Description

The Energizer 5W LED golf ball bulb pairs a B15 small bayonet cap with visible filament LED strips behind a clear glass globe, producing 550 lumens of 2700K warm white light. The bulb draws 5W on 230V mains as a direct replacement for 40W incandescent golf balls, cutting energy consumption by 87% while maintaining equivalent light output.

Designed for smaller fittings where a standard GLS bulb would be too large, the compact golf ball profile suits chandeliers with multiple arms, bedside table lamps, wall sconces and decorative pendants with visible bulbs. The dimmable function works with most leading-edge and trailing-edge dimmer switches, allowing brightness to be adjusted from full 550-lumen output down to a low-level glow for evening ambience. The B15 cap is the smaller UK bayonet fitting, commonly found in older British light fittings and period-style reproductions.

The filament-style LED strips inside the bulb mimic the appearance of traditional carbon filament bulbs when lit, giving a warm glow through the clear glass without the fragility or short lifespan of genuine incandescent filaments. The 2700K colour temperature produces a warm white tone similar to halogen, avoiding the cooler blue-white cast of higher-Kelvin LEDs. Energizer rates the bulb for a 15-year lifespan based on average domestic use, significantly outlasting both halogen and incandescent equivalents.

Frequently Asked

What fitting does the B15 cap fit?

The B15 is the small bayonet cap, measuring 15mm across the base pins. It fits older British light fittings, many chandeliers, and period-style reproductions. The more common B22 bayonet cap is 22mm across and will not fit a B15 socket.

Is the bulb compatible with dimmer switches?

Yes. The bulb works with most leading-edge and trailing-edge dimmer switches. Performance varies depending on the specific dimmer model, so compatibility cannot be guaranteed across all installations. If the bulb flickers or fails to dim smoothly, the dimmer may need replacing with an LED-compatible model.

What does the 40W replacement rating mean?

The 5W LED produces 550 lumens, which is equivalent to the light output of a traditional 40W incandescent golf ball bulb. The LED achieves this using 87% less electricity.

How long does the bulb last?

Energizer rates this bulb for a 15-year lifespan based on average domestic use of 3 hours per day. Actual lifespan depends on usage patterns, operating temperature and how frequently the bulb is switched on and off.
