OPERATIONAL GUIDELINES
• Mount light bars approximately 6” above the top of the plant canopy. This assures
that the maximum amount of light energy reaches and penetrates the plant canopy.
Light diminishes significantly as it is pulled away from the plant canopy.
• Raise the fixture as the plant canopy height increases
• Many plants prefer increased temperatures when exposed to high amounts of light
energy. Therefore, it is encouraged to experiment with increased temperature.
• Regularly check plant growth and health. Consider adjusting water, CO2, relative
humidity, nutrients, and ambient temperature.
CARE
The SQRT670CX has been designed for harsh environments and years of
maintenance-free operation. Please maintain your fixture to assure peak operation:
• Assure proper air flow around the fixture, maintaining at least 1” of space between
top of fixture (spine) and the mounting surface or ceiling.
• Remove excess dust, debris and mineral build-up from light bars and spine. Clean
while fixture is unplugged. Use low-pressure air or a rag dampened with water.
• Do not touch the LED array with hands.
