Description

The Energizer LED Golf Ball is a 4.2W LED bulb with a B15 small bayonet cap base, producing 470 lumens at 2700K warm white. The compact golf ball shape measures 45mm diameter by 87mm height, fitting standard table lamps, wall lights and decorative fittings that take B15 bulbs. The frosted glass envelope diffuses light evenly across a 140-degree beam angle.

Designed as a direct replacement for 40W incandescent golf ball bulbs, this LED consumes 4.2W while delivering equivalent brightness, reducing energy use by approximately 90%. The 2700K colour temperature produces a warm, yellowish light similar to traditional tungsten bulbs, suitable for living rooms, bedrooms and lamp bases where softer ambient lighting is preferred over cooler task light. The bulb is rated for a 15-year lifespan based on average domestic use of 3 hours per day.

The B15 small bayonet cap uses a 15mm diameter base with two pins, distinct from the more common B22 22mm bayonet. Check your existing bulb base before ordering — if the metal cap is noticeably smaller than a standard bayonet bulb, it's likely B15. The bulb is non-dimmable and should be used only on standard on/off switches; fitting it to a dimmer circuit will cause flickering or failure.
