Installing the fixture
Warning! Mount the system to something that can hold the weight of the LED fixture.
Ensure all light bars are installed correctly and are secure. Carefully turn the fixture over and attach the
metal cable hangers to the mounting hooks. Hang the fixture in required position and height.
Position fixture 50cm – 1m above plant canopy. Ensure the fixture is hung horizontally.
For shorter hanging heights (50cm) from plant canopy and a 1.5m2 footprint; supplemental carbon dioxide
(CO
2
) is recommended so that the plants can photosynthesize the very high level PPFD produced at this height.
For PPFD over 1000µmol/s/m2 up to max 1500µmol/s/m2 supplemental CO
2
at a 1:1 ratio is recommended. i.e. at
1500µmol/s/m^2 PPFD supplemental CO
2
at 1500ppm is advised.
Warning! Exposing crops to ultra high PPFD without supplemental CO
2
can be detrimental to plant growth.
The LED fixture can be used without supplemental CO
2
at greater hanging heights (1m+) as this will decrease
PPFD and will increase light footprint to 1.8m2.
Individual 100W light bars are available to purchase as replacements or with different spectral ratios to adjust
fixture spectral output.
The LED fixture’s modular design uses an intelligent LED driver which can decrease or increase power to match
the amount of 100W light bars installed on the fixture automatically. If not all light bars are required, the driver
will only draw power required for the amount of light bars connected eg if six light bars are connected the
driver will only draw 600W to power them.
Warning! At least one light bar must be installed in the fixture before switching on.
Connect & disconnect the driver
The LED driver is fixed to the mounting bracket with four retention screws through bracket into driver base plate.
For greater flexibility the driver can be disconnected from the fixture and used remotely using Lumatek 5m LED
driver extension cables (sold separately).
To connect driver output and dimming to fixture; ensure the power and dimming self-locking male connectors
are correctly aligned with corresponding female connectors on driver and push together until click-locked.
To disconnect; turn male connector anti-clockwise to unlock and pull apart from female.
