Setup and Installation
The Hydrofarm Agrobrite T5 system is designed for ease of setup. No complex assembly is required for the fixture itself.
Installation Steps:

- Inspect all included components for any damage, missing parts, or other concerns. Contact your local retailer for replacement or new parts if required.
- If there is a protective film on the reflector surfaces, be sure to remove it completely prior to turning on the system.
- To hang the fixture in the desired position, utilize the appropriate holes and slots with the hanging hooks.
- For overhead hanging, use the holes and slots at the center on each end.
- For vertical hanging, use only one of the hooks with the center end hole and slot set. See Figure 1.

Operating Instructions
The Agrobrite T5 system is designed for straightforward operation. Once installed, simply plug the 8-foot grounded power cord into a suitable electrical outlet. The fixture features a power switch for easy on/off control.
Optimal Use:
- The 6400K T5 tubes provide a balanced daylight spectrum, which is highly effective for the vegetative growth phase of plants.
- The low-profile, open-roof design, combined with the inherently low temperature of T5 bulbs, allows for safe operation even in close quarters.
- The high-output fluorescent tubes offer twice the efficiency and light output compared to common fluorescent bulbs, ensuring robust plant development.
Maintenance
To ensure the longevity and optimal performance of your Hydrofarm Agrobrite FLT28 T5 Grow Light System, follow these general maintenance guidelines:
- Cleaning: Periodically wipe down the exterior of the fixture and the T5 tubes with a soft, dry cloth to remove dust and debris. Ensure the unit is unplugged before cleaning. Avoid using abrasive cleaners or solvents.
- Bulb Replacement: Over time, the light output of fluorescent tubes may diminish. Replace T5 tubes as needed to maintain optimal light intensity for your plants. Ensure replacement bulbs match the specified type (T5 6400K).
- Reflector Care: The faceted specular aluminum reflector is crucial for light distribution. Keep it clean and free of obstructions to maximize light reflection.
- Power Cord Inspection: Regularly inspect the power cord for any signs of damage, fraying, or kinks. If damage is found, discontinue use and replace the cord or consult a qualified electrician.
For any internal component issues, such as ballast replacement, it is recommended to consult with a qualified technician or contact Hydrofarm customer support.
