What is Self-Ballasted Lamp

A self-ballasted lamp, also known as an SB lamp, is designed with a built-in ballast, which eliminates the need for an external ballast. The ballast is responsible for regulating the electrical current flowing through the lamp, ensuring that it operates at the correct voltage and frequency.

One specific type of self-ballasted lamp is the self-ballasted compact fluorescent lamp (CFL). These lamps are equipped with a built-in electronic ballast that allows them to operate efficiently and produce high-quality light. They are known for their energy efficiency and long lifespan, making them a popular choice for both residential and commercial lighting applications.

The advantage of self-ballasted lamps is their convenience and versatility. They can be directly connected to the mains power supply, eliminating the need for additional wiring or equipment. This makes them suitable for a wide range of lighting fixtures and sockets.
