Description
This is a golf ball LED bulb with an E27 screw cap, the larger of the two common screw sizes and the one usually called ES. It draws 4.9W and gives 470 lumens, which the retail pack rates as the equal of a 40W conventional bulb. The light is warm white at 3,000K, a soft yellow-toned white rather than a crisp one, and the opal envelope keeps the LED chips behind a smooth diffuser so you see an even glow rather than bright points.
A golf ball is the shape to reach for when a full-size GLS bulb looks too big for its holder. It suits small pendants, bedside and table lamps, wall lights and multi-arm fittings where several bulbs sit close together, and it works well in open shades where the bulb is on show. Warm white at 3,000K sits between the yellow 2,700K of an old filament lamp and the neutral 4,000K of a kitchen downlight, so it stays cosy in a living room or bedroom without turning amber. The pack gives the bulb as 45mm across and 80mm long, worth checking against a narrow shade ring.
This bulb is not dimmable, so put it on a plain on/off switch rather than a dimmer circuit. It runs on 220-240V mains, and the pack states a lamp life of 10 years or 10,000 hours along with more than 10,000 switching cycles, which matters on a hall or landing light that gets flicked on and off all day. The energy label rates it F, and the IP20 rating means indoor use in dry positions. One unit is a single boxed bulb, with a minimum order of 5 sold in multiples of 5. It sits alongside our wider range of LED golf and candle bulbs, which includes B15 (SBC) caps and cool white 4,000K and daylight 6,500K versions as well as this warm white.

Frequently Asked
How do I know if my lamp takes an E27 cap?
E27 is the larger screw fitting, 27mm across the threaded metal base, and is often marked ES on packaging. Unscrew the old bulb and compare the thread before ordering.
How bright is 4.9W against the old bulb I am replacing?
It produces 470 lumens, and the pack rates that as the equal of a 40W conventional bulb. Lumens, not watts, are what tell you the light output of an LED.
Can I put this on a dimmer switch?
No. It is non-dimmable, so use it on a standard on/off switch. A dimmer circuit is not a suitable control for this bulb.
What does warm white 3,000K actually look like in a room?
It is a soft, slightly creamy white, warmer than a 4,000K kitchen light but a shade cleaner than the deep yellow of a 2,700K filament lamp.
Will it fit inside a small shade or a narrow glass?
The pack gives it as 45mm in diameter and 80mm long overall, so measure the inside of the shade or glass and allow a little clearance around the bulb.
Is it suitable for an outdoor fitting?
No. It is rated IP20, which gives no protection against water or moisture, so keep it to indoor fittings in dry, sheltered positions only.
