The Iluminar 1000W DE CMH Fixture is a high-performance lighting solution designed for professional growing environments. This guide provides essential information for safe installation and operation. Always have a licensed electrician install the fixture to ensure compliance with local electrical codes.

Safety Warnings
- Electrical Safety: Do not open the ballast case. Do not submerge in water. Do not plug into untested or unidentified voltage.
- Handling: Always wear soft cotton or surgical gloves when handling the lamp to prevent oil transfer from skin to the glass.
- Maintenance: Disconnect power before moving the unit or changing the lamp. Allow the lamp to cool for at least 1 hour before touching or attempting a hot restrike.
- Installation: Do not support the ballast by the power cord. Ensure the fixture is hung completely level to prevent lamp failure.
- Interference: Keep away from devices that transmit radio signals (mobile devices, walkie-talkies, microwaves) to avoid interference.
Installation Procedure



- Find a suitable location with sufficient cooling, away from heat sources.
- Use the included hanging cables to suspend the fixture. Ensure it is completely level to the ground.
- Install the lamp into the roll-lock socket using gloves.
- Plug the power cord into the power source.
- For proper lamp break-in, run the fixture at 100% power for at least 100 hours after initial startup.
Operation and Dimming
The fixture features a dimming dial to cycle through output levels. If the lamp fails to start, do not cycle the power on and off repeatedly. If the lamp does not light after 30 minutes, shut off power, wait, and reconnect. The ballast dims or raises output gradually to protect the lamp, so changes may not be instantaneous.

Troubleshooting
If you encounter issues, check the following:
- Lamp not starting: Ensure the lamp is fully inserted and locked. Verify correct input voltage.

- Lamp Damage: Inspect for broken tubes or loose metal. Replace if damaged.
Practical help
Common problems
Ensure the lamp is fully inserted and locked. Verify correct input voltage. If it fails to light after 30 minutes, shut off power, wait, and reconnect.
Move radio-transmitting devices (mobile phones, walkie-talkies, microwaves) away from the fixture.
Inspect for broken tubes or loose internal connections. Replace the lamp immediately if damaged.
Before use
- Ensure the electrical panel supports the load (panels should only support 80% of capacity).
- Wear soft cotton or surgical gloves when handling the lamp.
- Ensure the fixture is hung completely level.
- Verify the input voltage matches the ballast rating.
- Allow the lamp to cool for 1 hour before attempting a hot restrike.
