YOUDIAN 4W LED Edison Bulb 2700K

The essentials

The YOUDIAN LED Edison bulb brings a vintage aesthetic to modern lighting. With a warm 2700K amber glow, these ST64 style bulbs create a cosy ambience while consuming a fraction of the energy of traditional incandescent lamps. Each bulb uses a 4W LED filaments design and fits an E27 base, making them suitable for chandeliers, pendant lights, and decorative fixtures. Built to operate on 220–240V, they promise a steady, flicker-free light that stays gentle on the eyes over long periods 😌. The amber glass and retro silhouette evoke timeless interior style without compromising on efficiency or safety.

In daily use they excel in residential and hospitality settings where atmosphere matters as much as practicality. The design reduces glare and emphasises a warm, even spread that faithfully renders colours. By choosing these bulbs you can lower energy bills while retaining a classic look that suits bars, cafes, living rooms and dining spaces. The LEDs are mercury-free and encased in high-quality amber glass, offering durability and peace of mind for continuous use.

Technical details

The bulbs are engineered to replace a 40W incandescent equivalent, delivering significant energy savings of around 90% while maintaining brightness appropriate for decorative lighting. With a long life of about 30,000 hours, you can enjoy years of maintenance-free operation. The E27 screw base is compatible with a wide range of fixtures, and the 2700K warmth remains constant over time. No ultraviolet or infrared radiation means safer light for sensitive eyes and surfaces. The vintage style is enhanced by a classic ST64 shape and a robust construction designed for both indoor and sheltered outdoor use in suitable luminaires.

In terms of safety and comfort, the bulbs use lead-free materials and stringent filtration to minimise flicker. The retro amber glass not only looks appealing but also provides a regal diffusion that flatters architectural details and textures. Consider pairing these bulbs with dimmable fixtures if supported, to further tailor the mood to occasions or daylight levels.

Who it’s for

Worth noting if you’re decorating a space with a nostalgic flair, these bulbs are ideal for ceiling fixtures, chandeliers and pendants in homes, hotels, and cafés. They suit vintage-inspired interiors as well as contemporary rooms seeking a warm focal point. If you value energy efficiency without sacrificing character, these bulbs offer solid value for money and dependable performance over time. You’ll appreciate the balance between classic aesthetics and modern LED reliability, making them a practical upgrade for legacy fittings while keeping maintenance simple.
