Energizer 4.2W Dimmable LED Golf Ball Bulb E27 2700K - Warm White

The Energizer LED Golf Ball is a 4.2W dimmable bulb with an E27 screw base, producing 470 lumens of warm white 2700K light. It replaces a traditional 40W incandescent golf ball bulb while using 89% less energy, and carries a rated lifespan of 15 years based on average domestic use of 2.7 hours per day.

Designed for table lamps, bedside lamps, wall lights and pendant fittings that take exposed or visible bulbs, the compact golf ball shape suits smaller lampshades and decorative fittings where a standard A60 bulb would be too large. The dimmable function works with most UK trailing-edge and leading-edge dimmers, allowing light levels to be adjusted from full 470 lumens down to a low glow for evening reading or background ambient light.

The 2700K colour temperature produces a warm incandescent-style tone that pairs well with warm-toned interiors, brass and wood finishes, and traditional or period decor. The bulb reaches full brightness instantly without warm-up delay, and the LED chipset provides flicker-free output that does not strobe under dimming. The frosted diffuser hides the internal LED array and gives a soft, even glow when viewed directly.

Energizer rates this bulb at 15,000 hours to failure, which translates to approximately 15 years when used 2.7 hours per day. The E27 base fits standard Edison screw sockets used throughout UK lighting fittings, and the bulb operates on 230V mains without requiring a transformer or external driver.

Is this bulb compatible with all dimmers?

The Energizer golf ball works with most trailing-edge and leading-edge dimmers designed for LED loads. Older dimmers designed only for incandescent bulbs may cause flickering or limited dimming range. If dimming performance is poor, upgrading to an LED-compatible dimmer module resolves the issue in most cases.

What does 40W replacement mean?

The 470 lumens output is approximately equivalent to the light produced by a traditional 40W incandescent golf ball bulb. The LED version achieves this brightness using only 4.2W, reducing energy consumption by around 89% compared to the incandescent it replaces.

Can it be used in enclosed fittings?

Yes. LED bulbs generate less heat than incandescent or halogen equivalents, so the Energizer golf ball is safe to use in fully enclosed pendant shades, wall lanterns and ceiling fittings where heat build-up would previously have shortened bulb life.

What is the colour temperature suitable for?

The 2700K warm white tone matches the colour of traditional incandescent bulbs, producing a soft, yellowish-white light. This suits living rooms, bedrooms, dining areas and any space where a cosy, relaxed atmosphere is preferred over the cooler, bluer tone of daylight LEDs.
