Description

The Energizer 5W LED golf ball bulb uses visible filament LEDs inside a clear glass golf ball shell to deliver 550 lumens at 2700K warm white. The E27 screw base fits standard UK lamp holders and the bulb is fully dimmable when paired with compatible LED dimmer switches. At 5W it replaces a 40W incandescent while drawing one-eighth of the power.

Designed for decorative fittings where the bulb itself is visible, the golf ball shape and exposed filament strands give a vintage incandescent appearance while running on LED technology. The bulb suits table lamps, pendant lights with open shades, wall sconces and chandeliers where multiple bulbs are clustered. The 2700K colour temperature provides a warm glow closer to traditional tungsten than cooler daylight LEDs.

The clear glass housing measures approximately 45mm diameter, typical for a golf ball bulb, and sits comfortably in compact lampshades without protruding. The filament strands inside are visible when the bulb is off, adding decorative interest even when not lit. Energizer rates the bulb at 15,000 hours lifespan under typical use, equivalent to approximately 15 years at three hours per day.

The Energy Rating E reflects the efficiency standard for small decorative LED bulbs with filament styling. While not as efficient as non-filament LEDs in the same wattage category, the visible filament design prioritises aesthetic compatibility with period and traditional fittings where a modern LED bulb would look out of place.

Frequently Asked

Is this bulb dimmable with all dimmer switches?

The bulb is rated as dimmable but performance depends on the dimmer model. LED-compatible trailing-edge dimmers give the best results. Older leading-edge dimmers designed for incandescent bulbs may cause flickering or limited dimming range. Check your dimmer's compatibility with LED bulbs before pairing.

What does 'golf ball' mean?

Golf ball refers to the compact spherical shape, approximately 45mm in diameter. This bulb shape suits smaller lampshades, chandeliers with multiple bulb positions, and decorative fittings where a full-size GLS bulb would be too large.

How does the light colour compare to old incandescent bulbs?

At 2700K this bulb produces a warm white light very close to traditional tungsten incandescent bulbs, which typically operated at 2700-2800K. It avoids the cooler, bluer tone of daylight LEDs rated at 4000K or above.

What is the actual lifespan?

Energizer rates this bulb at 15,000 hours. At three hours per day that works out to approximately 15 years. Lifespan reduces with higher daily usage or frequent on-off cycling, which stresses LED drivers more than continuous operation.
