4. Operating Instructions

The OSRAM SYLVANIA ECT (11560) bulb operates like a standard incandescent lamp. Once installed in a compatible fixture and power is supplied, it will illuminate when the fixture's switch is turned on.

• Ensure the fixture is stable and positioned correctly for your lighting needs.
• Avoid frequent on/off cycling, which can reduce bulb lifespan.
• Always allow the bulb to cool down completely before moving the fixture or handling the bulb.

5. Maintenance

• Cleaning: With the power off and the bulb completely cool, gently wipe the glass with a soft, dry, lint-free cloth if dust or smudges accumulate. Do not use liquid cleaners.
• Inspection: Periodically inspect the bulb for any signs of damage or discoloration. If any damage is observed, replace the bulb immediately.
• Replacement: When the bulb reaches the end of its life, follow the "Setup and Installation" steps in reverse to safely remove and replace it.

6. Troubleshooting

If the bulb does not illuminate after installation:

• Check Power: Ensure the fixture is receiving power and the switch is in the "on" position.
• Check Connection: Turn off power, then carefully re-tighten the bulb in the socket to ensure a proper electrical connection.
• Inspect Bulb: With power off and bulb cool, visually inspect the filament. If it appears broken, the bulb needs replacement.
• Check Fixture: Test the fixture with a known working bulb of appropriate wattage and voltage to rule out a fixture issue.
