch the power off while installing and adjusting the
MIGRO system. If the mains plug needs to be changed to suit your power socket
only a qualified person should carry out this work, in accordance with your
local codes.
The MIGRO system will operate on a supply voltage ranging from 100V to 277V AC
and from 50 to 60Hz frequency. Any other supply voltage will damage the
lighting system.
The grow light and the cabling from the LED driver to the grow light is IP66
rated and can be used in a wet area. The mains power plug is not IP rated for
a wet area and should be located in a dry area outside of the grow room. If
the cable insulation or glands are damaged switch off the system immediately
and return to us for repair.
The MIGRO grow light has a highly efficient and passive cooling heatsink. In order to function correctly air must be able to flow freely across the fins of the heatsink. Do not cover the grow light and restrict the airflow across the heatsink under any circumstances. This will result in heat build up which may damage the grow light and/or cause a fire. Do not put the grow light down on any surface when the light is on. The light intensity and radiated heat may damage the surface.
The light intensity from each MIGRO grow light is very high. If you look directly at the light source from less than 20cm or 9” away the intensity is equivalent to the sun. To protect your eyes do not look directly at the light source when less than 60cm or 2 feet away.
ARAY 2, 3 & 4 setup instructions
Connect the LED bars together with the connector brackets provided. Centre the bracket along the length of the LED bar (line it up with the Cable gland) and screw in place using the allen key provided. Attach the ratchet hangers to the grow light at the cable splitter splitter.
ARAY 2 & 3
Attach 2 x ratchet hangers to each light fixture
ARAY 4
Attach the 2 x clips to each cable splitter and attach a single ratchet hanger
to each cable
ARAY 4X4 and 5X5
Unfold the grow light carefully and rest on a flat clean surface with the LEDs
facing down.
Attach the hanging clips to each end.
Attach a hanging ratchet to each end and raise the light into position.
LED Driver mounting
Caution : Do not run 2 led bars only from the larger power ARAY 4, 8 & 12
driver.
The LEDs will be overpowered and will be damaged. Only run 4 bars with the
splitter cable.
You can daisy chain the power cable for up to three of the ARAY 3 and ARAY 4
LED drivers. Do not exceed this amount or the power cables will overheat.
Hang the LED driver using the S hook or Carabiner clip. You can also fix the
LED drive to the wall using the fixing points provided.
Dimmer adjustment – ARAY 2,3,4, 4X4 & 5X5
Adjust the Light intensity using the dimmer control on the LED driver. Set the dimmer switch to ON or Local to enable the on board dimmer control. Set the Dimmer switch to Off/Remote to operate from an external dimmer signal.
| Stage | Seedlings | Vegetative | Flowering |
|---|---|---|---|
| Week | 1 to 2 | week 3 to flowering | 12 hour cycle |
| Hanging height | Dimmer setting | Hanging height | Dimmer setting |
| height | Dimmer setting | ||
| ARAY 1 | 14″ or 35cm | 80% | 14″ or 35cm |
| ARAY 2 | 10″ or 25cm | 40% | 8″ or 20cm |
| ARAY 3 | 15″ or 38cm | 40% | 16″ or 40cm |
| ARAY 4 | 14″ or 35cm | 40% | 20″ or 50cm |
| ARAY 4X4 | 12″ or 30cm | 40% | 12″ or 30cm |
| ARAY 5X5 | 12″ or 30cm | 40% | 12″ or 30cm |
After initial setup check them after a few hours. Look for signs of plant stress; curled leave tips, yellowing leaf tips etc. If you see these signs reduce dimmer by 1/5 turn and monitor.

Light Spectrum
Hardware overview
LED bar
The small LEDs (surface mounted diodes, SMDs) are delicate and can be easily
damaged.
Take care putting them down and during assembly.
The LEDs are protected from water and dust with a conformal coating so they
can be wiped clean of dust and dirt.
LED driver
The LED driver is highly efficient and reliable constant current transformer
and has inbuilt protection from:
- Output over voltage
- Over temperature
- Short circuit
- In the event of any of the above the driver will shut down. The driver will automatically restart if the conditions return to normal.
The driver and the mains plug connection should be located outside of the grow
area in a dry and safe position with adequate ventilation.
The life of the LED driver is related to its operating temperature. Keeping it
as cool as possible will extend its life.
The driver is dimmer controlled and has an inbuilt dial for adjusting the
output from 20% to 100%.
Up to 15 drivers can be connected together in daisy chain connection for
simultaneous dimming control.
Set the toggle switch on for master dimmer driver and off for slave dimmer
drivers. Airflow and ventilation
Whatever position the grow light is fixed always ensure there is adequate room
for airflow around the heatsink to prevent heat buildup. There should be at
least 5cm or 2” clearance on three sides of the heatsink.
The heatsink is a ‘fast flow’ passive heatsink allowing air to move quickly
over the heatsink surface and remove the heat at a high rate.
Driver and Lamp operating temperature
Both the led bar heatsink and led driver both operate at about 25 deg. C or 45
F above ambient temperature. So at 25 degrees C or 77 F room temp the driver
and heatsink will be about 50 deg. C or 122 F. This is perfectly normal and
safe.
To minimise the temperature locate the driver down low at the air intake and
have the out take moving air across the heatsink.
If the driver case temperature gets to 90 DegC or 195 F the output current
will be reduced. If the temperature does not reduce then it powers off until
temperatures have reduced.
Maintenance
The MIGRO grow light system requires almost no maintenance. In ordinary use
the only maintenance required is to keep the heatsink and the led surface
clean. This will ensure the cooling performance and light output are
maintained, respectively.
To clean all of the components switch off the power and use warm water and
soap with a damp cloth. Do not under any circumstances use a solvent, acid
based or an abrasive cleaner on any of the components. Doing so may damage the
finish of the product and
the electrical and led coating.
