Description

The Energizer G9 LED capsule is a 4.9W dimmable bulb delivering 470 lumens of 2700K warm white light through a compact G9 bi-pin base. The bulb replaces traditional 40W halogen G9 capsules found in chandeliers, wall lights, desk lamps and enclosed fittings, cutting energy consumption by approximately 88% while maintaining comparable light output.

The G9 bi-pin base fits directly into G9 lampholders without adapters or modification, making retrofitting existing halogen fittings straightforward. The dimmable LED works with most household trailing-edge and some leading-edge dimmers, allowing brightness adjustment from full 470lm output down to a low ambient glow. This suits dining rooms, living rooms, bedrooms and hallways where variable light levels are needed throughout the day.

The 2700K colour temperature produces a warm white tone comparable to traditional incandescent and halogen bulbs, avoiding the cooler blue-white cast of higher Kelvin LEDs. The capsule body measures approximately 50mm in length and 16mm in diameter, fitting most decorative fittings designed for halogen G9 bulbs. Energizer rates the bulb at 15,000 hours average lifespan under typical domestic use, equivalent to roughly 15 years at 3 hours per day.

Frequently Asked

Is this compatible with dimmer switches?

Yes. The bulb is dimmable and works with most trailing-edge dimmers and some leading-edge models. Performance depends on the specific dimmer — if the bulb flickers or fails to dim smoothly, the dimmer may need upgrading to an LED-compatible model. Test with your existing dimmer before purchasing multiple bulbs.

What halogen wattage does this replace?

The 4.9W LED replaces a 40W halogen G9 capsule. Both deliver approximately 470 lumens, so light output remains comparable while energy consumption drops by around 88%.

Will it fit my existing G9 chandelier or wall light?

The bulb uses a standard G9 bi-pin base and fits any fitting designed for G9 halogen capsules. The LED body is approximately 50mm long and 16mm in diameter, similar in size to most halogen G9 bulbs, so it should fit decorative shades and enclosed fittings without clearance issues.

How long does it last compared to halogen?

Energizer rates this LED at 15,000 hours average lifespan. A typical halogen G9 lasts 2,000 hours. At 3 hours per day the LED should last approximately 15 years versus 2 years for halogen, reducing replacement frequency and overall running costs.
