2. Safety Information
Please read and understand all safety instructions before installing or replacing the light bulb. Failure to follow these instructions may result in electric shock, fire, or personal injury.
- Power Disconnection: Always disconnect power to the fixture at the circuit breaker or fuse box before attempting installation, removal, or maintenance.
- Handle with Care: Fluorescent bulbs are made of glass and can break. Handle them carefully to avoid injury.
- Proper Disposal: Fluorescent bulbs contain small amounts of mercury. Dispose of them according to local regulations. Do not dispose of in regular household trash.
- Compatibility: Ensure the bulb's wattage, length, and base type (G5) match your fixture's requirements. Using an incompatible bulb can damage the fixture or cause a fire hazard.
- Indoor Use Only: This bulb is designed for indoor use in dry locations. Do not use in wet or damp environments unless the fixture is specifically rated for such conditions.
- Do Not Dim: This fluorescent bulb is not designed for use with dimmer switches unless explicitly stated on the fixture or ballast.
3. Setup and Installation
Follow these steps to safely install your new Westek fluorescent light bulb:
- Turn Off Power: Locate the circuit breaker or fuse that controls the power to the light fixture. Switch it to the "OFF" position. Verify that the power is off by attempting to turn on the light switch.
- Remove Old Bulb (if applicable): If replacing an old bulb, carefully grasp the old fluorescent tube near its ends and twist it approximately 90 degrees. Gently pull the bulb straight out of the sockets.
- Inspect Fixture: Check the fixture's sockets for any damage or corrosion. Ensure they are clean and free of debris.
- Insert New Bulb: Align the pins on both ends of the new Westek FA200WB bulb with the slots in the fixture's sockets. Gently push the bulb into the sockets until the pins are fully seated.
- Twist to Lock: Once the pins are seated, twist the bulb approximately 90 degrees until it locks securely into place. Do not force the bulb.
- Restore Power: Return to the circuit breaker or fuse box and switch the power back to the "ON" position.
- Test: Turn on the light switch to confirm the bulb is working correctly.
If the bulb does not light, refer to the Troubleshooting section.
4. Operation
The Westek FA200WB fluorescent light bulb operates immediately upon receiving power from a compatible fixture. Simply use the light switch connected to your fixture to turn the light on or off.
- Warm-up Time: Fluorescent bulbs may require a brief warm-up period (a few seconds) to reach full brightness, especially in colder environments.
- Frequent Switching: While designed for durability, excessively frequent switching (on/off cycles) can reduce the overall lifespan of fluorescent bulbs.
5. Maintenance
