Description

The Energizer 4W LED golf ball bulb uses exposed filament-style LED strips inside a clear glass envelope to mimic the appearance of a traditional incandescent bulb while running on modern LED technology. The B22 bayonet cap fits standard UK lamp holders, and the 45mm diameter golf ball shape suits compact fittings including bedside lamps, wall lights, and multi-bulb chandeliers where the bulb is visible.

At 2700K colour temperature the bulb emits warm white light comparable to a traditional 40W incandescent, producing 470 lumens with a wide 320-degree beam angle that distributes light evenly across a room. This suits living rooms, bedrooms and hallways where a softer, warmer tone is preferred over the cooler tones of daylight-rated LEDs. The non-dimmable design keeps the driver circuitry simple and reduces bulb cost compared to dimmable equivalents.

The filament effect comes from two vertical LED strips running inside the glass bulb, giving the appearance of a traditional filament when lit and when switched off. The clear glass envelope allows the filament detail to remain visible in open-shade fittings and exposed-bulb fixtures. Energizer rates the bulb at 15,000 hours lifespan under typical use, which equates to approximately 13 years at 3 hours per day.

Frequently Asked

Is this bulb dimmable?

No. The bulb is non-dimmable and should not be used with dimmer switches as this can cause flickering, buzzing or premature failure. If dimming capability is needed, search for the dimmable variant in the Energizer range.

What is the B22 cap size?

B22 is a bayonet cap with a 22mm diameter base, the standard fitting for most UK domestic lamp holders. The bulb pushes in and twists to lock, rather than screwing in like an E27 Edison screw bulb.

How does 470 lumens compare to traditional bulbs?

470 lumens is equivalent to a 40W incandescent bulb. This suits bedside lamps, hallway wall lights and decorative fixtures where moderate rather than intense light is needed.

Does the filament effect show when the bulb is off?

Yes. The two vertical LED filament strips inside the clear glass envelope remain visible when the bulb is switched off, maintaining the traditional filament appearance in exposed-bulb fittings.
