Description

The JCB 4.9W LED golf ball bulb delivers 470 lumens of warm white 3000K light through a compact 45mm globe, fitted with a B15 small bayonet cap. The bulb replaces traditional 40W incandescent golf balls while drawing 4.9W, reducing energy consumption by 87% according to the packaging claim.

Designed for decorative fixtures with visible bulbs, the golf ball shape suits chandeliers, wall sconces, bedside table lamps and exposed pendant fittings where the bulb itself forms part of the aesthetic. The B15 small bayonet cap (SBC) is a smaller variant of the standard B22 fitting, commonly found in older British decorative lighting and compact European-style fittings. The 180-degree beam angle provides omnidirectional light distribution suitable for ambient rather than directional lighting.

The 3000K colour temperature sits in the warm white range, producing a yellowish tone similar to traditional incandescent bulbs rather than the cooler, bluer light of daylight LEDs. The bulb is non-dimmable and maintains consistent output on standard switched circuits. JCB rates the bulb at 10,000 hours life expectancy and includes a 10-year warranty period. The bulb carries an F energy rating under the updated EU energy label system introduced in 2021.

Frequently Asked

What is a B15 fitting and where is it used?

B15 is a small bayonet cap (SBC), a smaller version of the standard B22 bayonet fitting. It has a 15mm diameter base with two pins that twist-lock into the socket. B15 fittings are commonly found in decorative chandeliers, wall sconces, bedside lamps and older British light fittings where a compact bulb is needed.

Can this bulb be used with a dimmer switch?

No. The bulb is non-dimmable and will not work correctly on dimmer circuits. Use it only on standard switched lighting circuits.

What does the F energy rating mean?

The F rating refers to the updated EU energy label system introduced in 2021, which rescaled all bulbs onto a stricter A-G range. An F rating indicates moderate efficiency by current LED standards, though still far more efficient than the 40W incandescent bulb it replaces.

How does 3000K warm white compare to other colour temperatures?

3000K produces a yellowish warm white tone similar to traditional incandescent bulbs, warmer than neutral white (4000K) and much warmer than cool daylight (5000K-6500K). It suits living rooms, bedrooms and dining areas where a cosy ambient tone is preferred over task lighting.
