WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov.
Always observe the following safety precautions:
- Disconnect Power: Always turn off power to the fixture at the circuit breaker before installing, removing, or servicing the bulb.
- Handle with Care: Fluorescent tubes contain a small amount of mercury. Handle with care to avoid breakage. If a bulb breaks, follow local guidelines for cleanup and disposal.
- Correct Base Type: Ensure the bulb's base (2GX7, 4-Pin) matches your fixture's socket type. Incorrect base types can cause damage or electrical hazards.
- Compatible Ballast: This bulb requires an electronic or dimming ballast. Using it with an incompatible ballast (e.g., magnetic ballast) may cause flickering, reduced lifespan, or failure.
- Do Not Overwatt: Do not exceed the maximum wattage rating of your light fixture.
- Indoor Use: This bulb is generally intended for indoor, dry location use unless otherwise specified by the fixture.
3. Installation
Follow these steps to properly install your Satco S8369 Compact Fluorescent Tube:
- Turn Off Power: Before beginning, ensure the power supply to the light fixture is completely turned off at the circuit breaker or fuse box.
- Allow Cooling: If replacing an existing bulb, allow the old bulb to cool down completely before handling.
- Remove Old Bulb (if applicable): Gently twist or pull the old bulb straight out from the socket, depending on the fixture type. Avoid forcing it.
- Inspect Fixture: Check the fixture's socket for any damage or debris. Ensure it is clean and dry.
- Insert New Bulb: Align the four pins of the Satco S8369 bulb with the corresponding slots in the 2GX7 socket. Gently push the bulb straight into the socket until it is firmly seated. Do not twist or force the bulb, as this can bend the pins or damage the socket.
- 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 the bulb is working correctly.


4. Operation
The Satco S8369 fluorescent tube is designed for straightforward operation once installed in a compatible fixture with an electronic or dimming ballast.
- Power On/Off: Use the standard wall switch or fixture control to turn the light on and off.
- Dimming Functionality: If your fixture is equipped with a compatible dimming ballast and dimmer switch, this bulb can be dimmed. Follow the instructions for your specific dimmer switch for proper operation.
- Color Temperature: The 4100K color temperature provides a bright white light, often described as cool white, suitable for task lighting, offices, and general illumination where a crisp, clear light is desired.

5. Maintenance
The Satco S8369 Compact Fluorescent Tube requires minimal maintenance. Regular cleaning can help maintain optimal light output.
- Cleaning: Ensure the power is off and the bulb is cool before cleaning. Gently wipe the glass tube with a soft, dry, lint-free cloth. Do not use liquid cleaners or abrasive materials, as these can damage the bulb or leave residues.
- Replacement: Replace the bulb when it reaches the end of its rated lifespan (approximately 15,000 hours) or if it begins to flicker excessively or fails to illuminate.
- Disposal: Due to the small amount of mercury contained in CFLs, proper disposal is important. Do not dispose of in regular household trash. Check with your local waste management authority for recycling or hazardous waste disposal options in your area. Many retailers also offer recycling programs for fluorescent bulbs.
