Operating Instructions
After proper installation and power restoration, the lamp will ignite. Metal halide lamps require a warm-up period to reach full brightness and color stability.
- Warm-up Time: The lamp will typically take 2-5 minutes to reach full light output and color.
- 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 reignite a hot lamp too soon may prevent it from starting or reduce its life.
- Normal Operation: Once warmed up, the lamp will provide consistent, bright illumination.
Maintenance
- Cleaning: Ensure power is off and the lamp is cool before cleaning. Gently wipe the outer glass envelope with a clean, dry, lint-free cloth. Do not use abrasive cleaners or liquids directly on the lamp.
- Replacement: Replace the lamp when it reaches its average rated life (7500 hours), shows signs of flickering, or fails to ignite consistently. Always replace with a lamp of the same type and wattage.
- Fixture Inspection: Periodically inspect the fixture, wiring, and ballast for any signs of wear, damage, or corrosion.
