1. Introduction
The PHOTONTEK XT 1000W CO2 Pro LED is a high-performance grow light designed for professional indoor cultivation. This fixture delivers a balanced, full-spectrum light with high Photosynthetic Photon Flux Density (PPFD) levels, optimized for plant growth cycles. It is engineered for use in 5'x5' coverage areas, particularly when supplemented with CO2, but can also be adapted for 6'x6' areas without CO2 supplementation. This manual provides essential information for the safe and effective installation, operation, and maintenance of your PHOTONTEK XT 1000W CO2 Pro LED grow light.
2. Safety Information

4. Setup and Installation
4.1 Unpacking and Inspection
- Carefully remove all components from the packaging.
- Inspect the fixture for any signs of damage during transit. Contact your supplier immediately if any damage is found.
- Ensure all listed components in "What's in the Box" are present.
4.2 Mounting the Fixture
The PHOTONTEK XT 1000W CO2 Pro LED is designed to be suspended above your plant canopy.
- Identify a sturdy overhead structure capable of supporting the weight of the fixture (approximately 39.7 pounds or 17.999 kg).
- Attach the provided hanging cables or ratchets to the designated hanging points on the fixture.
- Securely attach the other end of the hanging system to your overhead structure.
- Adjust the hanging height to achieve the desired distance from the plant canopy. Refer to the "Operating Instructions" section for recommended hanging heights based on CO2 usage.

4.3 Electrical Connection
Ensure the power source matches the voltage requirements of the fixture (277 Volts AC).
- Connect the power cord to the input port on the fixture's driver box. Ensure a secure connection.
- Plug the other end of the power cord into a grounded electrical outlet.
- If using a dimmer or external controller (Control Method: App, Switch Style: Dimmer, Push Button), connect it according to its specific instructions to the designated dimming ports on the fixture.

5. Operating Instructions
5.1 Powering On/Off
Once the fixture is securely mounted and connected to power, it can be turned on.
- To power on, ensure the power cord is plugged into a live outlet. If using a timer, set the desired light cycle.
- To power off, disconnect the power cord from the outlet or use a connected timer/controller.
5.2 Light Intensity and Spectrum
The PHOTONTEK XT 1000W CO2 Pro LED provides a full spectrum light. The intensity can be adjusted using the integrated dimmer or an external app/controller.
- Dimmer Control: Use the push-button dimmer switch (if present) or the app control to adjust light output from 0-100%.
- Recommended PPFD Levels:
- For 5'x5' coverage with CO2 supplementation: Aim for PPFD levels up to 1500 µmol/s/m². Maintain CO2 levels up to 1500 PPM, matching PPFD levels 1:1 once exceeding 1000 µmol/s/m².
- For 6'x6' coverage without CO2 supplementation: Increase the distance between the fixture and the plant canopy to achieve optimal PPFD levels for the specific growth stage. This will result in lower overall PPFD intensity compared to CO2-supplemented setups.
