Adjust the Light intensity using the dimmer control on the LED driver
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
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.
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
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.
The LED driver is highly efficient and reliable constant current transformer and has inbuilt protection from:
In the event of any of the above the driver will shut down. The driver will automatically restart if the conditions return to normal.
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.
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.
