Energizer 4.2W G9 LED Capsule Bulb 470lm 2700K Warm White - Non-Dimmable

The Energizer G9 LED capsule bulb delivers 470 lumens of 2700K warm white light from a 4.2W LED chip, replacing a 40W halogen capsule with approximately 90% lower energy consumption. The G9 bi-pin base fits standard 9mm push-fit lamp holders common in wall lights, ceiling spotlights, under-cabinet lighting and decorative chandeliers.

Designed for fixed-output applications where dimming is not required, the bulb provides consistent warm white light suited to living rooms, bedrooms, hallways and hospitality settings. The 300-degree beam angle spreads light broadly from the compact 16mm x 51mm capsule body, filling shades and diffusers without creating harsh shadows. The bulb operates on 220-240V mains supply and starts at full brightness immediately without warm-up delay.

Energizer rates the bulb at 15,000 hours or approximately 15 years based on 3 hours daily use. The capsule construction uses a clear polycarbonate body over the LED array, giving visibility of the light source when used in open fixtures. The warm 2700K colour temperature produces a yellowish-white tone similar to traditional incandescent and halogen bulbs, making it compatible with interiors where cooler LED temperatures would appear too clinical.

The non-dimmable design means the bulb should not be installed on circuits controlled by dimmer switches, as this can cause flickering, buzzing or premature failure. For rooms requiring adjustable light levels, select a dimmable G9 LED from the bulbs category instead.

Can this bulb be used with a dimmer switch?

No. This is a non-dimmable LED bulb and should not be installed on circuits controlled by dimmer switches. Using it with a dimmer can cause flickering, audible buzzing and may shorten the bulb's lifespan. If dimming is needed, select a dimmable G9 LED instead.

What does 2700K warm white look like?

2700K produces a yellowish-white light similar to traditional incandescent and halogen bulbs. It is warmer and more amber-toned than daylight or cool white LEDs, making it well-suited to living rooms, bedrooms and areas where a relaxed atmosphere is preferred over clinical brightness.

How does 470 lumens compare to a halogen?

470 lumens is approximately equivalent to a 40W halogen capsule bulb. This makes the Energizer 4.2W LED a direct replacement for standard G9 halogens in wall lights, ceiling spots and decorative fittings, with the same light output but much lower heat and energy use.

How long will the bulb last?

Energizer rates this bulb at 15,000 hours, which translates to approximately 15 years when used for 3 hours per day. Actual lifespan depends on usage patterns, operating temperature and mains voltage stability.
