Description

The Energizer 4.2W LED golf ball bulb features an E14 small Edison screw base, 6500K daylight colour temperature and 470-lumen output. The compact golf ball shape measures 45mm diameter by 87mm height, fitting small table lamps, wall sconces, chandeliers and decorative fittings that take E14 bulbs. The 4.2W LED draws significantly less power than the 40W halogen bulb it replaces while producing equivalent brightness.

Designed for task-oriented spaces requiring high colour accuracy and alertness, the 6500K daylight output works well in kitchens, home offices, study desks, workshops and bathrooms. The cooler blue-white tone mimics natural daylight, supporting concentration and visual clarity during detailed work. The 140-degree beam angle provides wide light dispersion across a room rather than a focused spot, making the bulb suitable for general illumination rather than directional task lighting.

The LED is rated for a 15-year lifespan based on average domestic use of 3 hours per day, reducing replacement frequency compared to halogen or incandescent equivalents. The bulb operates on 230V mains power and is non-dimmable, delivering consistent output when switched on. The E14 screw base fits securely into compatible fittings without adapters.

Frequently Asked

What is the difference between 6500K and warmer bulbs?

6500K daylight produces a cool blue-white light that mimics natural daylight, supporting concentration and visual accuracy. Warmer bulbs at 2700K-3000K produce a yellow-white light similar to traditional incandescent bulbs, which most people prefer for relaxation areas like living rooms and bedrooms. Choose 6500K for task lighting in kitchens, offices and workshops where clarity matters.

Can this bulb be used with a dimmer switch?

No. This bulb is non-dimmable and will not respond to dimmer switches. Attempting to use it with a dimmer may cause flickering, buzzing or premature failure.

What is the E14 base size?

E14 is the small Edison screw, measuring 14mm diameter at the threaded base. This is the smaller of the two common UK screw bases — the larger is E27 at 27mm. E14 is used in compact table lamps, wall lights, chandeliers and decorative fittings where space is limited.

How long does the 15-year lifespan last in real terms?

The 15-year rating assumes 3 hours of use per day. If the bulb runs for 6 hours daily, expect approximately 7.5 years. If used only 1.5 hours daily, it may last 30 years. The total rated life is approximately 16,425 hours.
