Description
This is a small golfball lamp on an E27 screw cap, with a white dome that spreads light right round the bulb rather than throwing it forward. It gives 470 lumens from 5W, a neutral white at 4000K that reads cleaner and brighter to the eye than a warm yellow bulb. The dome keeps the brightness even, so it looks calm sitting in an open shade or behind clear glass. It is not dimmable, so use it with a plain on and off switch.
We reach for bulbs like this for the workaday lights of a house: a landing pendant, a kitchen ceiling fitting, a utility room, a lamp on a desk. The cooler white suits work that needs clear sight, chopping, sewing, sorting paperwork, and it keeps white paint and white tiles looking white rather than creamy. The compact round body also helps in fittings where a longer bulb would peep below the rim of the shade. Stick to dry indoor rooms with it; a porch or a shower zone wants a sealed fitting instead.
The body is white, and the standard screw cap means it drops into most household holders without fuss. Clean it cold: turn the light off, give the glass time to lose its heat, then lift dust from the dome with a dry cloth and leave sprays and damp rags out of it. It carries a three year warranty. Sold as a duo-pack, so a spare sits in the drawer ready for the evening one goes dark, which is the sensible way to buy a bulb you use in more than one room.

Frequently Asked
How big is each bulb?
Each one measures 42mm across the dome and 69mm from the tip to the base of the cap, so it stays neatly inside small shades and glass domes.
Will it work with a dimmer switch?
No. It is a non-dimmable lamp, so it should be run from an ordinary switch. On a dimmer circuit you may see flicker or buzz, and the bulb will not see out its rated life.
How long should it last?
It is rated at 15,000 hours of average life, which for a hall or landing light used a few hours a night is several years of service.
What does 4000K look like in a room?
It is a crisp neutral white, brighter and less yellow than a 2700K warm lamp. It suits kitchens, utility rooms and task lamps, and pairs best with other 4000K bulbs rather than sitting alongside warm white ones in the same room.
Can I use it in a bathroom or outside?
It is rated IP20, so it belongs in dry indoor rooms. Bathroom zones and outdoor positions need a fitting and lamp rated for damp and wet conditions.
How many bulbs come in the pack?
Two, both the same white golfball lamp, so you can fit one and keep the other as a spare.
