Description

The Energizer 1.2W G4 LED capsule bulb produces 90 lumens at 6500K daylight colour temperature through a compact capsule form factor with a bi-pin G4 base. The bulb draws 1.2W from 12V low-voltage supply, replacing a 9W halogen G4 bulb with equivalent light output while reducing heat generation and power consumption. The 300-degree beam angle provides wide light distribution suitable for task lighting rather than focused spotlighting.

Designed for 12V low-voltage fittings, the G4 base fits under-cabinet lights in kitchens, desk lamps, bedside reading lights, display case lighting in retail or home environments, and decorative accent lighting where halogen capsule bulbs were previously used. The 6500K daylight temperature suits workspaces and areas requiring high colour rendering and visibility — kitchens, workshops, garages and home offices — rather than ambient or mood lighting where warmer temperatures would be preferred.

The capsule measures approximately 35mm length including pins and 10mm diameter, fitting the same fixture footprint as a halogen G4. The LED chipset operates cooler than halogen equivalents, reducing the risk of heat damage to fabric or plastic shades in close-proximity applications. The bulb carries a 15-year rated lifespan based on average domestic use, significantly outlasting halogen capsules which typically fail within 2,000 hours. The bulb is non-dimmable and should not be paired with dimmer switches or variable transformers.

Frequently Asked

What voltage does this bulb require?

G4 bulbs operate on 12V low-voltage supply, typically provided by a transformer built into the fitting or installed separately in the ceiling void. The bulb will not work on 230V mains voltage without a transformer.

Can it be used with a dimmer?

No. The bulb is non-dimmable and should not be paired with dimmer switches or variable transformers, which may cause flickering, buzzing or premature failure.

What halogen bulb does it replace?

The 1.2W LED output matches a 9W halogen G4 capsule at approximately 90 lumens. If your existing halogen bulb is 10W or 20W, this LED will produce noticeably less light.

Is 6500K suitable for living rooms?

6500K is a cool daylight temperature that appears blue-white rather than warm yellow. It suits task lighting in workspaces, kitchens and garages but may feel harsh in living rooms or bedrooms where 2700K-3000K warm white is typically preferred.
