Description

The Energizer G9 LED is a 4.2W capsule bulb producing 470 lumens of warm white 2700K light, designed to replace traditional 40W halogen G9 bulbs. The compact capsule shape fits directly into G9 bi-pin sockets commonly found in wall lights, pendant fittings, under-cabinet lighting and decorative chandeliers. This twin pack provides two bulbs rated for a 15-year lifespan based on 3 hours daily use.

Suited to kitchens, bathrooms, living rooms and commercial hospitality settings where warm accent or task lighting is needed, the G9 capsule fits into compact fittings where larger bulb shapes cannot. The 470-lumen output provides sufficient brightness for reading lights, vanity mirrors, decorative wall sconces and under-cabinet kitchen lighting without the heat output of a halogen equivalent. The bulb is non-dimmable and operates on standard 230V mains.

The warm white 2700K colour temperature produces a soft, welcoming light comparable to traditional incandescent and halogen sources, making it appropriate for residential interiors where cooler LED tones would feel clinical. The capsule measures approximately 15mm diameter and 50mm length, matching the form factor of the halogen G9 bulbs it replaces. Each bulb carries an E energy rating under current EU lighting efficiency classifications.

Frequently Asked

Can this bulb be used with a dimmer switch?

No. This G9 LED is non-dimmable and should only be used with standard on/off switching. Installing it in a dimmer-controlled circuit may cause flickering, reduced lifespan or failure.

What's the equivalent halogen wattage?

This 4.2W LED produces 470 lumens, equivalent to a 40W halogen G9 capsule bulb. The energy saving is approximately 90% compared to the halogen it replaces.

How long does the bulb last?

Energizer rates this LED for a 15-year lifespan based on 3 hours daily use. In practice this means approximately 16,000-20,000 hours of operation before noticeable lumen degradation.

Will it fit my existing G9 fitting?

The capsule dimensions match standard halogen G9 bulbs at approximately 15mm diameter and 50mm length. It fits any G9 bi-pin socket, but check your fitting allows adequate ventilation — enclosed or tightly sealed fittings may reduce LED lifespan.
