G9 LED lamps are smaller than their LED counterparts and use two small pins for connecting to the circuit. Other than for decorative use, you rarely will find G9 LED lamps sold individually. Instead, they get mounted together on one base which will have about 10 G9 LEDs. You may wonder why you’d want to bother with 10 small LEDs instead of just 1 larger LED. However, even with a set of G9 LED lamps which use the same wattage as a single, say E27 LED, you get some differences. LED lamps don’t emit light in the same way as incandescent bulbs: the LEDs tend to be directional so won’t have as large as a beam angle. By combining numerous G9 LED lamps on one base, you can expand the directionality of the LEDs greatly. It is very common to find G9 LED lamps which have 360 degree beam angles, meaning that they will illuminate all around. These types of G9 LED lamps are best for household lamps. Some G9 LED lamps are flat mounted though which gives them an omnidirectional beam angle. Then, you can expect a beam angle of about 120 degrees, which makes them ideal for spotlights.
