Description
The Energizer G4 is a 1.2W LED capsule bulb with a bi-pin G4 base, delivering 90 lumens of warm white 2700K light. Designed as a direct replacement for 9W halogen G4 capsules, the bulb fits the same compact bi-pin socket and reduces energy consumption by approximately 85% while producing the same light output.
Used in decorative table lamps, under-cabinet lighting, reading lights, motorhome and caravan fixtures, and low-voltage display lighting, the G4 capsule fits any fitting that previously ran a halogen G4. The 300° beam angle provides omnidirectional light spread rather than a focused spot, making it suitable for general ambient and accent lighting rather than directional task light. The bulb operates on 12V DC or AC, making it compatible with both mains-voltage transformers and low-voltage LED drivers.
The capsule measures approximately 35mm in length and 10mm in diameter, matching the footprint of the halogen bulbs it replaces. The non-dimmable LED driver inside the bulb is rated for a 15-year lifespan under typical domestic use, significantly outlasting halogen capsules which typically last 2,000 hours. The warm white 2700K colour temperature matches incandescent and halogen tones, avoiding the cooler blue-white cast of higher Kelvin LEDs.

Frequently Asked
Is this bulb dimmable?
No. The Energizer G4 1.2W LED capsule is non-dimmable. Using it with a dimmer switch may cause flickering or damage to the bulb. If dimming is required, a separate dimmable G4 LED bulb is needed.
What voltage does it run on?
The G4 capsule operates on 12V AC or DC. It must be used with a 12V transformer or LED driver, not directly on 230V mains. Check your existing halogen transformer is rated for LED loads before switching.
Will it fit my existing G4 halogen fixture?
Yes. The G4 bi-pin base is a standard size matching halogen capsules. The bulb dimensions (approximately 35mm length, 10mm diameter) are the same as the halogen it replaces, so it fits any fixture that previously housed a G4 halogen bulb.
How long does it last?
Energizer rates this LED capsule for a 15-year lifespan under typical domestic use (approximately 3 hours per day). This significantly exceeds the 2,000-hour average lifespan of halogen G4 bulbs.
