The TSL ROI-E720 Series LED System is a high-performance and cost-effective horticultural lighting solution designed for commercial horticulture. This LED system is the result of a collaboration between TSL Horti Tech and Grower's Choice, combining their extensive experience in the horticulture lighting industry. The ROI-E720 is engineered to provide optimal light for plant growth, ensuring efficiency and uniformity across the canopy.

Function Description:

The primary function of the ROI-E720 Series LED System is to provide artificial light for plant cultivation in commercial horticulture settings. It is designed to deliver a full-phase spectrum, which means it emits light across the entire photosynthetic active radiation (PAR) range, supporting plants through all stages of growth, from vegetative to flowering. The system utilizes LED technology, known for its energy efficiency and long lifespan compared to traditional lighting methods. The design incorporates multiple light bars, which helps in achieving an even distribution of light over the plant canopy, minimizing hot spots and ensuring consistent growth. The fixture is passively cooled, meaning it does not rely on moving components like fans for heat dissipation. This design choice contributes to its silent operation and potentially longer lifespan due to fewer mechanical parts that can fail. The ROI-E720 also features dimming capabilities, allowing users to adjust the light intensity to suit specific plant needs or growth stages, thereby optimizing energy consumption and plant health.

Usage Features:

The ROI-E720 LED system is designed for straightforward installation and operation in various grow environments. Before installation, users are advised to read the provided instructions thoroughly to ensure proper setup and to understand the safety warnings. The fixture is shipped unfolded and needs to be expanded and secured by tightening a nut to lock its position. It is crucial to handle the fixture by its primary structure and not by the LED bars themselves to prevent damage.

Mounting the ROI-E720 is flexible, as it can be suspended from a supporting structure or frame using carabiner cables or other suspension means through its four mounting rings. The recommended mounting height is at least 6 inches (15.2 cm) above the plant canopy to ensure optimal light efficiency and uniformity. Adequate ventilation around the fixture is also essential to maintain its performance and prevent overheating. The system includes a rope ratchet kit for convenient height adjustment.

The ROI-E720 is equipped with a power cord (whip) that is internally connected to the fixture, typically with an M25-Nema 6-15P plug. Users need to ensure that a proper mating receptacle is available for connection. The system supports various voltage services, including 120V, 208V, 240V, and 277V, making it adaptable to different electrical setups. An information page, 120/240 adaptor, and a 1ft NEMA 6-15P 240V - M25 Plug are included to facilitate connection.

For advanced control, the ROI-E720 can be integrated with a lighting controller (not included), which allows for precise dimming (0-10V) and potentially other automated functions. RJ data cables (not included) would be used for this connection. This external control capability enables growers to fine-tune light schedules and intensity, further optimizing plant growth and energy usage. The system is designed for damp locations, indicating its suitability for environments with higher humidity levels common in horticulture.

Maintenance Features:

Maintaining the ROI-E720 LED system is relatively simple due to its passive cooling design and robust construction. The system is passively cooled, meaning there are no moving components like fans that require regular cleaning or replacement. This design minimizes maintenance needs and contributes to the fixture's reliability. However, it is crucial not to attempt to open or disassemble the fixture, as it contains no user-serviceable parts, and doing so could void the warranty and cause harm.

Before any maintenance or handling, it is imperative to disconnect the fixture from the mains power. This is a critical safety precaution to prevent electrical shock. Users should always allow at least 10 minutes for the fixture to cool down before handling, as the unit can become hot during operation. Protective gloves and glasses are recommended during installation and any handling.

Regular inspection of the power cord for any damage is advised. If the power cord is damaged, the fixture should not be used. Similarly, if the unit has been dropped or its enclosure or bars are damaged, it should not be operated. The LED diodes should not be touched directly.

To ensure optimal performance and prevent overheating, it is important to maintain minimum clearances around the fixture: 2 inches (5 cm) from the ceiling, 2 inches (5 cm) between fixtures, 6 inches (15 cm) from walls, 6 inches (15 cm) from plants, and 6 inches (15 cm) from other objects. The maximum ambient temperature for operation is 0 to 40°C (32 to 104°F). A mechanical ventilation or cooling system may be required to keep the growing space within this temperature range.

The ROI-E720 is splash-proof but not waterproof. In the event of submersion, the circuit breaker should be disengaged, and the fixture unplugged before removal from water. The product is backed by a 5-year standard warranty, covering defects in material and workmanship under normal operating conditions. This warranty provides assurance of the product's quality and durability, with TSL Horti Tech offering repair or replacement for qualifying defects.
