No, this bulb requires a fixture with a 2G11 4-pin socket. Always check your fixture's compatibility before installation.

Yes, it is an energy-saving compact fluorescent lamp (CFL) that uses significantly less power than equivalent incandescent bulbs, leading to cost savings.

This 18W CFL bulb provides a light output equivalent to a 100W incandescent bulb.

Yes, for the dimming feature to work, you must use a dimmer switch that is specifically compatible with compact fluorescent (CFL) or LED dimmable bulbs. Not all dimmer switches are suitable.

CFL bulbs typically have a brief warm-up period of a minute or two to reach their full brightness. This is normal for the technology.

Ensure the power is on and the bulb is correctly seated in the 2G11 socket. Check if the fixture is compatible and the circuit breaker has not tripped. If dimmable, ensure it's not set to zero light output.

This could indicate a loose connection, an incompatible dimmer switch, or the end of the bulb's lifespan. Check the seating of the bulb and compatibility of the dimmer. If the issue persists, the bulb may need replacement.

Verify that the light fixture is connected to a compatible dimmer switch specifically designed for CFL bulbs. Ensure the dimmer is turned up sufficiently. Some older dimmer models may not be compatible.

This is normal for CFL technology, which requires a short warm-up period. If the delay is unusually long, check compatibility and ensure the bulb is not in an environment that is too cold, as this can affect performance.
