Safety Information
Always follow basic safety precautions when using electrical products to reduce the risk of fire, electric shock, and personal injury.
- Ensure power is turned off at the circuit breaker before installation, removal, or inspection.
- Do not use in fully enclosed fixtures unless specified for CFL use, as this can shorten bulb life.
- Avoid touching the bulb with bare hands during operation or immediately after turning off, as it may be hot.
- Do not use with standard dimmer switches unless the bulb and fixture are specifically rated for dimmable CFLs. This bulb is dimmable.
- Dispose of broken bulbs according to local regulations, as they contain small amounts of mercury.
Setup and Installation
- Verify Compatibility: Ensure your fixture is designed for a G24q-2 base and 18-watt CFL bulbs.
- Power Off: Before installation, turn off the power to the fixture at the main circuit breaker or fuse box.
- Remove Old Bulb (if applicable): If replacing an existing bulb, allow it to cool completely. Gently twist and pull the old bulb straight out from the socket.
- Install New Bulb: Align the 4 pins of the Ushio BC8852 bulb with the slots in the G24q-2 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.
