Description

The Energizer LED Golf Ball is a 4.2W E27 bulb delivering 470 lumens at 6500K daylight white. The golf ball shape (45mm diameter, 87mm total height) fits compact fittings where a full-size GLS bulb would protrude, and the Edison screw base threads into standard UK lamp holders. The non-dimmable LED runs at a fixed output of 470 lumens from switch-on, with no warm-up time and no compatibility issues with dimmer circuits to navigate.

Designed for utility areas, home offices, kitchens, bathrooms and garages where cool-toned task light is needed, the 6500K colour temperature renders colours with higher blue content than warm white bulbs, making it well-suited to detailed work, reading small print and areas where daylight simulation is preferred. The 140-degree beam angle provides a wide spread of light from a downward-facing or semi-recessed fitting. At 4.2W the bulb replaces a traditional 40W incandescent while drawing approximately 90% less energy.

The bulb carries an Energy Rating of E and a rated 15-year lifespan based on average domestic use of 2.7 hours per day. The frosted golf ball diffuser eliminates visible LED hotspots and provides even light distribution. At 20g the bulb is light enough for pendant fittings and wall brackets where heavier halogen equivalents might stress the fixture over time.

Frequently Asked

What does 6500K daylight white mean in practice?

6500K is a cool white with a blue tint, similar to overcast daylight. It appears noticeably cooler than the warm yellows of 2700K-3000K bulbs. This colour temperature is preferred in workspaces, garages and utility areas where task visibility matters more than ambient warmth.

Can this bulb be used in enclosed fittings?

Yes. The low heat output of the 4.2W LED makes it suitable for fully enclosed fittings where traditional incandescent bulbs would overheat. Check the fitting's maximum wattage rating to confirm compatibility.

What is the golf ball shape used for?

Golf ball bulbs are compact spheres (45mm diameter) used in smaller fittings where a standard GLS bulb would be too large. Common applications include bedside lamps, wall brackets, chandeliers with multiple arms, and decorative fittings with visible bulbs.

Why is it non-dimmable?

Non-dimmable LEDs use simpler driver circuitry, making them more affordable and reliable for fixed-output applications. If fitted to a dimmer circuit the bulb may flicker, hum or fail prematurely. For dimming, a dimmable-rated LED is required.
