Selecting The Best Replacement Bi-Pin Socket

One of the most challenging issues in repairing a light halogen or a fluorescent type of light fixture is in selecting the right type of bi-pin socket. This is a specially designed socket that differs based on the specifics of the bulbs they are designed to hold.

Safety Considerations

Through the use of the correct bi-pin socket, the manufacturer of the fixture can safeguard the system by eliminating the option for the end-user to upgrade to a higher power bulb. The different configurations of the pins on the light bulb and the pinholes in the socket make it impossible to insert the pins of a higher-powered bulb into the socket designed for a lower powered bulb. To ensure the entire fixture is safe and does not overheat during use, it is essential to choose the same type of replacement socket.

Type of Pins

If the information about the current bi-pin socket in the fixture is not available, it is possible to know the type of socket required by a closer look at the bulb. In most cases, the bulb will be designated as a G or a GU, but there are several other specialized designations for particular light usage. The U designates the base of the pin has an expanded area. These are sometimes called a peg.

The number after the letter designation stipulates the spread or the distance between the pins in millimeters. For example, a G8 indicates a standard pin with 8mm from pin center to pin center. The GU10 has the peg rather than the pin design, and the distance from center to center of the pins is 10mm.

Mount Options

The mounting options for these sockets include the flush-mount, low profile straight insertion, and a slide on option. There are also tall mount and low profile styles, all designed to fit with different fixtures to secure the bulb in place.
