G4 Bulbs: The Low-Voltage Bi-Pin for Wet Areas, Campervans, and Compact Installations
What is a G4 bulb and where is it used?
A G4 bulb is a compact LED with a bi-pin base where the two pins are spaced 4mm apart. It operates at low voltage rather than mains voltage, making it the standard choice for wet-area zones, under-cabinet kitchen lighting, campervan interiors, and architectural accent lighting.
The compact physical size fits into small recessed downlight housings and slim under-cabinet fittings that larger bulb forms can't serve.
Which G4 voltage do I need: 12V or 24V?
12V is the standard for most residential applications: wet-area fittings, under-cabinet kitchen lighting, and campervan systems running on 12V batteries. 24V is used in commercial low-voltage installations and larger systems where reduced cable current is preferred.
