Energizer 5W Dimmable LED Candle Filament Bulb E14 - Cool White 4000K

The Energizer 5W LED candle bulb combines filament-style aesthetics with modern LED efficiency in a compact E14 fitting. The bulb delivers 550 lumens at 4000K cool white, producing a crisp, neutral light that works in task-focused rooms like kitchens, home offices and utility spaces. The visible filament strips inside the clear candle-shaped glass give a decorative appearance when installed in open-bulb chandeliers, wall sconces and table lamps.

Designed as a direct replacement for 40W halogen candle bulbs, the Energizer runs at 5W while maintaining comparable brightness. The dimmable capability allows the light level to be adjusted from full brightness down to around 10% depending on the dimmer switch used, giving control over task lighting intensity or creating softer accent light in the evening. The E14 small Edison screw base fits standard UK candle-bulb fixtures.

The cool white 4000K colour temperature sits between warm white (2700-3000K) and daylight white (5000-6500K), providing a clean, neutral tone that reduces the yellow cast of warm bulbs without the clinical harshness of daylight LEDs. This colour temperature suits kitchens, bathrooms and workspaces where colour accuracy matters. The bulb carries an E energy rating under current UK energy labelling regulations, with a rated lifespan of 15,000 hours based on typical domestic use patterns.

Is this bulb compatible with all dimmer switches?

The Energizer 5W candle is dimmable, but performance depends on the specific dimmer model. LED-compatible trailing-edge dimmers give the smoothest dimming range. Older leading-edge dimmers designed for halogen bulbs may cause flicker or limit the dimming range. Test with your existing dimmer or confirm compatibility before purchasing multiple bulbs.

What does 4000K cool white look like compared to warm white?

4000K produces a neutral, clean white light without the yellow warmth of 2700-3000K bulbs or the blue-tinted harshness of 5000K+ daylight bulbs. It provides better colour accuracy for tasks like food preparation, reading fine print or applying makeup, while still feeling natural rather than clinical.

How long does the bulb last?

Energizer rates this bulb at 15,000 hours typical lifespan. At 3 hours per day usage, that equates to around 13-14 years before noticeable light degradation. Actual lifespan varies depending on usage patterns, operating temperature and the number of on-off cycles.

Can this replace a 40W halogen candle bulb directly?

Yes. The 550 lumens output is comparable to a standard 40W halogen candle bulb, while consuming only 5W. The E14 base fits the same socket, making it a direct swap in most fixtures. Check that the bulb's physical dimensions fit within any lampshade or enclosed fitting.
