This 9-watt, 120-volt bulb features a 2-pin (G23) base and emits a 4,100K cool white light. Please read these instructions thoroughly before installation and operation.
2. Safety Information
Observe the following safety precautions to prevent injury or damage:
- Power Disconnection: Always ensure the power supply to the fixture is turned off at the circuit breaker or fuse box before installing, removing, or handling the bulb.
- Correct Fixture: Use this bulb only in fixtures designed for 2-pin (G23) compact fluorescent lamps with the correct wattage and voltage ratings.
- Handling: Handle the bulb by its plastic base, not the glass tubes, to avoid breakage and contamination.
- Breakage: In case of bulb breakage, ventilate the area and carefully clean up glass fragments and mercury residue according to local regulations. Avoid direct contact with broken glass.
- Disposal: Fluorescent bulbs contain small amounts of mercury. Dispose of used bulbs according to local environmental regulations. Do not discard with regular household waste.
- Operating Temperature: Do not use in enclosed fixtures unless specifically rated for such use, as excessive heat can reduce bulb life.
- Dimming: This bulb is not designed for use with dimmers unless the fixture and bulb are specifically rated as dimmable.
3. Setup and Installation
Follow these steps for proper installation:
- Verify Compatibility: Confirm that your lighting fixture is designed for a 2-pin (G23) compact fluorescent bulb of 9 watts.
- Power Off: Turn off the power to the light fixture at the main circuit breaker or fuse box.
- Remove Old Bulb (if applicable): If replacing an existing bulb, allow it to cool completely. Grasp the base of the old bulb and gently pull it straight out from the socket. Do not twist.
- Unpack New Bulb: Carefully remove the new Philips PL-S 9W/841/2P ALTO bulb from its packaging. Avoid touching the glass tubes directly.
- Insert New Bulb: Align the two pins on the bulb's base with the corresponding slots in the fixture's socket. Gently push the bulb straight into the socket until it is firmly seated. Do not force the bulb.
- Restore Power: Once the bulb is securely installed, restore power to the fixture at the circuit breaker.
- Test: Turn on the light switch to confirm proper operation.

4. Operating Instructions
Once installed, the Philips PL-S 9W/841/2P ALTO bulb operates like any standard light source connected to a switch.
- Turning On/Off: Use the wall switch or fixture switch to turn the light on or off.
- Warm-up Time: Fluorescent bulbs may require a brief warm-up period to reach full brightness, especially in colder environments.
- Frequent Switching: Frequent switching (turning on and off rapidly) can reduce the lifespan of fluorescent bulbs. It is recommended to leave the light on for a reasonable duration once activated.
5. Maintenance
Minimal maintenance is required for this compact fluorescent bulb.
- Cleaning: Ensure the power is off and the bulb is cool before cleaning. Gently wipe the glass tubes with a soft, dry, lint-free cloth. Do not use liquid cleaners or abrasive materials.
- Replacement: Replace the bulb when it reaches the end of its operational life (indicated by flickering, dimming, or failure to light). Follow the installation steps in Section 3 for replacement.
6. Troubleshooting
If the bulb does not operate correctly, consider the following:
- Bulb Not Lighting:
- Check if the power switch is on.
- Ensure the bulb is fully and correctly seated in the socket.
- Verify that the circuit breaker for the fixture has not tripped.
- Test the fixture with a known working bulb to rule out a fixture issue.
- The bulb may have reached the end of its lifespan and requires replacement.
- Flickering:
- Flickering can occur during the initial warm-up period.
- Ensure the bulb is securely seated.
- Flickering can also indicate the bulb is nearing the end of its life.
- Verify the fixture is not connected to an incompatible dimmer switch.
- Dim Light Output:
- Ensure the bulb has had sufficient warm-up time.
- The bulb may be old and losing brightness, indicating it needs replacement.
