1. Introduction
This manual provides essential information for the safe and effective use of your VIVOSUN 400 Watt High Pressure Sodium (HPS) Grow Light Bulb. Please read these instructions thoroughly before installation and operation to ensure proper function and longevity of the product.
2. Safety Information
- Electrical Safety: Always disconnect power before installing, removing, or handling the bulb. Ensure all electrical connections are secure and comply with local electrical codes.
- Heat Warning: HPS bulbs generate significant heat. Do not touch the bulb with bare hands during or immediately after operation. Allow sufficient cooling time. Ensure adequate ventilation around the fixture.
- Eye Protection: The intense light emitted by HPS bulbs can be harmful to eyes. Always wear appropriate eye protection when working near an operating HPS light.
- Proper Handling: Handle the bulb by its base, not the glass. Avoid dropping or subjecting the bulb to impact.
- Compatibility: Use only with compatible 400W electronic or magnetic ballasts. Using an incompatible ballast can damage the bulb and pose a safety risk.
- Disposal: Dispose of used bulbs according to local regulations, as they may contain hazardous materials.

- PAR Value: High Photosynthetic Active Radiation (PAR) to stimulate flower growth and enhance fruiting.
- Base Type: E39 base.
- Lumen Maintenance: Maintains over 90% of initial lumen output after 5,000 hours of operation.
- Lifespan: Rated for 24,000 hours.
4. Setup
4.1. Unpacking
Carefully remove the bulb from its packaging. Inspect for any visible damage. Do not use if the bulb appears cracked or broken.
4.2. Installation
- Ensure the power to the grow light fixture is turned off at the main switch.
- Handle the bulb by its ceramic base, avoiding contact with the glass envelope.
- Screw the E39 base of the HPS bulb into the compatible socket of your grow light reflector. Ensure it is securely tightened but do not overtighten.
- Verify that the bulb is properly seated in the socket.
- Connect the grow light fixture to a compatible 400W electronic or magnetic ballast.
5. Operating Instructions
5.1. Initial Startup
After installation, turn on the power. The bulb requires approximately 2-3 minutes to reach full brightness. During this warm-up period, the light intensity and color may fluctuate.
5.2. Re-strike Time
If the bulb is turned off, allow at least 5 minutes before attempting to re-strike it. Attempting to re-strike a hot HPS bulb too quickly can reduce its lifespan or prevent it from igniting.
5.3. Light Spectrum
The VIVOSUN 400W HPS bulb produces a red and orange spectrum light, which is ideal for stimulating flowering and fruiting stages of plant growth.
6. Maintenance
6.1. Cleaning
Ensure the bulb is cool and power is disconnected before cleaning. Gently wipe the glass envelope with a soft, dry cloth to remove dust or debris. Do not use abrasive cleaners or liquids directly on the bulb.
6.2. Lumen Depreciation
Over time, all HPS bulbs experience a gradual decrease in light output (lumen depreciation). This VIVOSUN bulb is designed to maintain over 90% of its initial lumen output after 5,000 hours of operation. For optimal plant growth, consider replacing the bulb after approximately 12-18 months of continuous use, even if it still lights up.
6.3. Lamp Mortality
The bulb has a rated lifetime of 24,000 hours. While designed for durability, factors such as frequent on/off cycles, improper voltage, or physical shock can affect its lifespan.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Bulb does not light up | No power, incorrect wiring, faulty ballast, loose connection, damaged bulb. | Check power supply. Verify all wiring and connections. Ensure ballast is compatible and functional. Re-seat the bulb. Replace bulb if damaged. |
| Bulb flickers or cycles on/off | Aging bulb, improper voltage, faulty ballast, overheating. | Replace bulb if it's near end of life. Check voltage supply. Inspect ballast. Ensure adequate ventilation to prevent overheating. |
| Reduced light output | Lumen depreciation (normal aging), dirty bulb, incorrect ballast. | Clean bulb surface. Consider replacing bulb if it has exceeded its optimal operational hours. Verify ballast compatibility. |
| Bulb takes too long to start | Aging bulb, low voltage, faulty ignitor in ballast. | Replace bulb. Check power supply. Consult ballast manual for ignitor issues. |
