Safety Information
Metal halide lamps operate at high temperatures and pressures. Failure to follow safety precautions can result in personal injury or property damage.
- Risk of Fire: Use only in luminaires designed for 1500W metal halide lamps. Ensure proper ventilation.
- Risk of Electric Shock: Disconnect power before installation, removal, or inspection.
- Risk of Burn: Allow lamp to cool completely before handling.
- Risk of Arc Tube Rupture: This lamp has an unprotected arc tube. It must be used in an enclosed luminaire to prevent injury from hot lamp fragments if the arc tube ruptures.
- Do not operate lamps beyond their rated life.
- Do not use if the outer envelope is broken or scratched.
- Dispose of lamps according to local regulations.
Setup and Installation
- Power Disconnection: Ensure the power supply to the luminaire is completely disconnected before beginning installation.
- Luminaire Compatibility: Verify that the luminaire is rated for a 1500 Watt metal halide lamp and is designed for an E39 Mogul screw base. The luminaire must be enclosed due to the lamp's unprotected arc tube.
- Lamp Inspection: Carefully remove the lamp from its packaging. Inspect the lamp for any signs of damage, such as cracks or scratches on the glass envelope. Do not install a damaged lamp.
- Installation: Hold the lamp by its base, not the glass envelope. Carefully screw the E39 Mogul base into the luminaire socket until it is finger-tight. Do not overtighten.
- Burn Position: This lamp is designed for universal burn position, meaning it can be operated in any orientation.
- Power Connection: Once the lamp is securely installed and the luminaire is properly closed, restore power to the luminaire.
Operating Instructions
- Initial Start-up: Upon first ignition, metal halide lamps require a warm-up period to reach full brightness and stable color. This typically takes several minutes.
- Restrike Time: If the lamp is turned off, it cannot be immediately restarted. A cool-down period (restrike time) of 5-15 minutes is required before the lamp can reignite.
- Operating Environment: Operate the lamp within the temperature and humidity ranges specified by the luminaire manufacturer.
- Intended Use: This lamp is specifically designed for high-intensity discharge applications, such as sports lighting, where its 170,000 lumens and 4000K cool white light are beneficial.
Maintenance
- Cleaning: Ensure power is disconnected and the lamp is cool before cleaning. Wipe the outer glass envelope with a clean, dry, lint-free cloth. Do not use abrasive cleaners or liquids that could damage the lamp or luminaire.
- Lamp Replacement: Replace the lamp when it reaches its rated average life of 3000 hours, or if there is a noticeable decrease in light output, flickering, or failure to ignite. Operating lamps beyond their rated life increases the risk of arc tube rupture.
- Ballast Inspection: Periodically inspect the ballast and wiring for any signs of wear or damage. Consult a qualified electrician for any repairs.
