SAFETY INFORMATION

Dear Users

Thank you for choosing our products! Please read this instruction carefully before using your lights.

CAUTION: Do not look directly at the LED bulbs when the lighting equipment is working.

The maximum temperature of the installed environment (ambient temperature) will ensure the safe operation of the lighting equipment. So you will need to control the temperature within the installed environment. (Example: mechanical ventilation or cooling system is required to maintain the temperature within the growing space below 104°F (or 40°C) when the lighting equipment is in operation).

Instructions to guide the installation such that cords

Are not concealed or extended through a wall, floor, ceiling, or other parts of the building structure,
Are not located above a suspended ceiling or dropped ceiling,
Are not permanently affixed to the building structure,
Are routed so that they are not subject to strain and are protected from physical damage,
Are visible over their entire length, and
Are used within their rated ampacity as determined for the maximum temperature of the installed environment specified in the instructions.

This lighting equipment is for indoor use only. Not water-proof, protect your lighting equipment from dampness, dust, and water.
CAUTION: For horticultural lighting structures, installation shall be performed by qualified personnel and that the structures are intended for installation subject to approval by the authority having jurisdiction.
Set up your light in the operating environment that allows for adequate air circulation. Never push objects into the ventilation openings.
When cleaning the outside of your light and its components, first, you need to shut off your light, then unplug the power cord. Using a clean, soft, lint-free cloth to wipe the light. Avoid getting moisture in any openings.
CAUTION: Possibly hazardous optical radiation is emitted from this product. Do not stare at the operating lamp. May be harmful to the eyes.

Seedlings: You will need to hang the light high due to the delicate nature of seedlings. We recommend a break-in period of about a week while a seed has broken the surface. The first set of real leaves should be present while the seedling has been above ground for about a week.
Clones: Clones are a little bit hardier than fresh seedlings, but still, need to be given gentle light as they are entirely rootless when first cut, and need to conserve energy and moisture to transition into a rooting stage.
Vegetative: The deeper red spectrum is utilized less by the plant than when it is in flower. It uses high levels of white light that are essential for creating lush, thick plants that have tight internodal spacing and minimal stretching.
Flowering: The plant has much work to do and is performing many complex biological processes in producing flowers and fruits. Because of this, the plant now requires large amounts of light.
Late Flower: Most rapid development has stopped, and the plant is gearing up for the scene in which the large flowers and fruits will mature or ripen.

If you expose plants to high light intensities too early in the crop cycle, you can damage chlorophyll pigments causing photo-oxidation (photo-bleaching), so we recommend slowly increasing your light intensity as your plant develops.

MOUNTING INSTRUCTIONS
