Bi-pin bulbs are tiny light bulbs with two prongs and specific pin spacing. They are identified by the space between the pins, the wattage and a voltage of between six and 120 volts. Halogen bi-pin bulbs are also known as JCD or JC lamps and are often used in display lighting or task lighting. The 12 volt LED and halogen bi-pin bulbs provide high illumination in a small space.
