Endon Wisp E27 LED 4W Filament Bulb - 1800K - Non-Dimmable - Smoked Glass

A Filament Bulb Built to Be Seen

The Wisp is an E27 LED bulb with a decorative wispy filament design behind a smoked tinted glass finish. Running at 4 watts and 1800K, it gives off a warm, atmospheric glow that is meant to be looked at, not hidden away.

Smoked Glass Finish

The smoked tinted glass softens the light and gives the bulb a moody, amber cast, while the visible wispy filament adds texture and shape. Made from glass and steel, its large, sculptural silhouette suits fittings where the bulb itself is the star.

How It Works

The Wisp uses a 4W LED E27 fitting and produces 50 lumens, a lower output that suits ambient mood lighting rather than tasks like reading. It is not dimmable, so it works best in fittings without a dimmer switch. As a bulb rather than a complete fixture, it is designed to be fitted into your own pendant or wall light.

Where It Works Best

Its large scale and decorative filament make it best suited to exposed fittings, think open pendant lights or wall lights where the bulb is not covered by a shade. It is a good choice for anyone wanting a soft, warm accent glow rather than bright, functional light.

Made By Endon Lighting

Behind the Wisp's smoked glass and sculptural filament sits Endon Lighting, a British decorative lighting brand whose design heritage stretches back more than 80 years. A UK based design team shapes every collection, blending contemporary influences with timeless decorative styles so pieces like this filament bulb feel equally at home in a period setting or a thoroughly modern interior. That balance of heritage and current design thinking is what gives the Wisp its distinctive character.
