What is Halogen G9 Bulb

The term "G9" refers to the type of base or socket used to connect the bulb to the fixture. G9 bulbs have a two-pin bi-pin base, which means they have two pins that protrude from the base and fit into a socket with corresponding holes.

The "G" in G9 stands for "glass," indicating that the base is made of glass. The number "9" refers to the distance between the two pins in millimeters. Therefore, a G9 bulb has two pins spaced 9mm apart.

Halogen G9 bulbs with different wattages (10W, 20W, 30W, 40W, 50W,60W,75W), and they all share a same size (Φ14*43mm).
