3. Setup and Installation
The Sunlite MH400/U/MOG M59 lamp features an E39 Mogul Base and is designed for use in compatible fixtures. Verify your fixture's requirements before installation.
- Power Disconnection: Ensure the power supply to the fixture is completely turned off at the circuit breaker before beginning installation.
- Lamp Inspection: Carefully remove the new lamp from its packaging. Inspect the lamp for any visible damage, such as cracks or loose components. Do not install a damaged lamp.
- Base Type Verification: Confirm that your fixture requires an E39 Mogul Base. This lamp is not compatible with E17 or E26 bases.
- Installation: Gently screw the E39 Mogul Base of the lamp into the fixture's socket until it is finger-tight. Do not overtighten. Avoid touching the glass envelope with bare hands; use a clean cloth or gloves if necessary.
- Ballast Compatibility: This metal halide bulb is specifically designed for use in M59 ANSI code ballast fixtures. Confirm your fixture's ballast type matches this requirement.
- Power Restoration: Once the lamp is securely installed, restore power to the fixture.

4. Operating Instructions
Upon initial power-up, metal halide lamps require a warm-up period to reach full brightness and stable color. This lamp produces a cool white light at 4000K with a brightness of 36,000 lumens.
- Warm-up Time: The lamp will take approximately 2-5 minutes to reach full brightness and color stability after being turned on.
- Restrike Time: If the lamp is turned off, it requires a cool-down period (typically 5-15 minutes) before it can be reignited. Attempting to restrike a hot lamp too soon may prevent it from lighting or reduce its lifespan.
- Operating Position: This lamp is universal operating position (U) rated, meaning it can be operated in any orientation.

5. Maintenance
Regular maintenance ensures optimal performance and extends the life of your metal halide lamp.
- Cleaning: Periodically clean the outer glass envelope of the lamp and the fixture reflector with a soft, dry cloth when the lamp is cool and power is disconnected. Dust and debris can reduce light output.
- Replacement: The average lifespan of this lamp is 12,000 hours. Replace the lamp when it reaches the end of its rated life or if it shows signs of dimming, flickering, or failure to ignite consistently.
- Disposal: Metal halide lamps contain small amounts of mercury and other materials. Dispose of spent lamps according to local environmental regulations. Many municipalities offer recycling programs for HID lamps.
