Sfera E27 clear bulb 4000 K 490 lm Ideal Lux

A clear bulb with a spherical profile

The Ideal Lux Sfera bulb combines a compact, recognisable shape with a clear finish that reveals the light source and enhances the fittings in which it is installed. The spherical format suits table lamps, pendant lights, wall lights and other solutions with an E27 fitting, especially when the bulb remains partly or fully visible.

With a height of 7.5 cm and a diameter of 4.5 cm, model 153957 suits fittings with compact proportions. Its small dimensions also help when choosing a bulb for light structures, multiple light points and decorative lamps where the source contributes to the overall appearance. The clear finish maintains a simple look and pairs with metal, glass or other materials without adding visual weight to the light point.

The 4 W power and 4000 K colour temperature produce clear light for rooms where crisp, less warm illumination is wanted. It can be used in a kitchen, study, hallway or contemporary living room with a compatible, suitably proportioned fitting. The Sfera shape also suits arrangements with several light points, where the clear bulb helps maintain a light visual presence.

Before buying, compare the fitting, overall size and power stated on the luminaire. This model is not dimmable, so use it with controls compatible with a fixed-output light source.

Usage advice

It takes bulbs with an E27 fitting, up to 4 W each: bulbs with the same natural colour tone give an even result. It is not dimmable; brightness depends on the bulbs installed. Installation must be carried out with the power disconnected and, if you have no experience, by an electrician.

Cleaning and maintenance

Carry out every task with the lamp switched off, cool and disconnected from the mains. Clean the glass parts with a soft cloth and, if needed, glass cleaner applied to the cloth, never directly to the lamp. To change a bulb, wait until it has cooled and do not exceed the maximum wattage shown on the label.
