2. Safety Information
Always observe the following safety precautions to prevent personal injury or damage to the product.
- Electrical Hazard: Ensure power is disconnected at the circuit breaker or fuse box before installing, removing, or servicing the lamp.
- Hot Surface: Metal halide lamps operate at high temperatures. Allow the lamp and fixture to cool completely before handling. Avoid touching the lamp with bare hands, as oils can cause hot spots and reduce lamp life. Use a clean cloth or gloves.
- Lamp Rupture: HID lamps operate under high pressure and can rupture if mishandled, dropped, or operated in damaged fixtures. Always wear appropriate eye protection and gloves during installation and removal.
- UV Radiation: This lamp is designed with a UV-blocking outer envelope. However, prolonged exposure to any light source can be harmful.
- Ballast Compatibility: Use only with appropriate electronic or magnetic ballasts designed for 35W ceramic metal halide lamps with a G12 base. Using an incompatible ballast can lead to lamp failure, fire, or electric shock.
- Fixture Compatibility: Ensure the fixture is rated for the lamp's wattage and operating temperature. The fixture must be enclosed if specified by the lamp or fixture manufacturer.
- Disposal: Dispose of spent lamps according to local regulations. Metal halide lamps contain small amounts of mercury.
3. Installation
Follow these steps for proper installation of the Philips MasterColor CDM35/T6/830 bulb.
- Power Disconnection: Turn off the power supply to the fixture at the main circuit breaker.
- Cool Down: If replacing an existing lamp, allow the old lamp and fixture to cool down completely before handling.
- Inspect Fixture: Check the lamp holder (G12 base) for any signs of damage or corrosion. Ensure it is clean and dry.
- Handle with Care: Remove the new lamp from its packaging. Hold the lamp by its ceramic base, avoiding contact with the glass envelope. If the glass is touched, clean it with a lint-free cloth moistened with alcohol.
- Insert Lamp: Align the two pins of the G12 base with the corresponding slots in the lamp holder. Gently push the lamp into the holder until it is fully seated. Do not force the lamp.
- Secure Lamp: Ensure the lamp is securely seated in the fixture. Some fixtures may have a locking mechanism.
- Restore Power: Once the lamp is securely installed, restore power to the fixture.
Note: This lamp requires a compatible ballast for operation. Ensure your lighting fixture is equipped with the correct ballast for a 35W ceramic metal halide lamp.
4. Operation
Understanding the operational characteristics of your metal halide bulb.
- Warm-up Time: Metal halide lamps require a warm-up period to reach full brightness and stable color. This typically takes 2-5 minutes from a cold start. During this time, the light output and color temperature will gradually increase.
- Restrike Time: If the lamp is turned off, it cannot be immediately restarted. It requires a cool-down period (restrike time) of typically 5-15 minutes before it can be reignited. Attempting to restart too soon will prevent ignition.
- Color Consistency: Philips MasterColor lamps are known for their excellent color stability over life. However, slight color variations between individual lamps or over time are normal for HID technology.
- Universal Burn Position: This lamp is designed for universal burn position, meaning it can be operated in any orientation without affecting performance or life.
5. Maintenance
Proper maintenance ensures optimal performance and extends the life of your bulb.
- Cleaning: Periodically clean the outer glass envelope of the lamp and the fixture reflector with a soft, dry, lint-free cloth. Ensure the power is off and the lamp is cool before cleaning. Do not use abrasive cleaners or solvents.
- Replacement: Replace the lamp when it reaches its end of life, indicated by flickering, dimming, or failure to ignite. It is recommended to replace lamps in groups in critical applications to maintain consistent light levels and color.
- Fixture Inspection: Regularly inspect the fixture for any signs of wear, damage, or loose connections. Address any issues promptly.
