2. Safety Information

Please read and understand all safety instructions before handling or installing the bulb. Failure to follow these instructions may result in electric shock, fire, or personal injury.

• Electrical Hazard: Always disconnect power to the fixture before installing, removing, or cleaning the bulb.

4. Setup and Installation

Follow these steps to safely install the Rexim halogen bulb:

1. Power Off: Ensure the power supply to the light fixture is completely disconnected at the circuit breaker or wall switch.
2. Cool Down: If replacing an existing bulb, allow the old bulb to cool down completely before touching it.
3. Remove Old Bulb: Carefully grasp the old bulb by its ceramic base (not the glass) and gently pull it straight out from the socket. Avoid twisting if the socket is designed for straight insertion.
4. Prepare New Bulb: Remove the new Rexim bulb from its packaging. Handle the bulb by its ceramic base only. If you accidentally touch the glass envelope, clean it with a lint-free cloth moistened with rubbing alcohol and allow it to dry completely before installation.
5. Insert New Bulb: Align the two pins of the new bulb with the corresponding holes in the fixture's socket. Gently push the bulb straight into the socket until it is fully seated. Do not force the bulb.
6. Secure Fixture: Reassemble any covers or protective elements of the light fixture.
7. Restore Power: Turn the power supply back on.
8. Test: Activate the light fixture to ensure the new bulb is functioning correctly.

5. Operating Instructions

Once properly installed, the Rexim 24V 150W FDS DZE Halogen Bulb operates in conjunction with your compatible dental light or lamp fixture. No special operating procedures are required for the bulb itself beyond the fixture's standard controls.

• Ensure the fixture's power switch is in the 'ON' position to illuminate the bulb.
• The bulb will reach full brightness almost instantly.
• Avoid frequent on/off cycling, as this can reduce the bulb's lifespan.

6. Maintenance

Proper maintenance ensures optimal performance and longevity of your halogen bulb.

• Cleaning: If the glass envelope of the bulb becomes dirty or smudged, turn off the power and allow the bulb to cool. Carefully remove the bulb and clean the glass with a soft, lint-free cloth moistened with rubbing alcohol. Ensure the bulb is completely dry before reinstallation.
• Inspection: Periodically inspect the bulb for any signs of damage, such as cracks in the glass or discoloration. Replace damaged bulbs immediately.
• Fixture Maintenance: Regularly clean the light fixture's reflectors and lenses according to the fixture manufacturer's instructions to maintain light output efficiency.

7. Troubleshooting

If the bulb does not light after installation, consider the following common issues:

• No Power: Check if the power supply to the fixture is on. Verify that the circuit breaker has not tripped.
• Improper Installation: Ensure the bulb is fully and correctly seated in the socket. The pins must make proper contact.
• Incorrect Bulb: Confirm that the installed bulb matches the voltage and wattage requirements of your fixture.
• Blown Bulb: Even new bulbs can sometimes be faulty. If possible, test the bulb in another compatible fixture or try a different new bulb.
• Fixture Fault: If multiple bulbs fail to light, the issue might be with the light fixture itself (e.g., faulty socket, wiring, or transformer). Consult a qualified technician for fixture repair.
