2. Safety Information
- WARNING: Risk of Electric Shock. Always turn off power to the fixture at the circuit breaker or fuse box before installing or removing the bulb.
- Do not use with dimmers unless the bulb is specifically rated for dimmer use.
- Do not use in enclosed fixtures unless the bulb is specifically rated for enclosed fixture use, as this can shorten bulb life.
- Avoid touching the bulb with bare hands during operation or immediately after turning off, as it can become very hot and cause burns.
- Ensure the bulb is securely screwed into the socket to prevent accidental dislodging.
- Dispose of broken bulbs safely according to local regulations.
3. Setup and Installation
- Turn off power: Locate the light fixture's power switch and turn it to the OFF position. For added safety, turn off power at the main circuit breaker or fuse box.
- Allow cooling: If replacing an old bulb, allow it to cool completely before handling.
- Unpack the new bulb: Carefully remove the Satco S3628 bulb from its packaging. Avoid touching the glass with excessive force.
- Screw in the bulb: Gently screw the bulb clockwise into the compatible intermediate (E17) base socket until it is snug. Do not overtighten.
- Restore power: Turn the power back on at the circuit breaker or fuse box, then use the light fixture's switch to test the bulb.

Bulb Does Not Light Up:

- Check Connection: Turn off power, then carefully re-tighten the bulb in the socket to ensure a proper electrical connection.
- Inspect Bulb: Turn off power and remove the bulb. Check the filament for breakage. If the filament is broken, the bulb needs to be replaced.
