G4 LED Bulbs: 12V Bi-Pin for Accent & Landscape

The G4 bulb is one of the smallest and most specialized lamps in the lighting world. These tiny light bulbs are defined by their compact size and two small, straight pins spaced 4 millimeters apart. Our G4 LED bulbs operate exclusively on 12V (low-voltage) power, making them the standard landscape bulb and the ideal replacement for high-heat halogen lamps in sensitive fixtures.

Key Advantages of the G4 Low-Voltage System

The G4's miniature size and low voltage operation provide maximum flexibility for specialty lighting.

  • Ultimate Miniaturization: The G4 bulb design is perfect for incredibly small and restrictive fixtures like desk lamps, puck lights, and low-profile landscape fixtures.
  • Low-Voltage Safety: Operating at 12V, the bi pin G4 base is inherently safer for outdoor wiring and specialty applications, eliminating the shock risk associated with standard line voltage.
  • Energy Efficiency: As G4 LED bulbs, they replace 20W or 35W halogen versions, providing significant energy savings without requiring a new fixture.
  • Ideal for DC Power: These 12V G4 bulbs are essential for battery-powered systems in RVs, boats, and off-grid setups.

Where to Install Your G4 LED Light Bulbs

The G4 is essential for focused, low-voltage task and accent lighting.

  • Landscape & Pathway Lighting: The primary application for 12V LED bulbs, where G4s illuminate walkways, decks, and garden accents.
  • Desk & Reading Lamps: Used in modern, compact desk lamps that are designed with minimal space for the light source.
  • RV & Marine Lighting: The G4's 12V operation makes it a standard choice for cabin lighting in boats, RVs, and campers.
  • Display & Accent Lighting: Ideal for small jewelry cases, shelf lighting, and puck lights.

Frequently Asked Questions

What does the "4" in G4 signify?

The number "4" signifies that the distance between the center of the two small pins is 4 millimeters. This measurement is crucial for ensuring the bulb fits properly into the socket.

Do G4 bulbs require a transformer?

Yes. Since the G4 bulb operates on 12V (low voltage), it must be used with a transformer to step down the standard 120V household current. You cannot plug a G4 directly into a standard wall socket.

Can I use a G4 bulb in a G9 socket?

No. The G4 has a 4mm pin spacing, and the G9 has a 9mm loop-pin base. They are completely incompatible due to the difference in pin size, spacing, and often, voltage.

What is the typical light output range for a G4 LED bulb?

G4 LED bulbs typically replace 20W or 35W halogen bulbs and produce between 200 and 400 lumens. This focused light output is ideal for accent and task areas, not for general room illumination.

Why are these the standard for landscape lighting?

The 12V G4 system is preferred for landscape lighting because low-voltage wiring is much safer, easier to install without conduit, and meets most electrical codes for buried outdoor lines.
