Introduction
This manual provides essential information for the safe and effective use of your Satco S8302 2700K 7-Watt G23 Base T4 Twin 2-Pin Fluorescent Lamp. Fluorescent lamps are phosphorous-coated tubes filled with a low-pressure mercury vapor. Light is produced by passing an electric arc between tungsten cathodes at opposite ends of the tube. This process causes the mercury vapor to generate radiant energy, resulting in illumination. Please read this manual thoroughly before installation and operation.
Safety Information
Always adhere to the following safety precautions to prevent injury or damage:
- Power Disconnection: Always disconnect power to the fixture before installing, removing, or servicing the lamp. Failure to do so may result in electric shock.
- Proper Ballast: This lamp is designed for use with magnetic ballasts. Ensure your fixture has the correct ballast type. Using an incompatible ballast may damage the lamp or fixture.
- Handle with Care: Fluorescent lamps contain a small amount of mercury. Handle with care to avoid breakage. In case of breakage, follow local guidelines for cleanup and disposal.
- Do Not Dim: This lamp is not designed for use with dimmers unless explicitly stated on the product packaging or the lamp itself.
- Indoor Use: This product is intended for indoor use in dry locations unless otherwise specified.
- Correct Base: Ensure the lamp base (G23) matches the fixture socket. Do not force the lamp into an incompatible socket.
- Disposal: Dispose of used lamps according to local environmental regulations, as they contain mercury.

Setup and Installation
- Turn Off Power: Before beginning installation, ensure the power supply to the fixture is completely turned off at the circuit breaker or fuse box. This is a critical safety step.
- Remove Old Lamp (if applicable): If replacing an existing lamp, carefully remove it from the fixture. Allow it to cool if it has been recently in use.
- Inspect Fixture: Check the fixture's socket for any damage or debris. Ensure it is clean and dry. Verify that the fixture uses a G23 2-pin base and a magnetic ballast.
- Insert New Lamp: Align the two pins of the Satco S8302 lamp with the corresponding slots in the fixture's G23 socket. Gently push the lamp straight into the socket until it is firmly seated. Do not twist or force the lamp, as this may damage the pins or the socket.
- Secure Lamp: Ensure the lamp is fully inserted and stable in the socket.
- Restore Power: Once the lamp is securely installed, restore power to the fixture at the circuit breaker or fuse box.
- Test Operation: Turn on the light switch to confirm the lamp is functioning correctly.
If the lamp does not light up, ensure it is fully seated and that power is restored to the fixture. If issues persist, refer to the Troubleshooting section.
Operating Instructions
The Satco S8302 fluorescent lamp operates like any standard light bulb once installed in a compatible fixture. Simply use the wall switch or fixture control to turn the light on and off.
- Initial Start-up: Fluorescent lamps may take a moment to reach full brightness upon initial activation, especially in colder environments.
- Frequent Switching: While durable, frequent on/off cycling can reduce the lifespan of fluorescent lamps. For areas where lights are turned on and off many times a day, consider alternative lighting solutions if lamp longevity is a primary concern.
- Color Temperature: The 2700K color temperature provides a warm, soft white light, ideal for creating a comfortable and inviting atmosphere.
Maintenance
Minimal maintenance is required for the Satco S8302 lamp. Follow these guidelines to ensure optimal performance and longevity:
- Cleaning: Ensure the lamp is cool and the power is off before cleaning. Gently wipe the lamp with a soft, dry, lint-free cloth. Do not use liquid cleaners or abrasive materials, as they may damage the lamp's surface or internal components.
- Regular Inspection: Periodically check the lamp and fixture for any signs of damage, loose connections, or unusual operation.
- Replacement: Replace the lamp when it reaches the end of its useful life (indicated by flickering, dimming, or failure to light). Refer to the Setup and Installation section for replacement procedures.
