Energizer 4.2W Dimmable LED Candle Bulb E27 2700K Warm White

The Energizer 4.2W LED candle bulb is a dimmable E27 replacement for traditional 40W incandescent candle bulbs, delivering 470 lumens at 2700K warm white. The frosted candle-shaped envelope diffuses light evenly, making it suitable for chandeliers, wall sconces, table lamps and decorative fittings where the bulb shape is partially or fully visible.

Built for residential use in living rooms, dining rooms and bedrooms, the bulb supports dimmer switches, allowing brightness adjustment from full output down to a low glow. The 2700K colour temperature produces a soft amber-toned white that mimics traditional tungsten filament lamps, avoiding the cooler blue-white cast of higher-temperature LEDs. The bulb fits any standard E27 (Edison screw) socket and operates on 230V mains.

Energizer rates this LED at a 15-year average lifespan based on 3 hours daily use, equating to approximately 16,425 hours before failure. The 4.2W power draw reduces energy consumption by around 89% compared to the 40W incandescent it replaces, while the 470 lumens maintain similar perceived brightness. The bulb carries an energy rating of E under the updated UK energy label scale.

The frosted finish on the glass envelope softens the LED chip inside, preventing visible point-source glare when the bulb is used in open or semi-open fittings. The candle profile measures approximately 37mm diameter by 98mm height, making it compact enough for tight lamp shades and narrow sconce arms where a standard GLS bulb would protrude.

Is this bulb compatible with all dimmer switches?

The bulb is rated dimmable, but compatibility depends on the specific dimmer model. Leading-edge (resistive) dimmers generally work better with LED bulbs than trailing-edge types. If the bulb flickers or fails to dim smoothly, the dimmer may need replacing with an LED-compatible model.

What does the 15-year lifespan mean in practice?

Energizer bases the 15-year claim on 3 hours of use per day, which totals approximately 16,425 hours. Heavier use shortens the calendar lifespan but the bulb still delivers the same total hours. Light use extends the calendar lifespan beyond 15 years.

Can this replace a 40W incandescent in a chandelier?

Yes. The 470 lumens output matches the brightness of a typical 40W incandescent candle bulb. The frosted finish and candle shape suit decorative fittings where the bulb is visible, and the 2700K warm white mimics the colour of traditional tungsten lamps.

What does the E energy rating mean?

The E rating sits in the mid-lower range of the updated UK energy label scale, which runs from A (most efficient) to G (least efficient). Most LED bulbs now fall into the C-E range following the recalibration of the scale in 2021.
