- Power Disconnection: Before beginning any installation, ensure the main power supply to the installation area is completely disconnected at the circuit breaker or fuse box. Verify with a voltage tester.
- Mounting: Securely attach the luminaire to the intended pole or mounting surface using appropriate hardware. Ensure the mounting is stable and can support the fixture's weight (approximately 1 kg).

5. Operating Instructions
Once installed, operating the Thorn Europhane NELLA 100W HID SIL is straightforward:
- Power On: Restore power to the circuit at the breaker. The HID lamp will strike and gradually reach full brightness over several minutes.
- Power Off: To turn off the light, disconnect power at the switch or circuit breaker. Note that HID lamps require a cool-down period before they can be re-ignited after being turned off.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your luminaire.
- Cleaning: To clean the luminaire, ensure the power is off and the fixture is cool. Use a soft, damp cloth to wipe down the exterior surfaces. Avoid abrasive cleaners or solvents. For detailed information on cleaning bulbs, refer to general guidelines for HID lamps.
- Lamp Replacement: HID lamps have a finite lifespan. When the lamp reaches its end of life (indicated by flickering, dimming, or failure to ignite), replace it with a new 100W HID lamp with an E27 base. Always disconnect power and allow the fixture to cool before replacing the lamp.
- Inspection: Periodically inspect the fixture for any signs of wear, damage, or loose connections. Address any issues promptly.
- Recycling: HID lamps contain mercury and other materials that require special disposal. Do not dispose of old lamps in household waste. Please refer to local regulations for proper recycling of bulbs. Information on recycling for bulbs is available through local waste management services.
