4. Setup Instructions
4.1. Assembling the Grow Light
- Carefully remove all components from the packaging.
- Attach the metal clips from the hanging kit to the designated points on the top corners of the LED grow light fixture.
- Connect the rope hangers to the metal clips.
- Hang the light securely from a sturdy support structure in your grow area using the rope hangers. Ensure the light is level.
4.2. Connecting the Detachable Driver
The TSW2000 features a detachable driver, allowing you to position it outside the grow space to reduce heat buildup inside the tent.
- Locate the external driver and the corresponding connection port on the LED grow light fixture.
- Connect the driver cable to the light fixture. Ensure a secure connection.
- Position the driver outside your grow tent or in a location where heat dissipation is optimal.

4.3. Power Connection
- Connect the power cord to the external driver.
- Plug the power cord into a compatible electrical outlet (100-277VAC).
- The light is now ready for operation.
5. Operating Instructions
5.1. Dimming Operation
The TSW2000 features an independent dimming button and knob on the external driver, allowing precise control over light intensity.
- Dimmer Button: Toggle between DIM (dimmer on) and EXT (dimmer off, for external controller).
- Dimmer Knob: Adjust brightness from 0% (OFF) to 100% (MAX). Turn the knob clockwise to increase brightness and counter-clockwise to decrease.

5.2. Daisy Chain Functionality
The TSW2000 supports daisy chaining, allowing up to 50 LED lights to be connected and controlled from a single dimmer. This is ideal for larger grow operations.
- Ensure all lights are powered off before connecting.
- Connect the output port (CH2) of the first light's driver to the input port (CH1) of the next light's driver using a suitable daisy chain cable (not included).
- Repeat for additional lights, connecting them in sequence.
- The dimmer on the first light will control the intensity of all connected lights.

5.3. Full Spectrum Lighting
The TSW2000 provides a sun-like full spectrum, including 730-740nm Red IR, 3200-4200Knm, and 5200-6800Knm spectra. This optimized spectrum supports rapid plant response from seed to flower, contributing to increased yield and crop quality.

5.4. Recommended Hanging Height and Dimmer Settings
Adjust the hanging height and dimmer setting according to your plant's growth stage for optimal results. The recommended footprint for flowering is 3x3ft and for vegetative growth is 4x4ft.
Figure 5.4: Recommended hanging height, dimmer settings, and PPFD intensity for different plant growth stages.
| Stage | Hang Height | Dimmer Setting | Intensity (PPFD) |
|---|---|---|---|
| Seedling/Clone | 12" (30cm) | 25% | 150-350 µmol.m².s¹ |
| Vegetative | 12" (30cm) | 75% | 550-1000 µmol.m².s¹ |
| Flowering | 12" (30cm) | 100% | 700-1300 µmol.m².s¹ |
5.5. Coverage Area
The TSW2000 provides uniform light distribution across its coverage area, ensuring all plants receive adequate light for growth.
- Core Coverage: 3ft x 3ft
- Max Coverage: 4ft x 4ft

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your MARS HYDRO TSW2000 LED Grow Light.
- Cleaning: Periodically wipe the light fixture and reflector with a soft, dry cloth to remove dust and debris. Ensure the light is unplugged before cleaning. Do not use liquid cleaners directly on the LEDs or electrical components.
- Inspection: Regularly check the power cord and connections for any signs of damage or wear. If any damage is found, discontinue use and contact customer support.
- Ventilation: Ensure adequate airflow around the light and its driver to prevent heat buildup.
7. Troubleshooting
If you encounter issues with your TSW2000 LED Grow Light, refer to the following common problems and solutions:
- Light does not turn on:
- Check if the power cord is securely plugged into both the driver and the wall outlet.
- Ensure the wall outlet is functional by testing it with another device.
- Verify that the dimmer knob is not set to OFF (0%).
- If using daisy chain, ensure the main light is powered on and its dimmer is not off.
- Light output is too low/high:
- Adjust the dimmer knob to the desired intensity.
- Ensure the dimmer button is set to DIM if you are using the onboard dimmer.
- Uneven light distribution:
- Ensure the light fixture is hung level and centered over your grow area.
- Adjust the hanging height according to the recommended settings for your plant stage.
If the problem persists after attempting these solutions, please contact MARS HYDRO customer support.
