A 2-pin fluorescent bulb is a type of compact fluorescent lamp (CFL) that uses two pins at one end of the bulb to connect to the fixture. These bulbs are typically energy-efficient and provide bright, diffused light. The two pins serve as the electrical contacts that connect the bulb to the socket, and they come in a variety of base types, such as G23, G24, and others, depending on the specific model and wattage.

These fluorescent bulbs typically emit cool, warm, or neutral white light and are commonly used for general lighting in offices, kitchens, and other commercial or residential settings. They tend to last longer than incandescent bulbs and consume less electricity, making them an eco-friendly option. The 2-pin design makes them distinct from the 4-pin or single-pin fluorescent bulbs.

They are often installed in fixtures with matching sockets, and it's important to match the bulb's wattage and voltage with the fixture for proper operation.
