Energizer 4.2W Dimmable LED Golf Ball Bulb E14 4000K Cool White

The Energizer LED Golf is a 4.2W dimmable LED bulb with an E14 small Edison screw base, delivering 470 lumens of 4000K cool white light. The golf ball shape measures approximately 45mm diameter, making it suitable for compact fittings where a full-size GLS bulb would be too large — bedside lamps, vanity mirrors, wall sconces and multi-bulb chandeliers with narrow spacing between lamp holders.

Designed as a direct replacement for traditional 40W incandescent golf bulbs, the Energizer LED draws 4.2W to produce the same light output, cutting energy consumption by approximately 90%. The 4000K colour temperature sits between warm white and daylight, providing a neutral, crisp tone that works well in bathrooms, kitchens and task-focused areas where clarity is needed without the yellow cast of 2700K bulbs. The frosted glass envelope diffuses the LED chipset evenly, avoiding the harsh point-source glare of clear filament styles.

The bulb is fully dimmable when paired with compatible LED dimmer switches, allowing brightness to be adjusted from full 470 lumens down to low ambient levels. Dimmer compatibility depends on the specific dimmer model — older trailing-edge dimmers designed for incandescent loads may cause flicker or fail to dim smoothly, so pairing with a modern LED-compatible dimmer is recommended. The bulb carries an energy rating of E under the revised EU energy label scale and a stated lifespan of 15 years based on average domestic use of 3 hours per day.

Is this bulb dimmable with all dimmer switches?

The bulb is dimmable, but compatibility depends on the dimmer model. Modern LED-compatible dimmers (trailing-edge or universal types) will dim the bulb smoothly. Older dimmers designed only for incandescent loads may cause flicker, buzzing or limited dimming range. Check the dimmer manufacturer's LED compatibility list before pairing.

What fittings is the golf ball shape suitable for?

Golf ball bulbs suit compact fittings where space is limited — bedside lamps, vanity mirrors, wall sconces, pendant lights with narrow shades, and multi-bulb chandeliers or ceiling fittings where full-size GLS bulbs would be too large or cause bulbs to touch each other.

What's the difference between 4000K and 2700K bulbs?

4000K produces a neutral, cool white light with a slight blue tint, similar to overcast daylight. It provides clarity and contrast, making it useful in bathrooms, kitchens and task areas. 2700K produces a warm white light with a yellow tone, closer to traditional incandescent bulbs, and is typically chosen for living rooms and bedrooms where a warmer ambience is preferred.

How long does the bulb last?

Energizer states a 15-year lifespan based on average domestic use of 3 hours per day. Actual lifespan depends on usage patterns, ambient temperature and how often the bulb is switched on and off. Frequent switching and high ambient temperatures can reduce LED lifespan.
