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
Setup instructions
The ARAY 120W will rotate in the grow area on its single hanger
It’s ok : )
The light spread is even at any angle of rotation
Dimmer adjustment
Adjust the Light intensity using the dimmer control on the LED driver
From seedling:
For Seedlings start at a 1/5 turn of the dimmer from off position (about 30W output) – keep at this level for the first 2 to 3 weeks until two or three sets of true leaves have developed.
Adjust upwards at 1/5 turn every few days up to 100% for flowering
Plants over three weeks old:
Hang at 16cm or 6″ over the top of the plant canopy. Set the dimmer to 100%
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.

How much light plants need for maximum yield
To optimise your grow it is recommended that your plants receive 500-1,000 μmols of PAR light for every m² (PPFD). Less than this and growth rates and yield will be low.
Growth rates at higher PPFD levels do not justify the extra energy cost and heat output and the plants require additional CO₂ to utilise the high PAR intensity

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. They 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 circuits
In the event of any of the above the driver will shut down. The driver will automatically restart if the conditions return to normal.
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
