G9 LED Plug-in lights are capsule-shaped lights with a 9 mm distance between the pins. These lamps can be connected to 230V, so no transformer is required. These capsule lamps can therefore replace your G9 halogen lamp 1:1. G9 lamps are often used in small fixtures or places with limited space. The LED version of these G9 lights lasts up to 10 times longer than halogen lights and is also more resistant to shocks. When replacing your current lighting, pay attention to the format, this can vary per lamp. The height of the G9 LED lamp in particular can deviate from the halogen version.
