As someone who’s been in the lighting industry, specifically with James Lighting, the nuances and intricacies of such components have always fascinated me.

Why is it called G9?

The naming conventions in lighting often have logic behind them.

The “G” in G9 stands for “glass”, referencing the primary material used in traditional bulbs for this holder. The “9” denotes the 9mm distance between the two pins of the bulb. It’s this uniformity in naming and design that helps industry professionals like us at James Lighting ensure the right product reaches the right customer.
