Energy-saving lamps come in two main types: self-ballasted fluorescent lamps (commonly known as electronic energy-saving lamps) and single-ended fluorescent lamps, also referred to as PL plug-in energy-saving tubes.
Self-ballasted fluorescent lamps are designed with a built-in ballast and starter circuit, making them fully integrated units. These lamps typically feature a screw or bayonet base, and the internal electronics are usually enclosed in a housing. The control circuit inside is primarily based on high-frequency electronic ballasts, which help improve efficiency and reduce flickering. This compact design allows these lamps to be directly installed into standard incandescent lamp sockets, making them an easy and convenient replacement for traditional bulbs.
On the other hand, single-ended fluorescent lamps are low-pressure mercury vapor discharge lamps that emit light through phosphor coatings activated by ultraviolet radiation. Unlike self-ballasted lamps, they are often used in specially designed luminaires and require external ballasts or drivers. These lamps can be removed from the fixture and are optimized for specific lighting needs. They typically have either a two-pin (2P) or four-pin (4P) base. The two-pin version includes a built-in starter (also called a glow starter) and an anti-interference capacitor, while the four-pin version does not contain any internal circuitry, relying instead on the luminaire’s control system.
Choosing between these two types depends on the application, installation requirements, and desired performance. Whether you're looking for a direct replacement for old incandescent bulbs or a more specialized lighting solution, energy-saving lamps offer a range of options to suit different needs.
