G4 Globes, Low-Voltage LED for Wet Areas, Caravans, and Under-Cabinet Lighting

The G4 bi-pin globe is the foundation of low-voltage LED lighting in Australian homes, caravans, and commercial spaces. Dulora's G4 globe range is available in 12V and 24V AC/DC configurations, covering under-cabinet kitchen lighting, bathroom wet area zones compliant with AS/NZS 3000, caravan and marine interior lighting, and architectural low-voltage installations. Each G4 globe is engineered to CRI 90+, rendering colour accurately in low-voltage compact applications with dimmable performance across the full low-voltage range. For compliant wet area bathroom installations, the 12V G4 globe in an IP-rated fitting is the correct product choice under Australian wiring standards.

G4 Globes: The Low-Voltage LED Specialist for Wet Areas, Caravans, and Under-Cabinet Lighting

The G4 globe is a specialist product for a specialist application. Unlike standard 240V globes that fit the general-purpose fittings most Australian homes use, the G4 bi-pin is designed for low-voltage systems where 240V is either not appropriate, not compliant, or not practical. Understanding where the G4 belongs and how to use it correctly is the key to getting compliant, long-lasting results in these applications.

What is a G4 base?

The G4 is a bi-pin base with two parallel pins spaced 4mm apart, designed for low-voltage capsule fittings. G4 globes operate at 12V or 24V rather than the standard 240V mains voltage used by most residential fittings. They require a compatible driver or transformer to step down the mains voltage to the correct operating voltage for the globe.

Where is G4 used in Australian homes?

Under-cabinet kitchen lighting is the most common residential G4 application, where compact 12V fittings mounted beneath overhead cabinets provide directed task lighting on benchtops without requiring mains voltage wiring in the cabinet structure. Bathroom wet area zones are one of the most important G4 applications from a compliance perspective. Under AS/NZS 3000, certain bathroom zones require low-voltage lighting in IP-rated fittings, and a 12V G4 globe in a compliant IP-rated fitting is the correct product for these zones.

Caravan and marine interior lighting relies heavily on G4 globes because these environments typically run 12V DC systems. Dulora G4 globes are available in 12V and 24V AC/DC universal configurations, making them compatible with both AC transformer-based installations and DC battery or solar systems.

What driver do I need for G4 LED globes?

G4 LED globes require a constant-voltage LED driver matched to the operating voltage of the globes in the circuit. The driver must be rated for the combined wattage of all G4 globes it powers, with a safety margin of at least 20 per cent above the total load. For dimmable G4 installations, the driver must also be a dimmable LED driver compatible with the dimmer switch being used.

Frequently Asked Questions: G4 Globes

• What voltage do G4 LED globes operate at?
• Dulora G4 LED globes are available in 12V and 24V AC/DC universal configurations. They require a compatible constant-voltage LED driver to step down from standard 240V mains voltage. They cannot be connected directly to a 240V mains circuit without a driver.
• Are G4 globes suitable for bathroom wet area installations?
• Yes, when used correctly. Under AS/NZS 3000, certain bathroom zones require low-voltage lighting in IP-rated fittings. A 12V G4 globe in a compliant IP-rated fitting is the correct product for these zones. The globe itself does not need an IP rating; the fitting must carry the appropriate IP rating for the zone it is installed in.
• What is the difference between G4 and G9 globes?
• G4 and G9 are both bi-pin capsule bases, but G4 operates at low voltage (12V or 24V) while G9 operates at mains voltage (240V). They are not interchangeable and serve different applications. G4 is used in low-voltage systems including wet areas, caravans, and under-cabinet lighting. G9 is used in mains-voltage pendant lights, wall sconces, and vanity fittings.
• What CRI rating do Dulora g4 globes have?
• Dulora g4 globes are built to CRI 90+ across the range. This means warm tones, textiles, and colour appear natural and accurate rather than flat or washed out, which is a visible difference compared to standard CRI 80 globes.
• Why is flicker-free technology important for your home?
• Invisible flicker from low-quality LED drivers causes eye strain, headaches, and fatigue even when you cannot consciously detect it, because the human nervous system responds to rapid light fluctuations below the threshold of conscious perception. Dulora G4 LED globes use premium constant-current drivers that eliminate flicker entirely, meeting IEC flicker guidance standards with Pst LM below 1 and SVM below 0.4, at every dimming level from 1 to 100 per cent. Flicker-free performance matters throughout the home, but it is most noticeable in fittings used at low dimming levels for extended periods.
• Are Dulora G4 globes SAA certified?
• Yes. All Dulora G4 globes are SAA certified and backed by a three-year warranty. They are designed for compliant low-voltage installations in Australian homes, caravans, and commercial spaces.
