The Original Filament

The Edison form is where decorative LED lighting began. The teardrop silhouette and looping filament are instantly recognisable, carrying a century of design history into spaces that value character over convention. In an exposed pendant or industrial fitting, nothing else comes close.

Where It Belongs

There is a reason the world's most loved bars, restaurants, and creative studios reach for the Edison bulb when they want a space to feel alive. The visible filament and amber warmth create an atmosphere that is immediately readable as somewhere worth being. At home it transforms a kitchen pendant or a bedside lamp from a functional object into a focal point. It does not just fill a space with light. It gives the space a character that people feel before they can name it.

See the Difference CRI Makes

Standard CRI 80+

Dull, washed-out light

Reds lose their warmth. Skin looks pallid. Artwork loses depth. The room feels lifeless regardless of how many bulbs you use.

Dulora CRI 97+

Rich, accurate light

Every hue appears exactly as intended. The same room, transformed. Not brighter, but alive. This is what your space was always meant to look like.

Product Features

Adjust the brightness to create the perfect mood – from cosy evenings to bright, functional light.

Gentle on the eyes – no strain, fatigue, or headaches.

Gentle warm tone, replicating classic vintage Edison-style bulbs.

Efficient LED equivalent to a classic 40W incandescent bulb.

Exceptional colour fidelity – museum-grade light that reveals every subtle detail.

Description

An amber glow with visible filament detail, designed to be seen. The 4.2W Edison LED Bulb delivers 470 lumens of rich 2200K extra warm light from the iconic ST64 shape, replacing a traditional 40W incandescent at a fraction of the energy. The clear glass finish showcases the LED filament array in the styles of a classic squirrel-cage Edison, with ultra-high colour accuracy ensuring colours and textures look warm and true. Backed by a 3-year warranty.

The Clear Glass Effect

Clear glass is central to the Edison aesthetic. Rather than hiding the light source behind a frosted or coated surface, it puts the LED filament array on full display, creating visible warmth, sparkle, and detail that suit decorative and exposed-bulb installations. The 2200K extra warm colour temperature adds a deep amber tone that sits closer to candlelight than standard warm white, giving the globe a nostalgic character that works whether it is hanging solo in a pendant or grouped across a multi-lamp fixture. Pair it with a compatible trailing-edge dimmer for smooth, flicker-free control from full brightness down to a soft, intimate glow.

Where It Belongs

The 4.2W Edison in E27 fits the most widely used screw base globally, making it a versatile choice across residential and commercial projects. In the home, it brings character to pendant lights, floor lamps, exposed-socket fixtures, and open-plan living areas where the globe is fully visible. In hospitality and commercial settings, it suits café and bar fit-outs, restaurant feature pendants, boutique hotel lobbies, and retail spaces where decorative warmth is part of the brand experience. For designers and electricians specifying across different projects, the E27 base ensures broad compatibility with most decorative fittings.

Frequently Asked Questions

Why should I choose CRI 95+ LED bulbs over standard CRI 80?

Standard bulbs often make interiors look grey or "muddy" because they lack depth in the colour spectrum. Our CRI 95+ collection provides "True Colour" light that is almost indistinguishable from natural daylight, making your furniture, artwork, and skin tones look vibrant and accurate.

Do these high CRI bulbs have a high R9 value for reds?

Yes, our CRI 95+ range is specifically engineered with high R9 values, which is the specific metric for rendering deep reds. This is essential for bringing out the rich grain in timber flooring and ensuring skin tones look healthy rather than washed out under artificial light.

Are these high-quality LED bulbs flicker-free?

Absolutely. We use advanced constant-current drivers within our bulbs to ensure a flicker-free performance that is gentle on the eyes. This reduces the risk of eye strain and headaches, which are common issues with cheaper, low-quality LED alternatives.

Will these CRI 95+ bulbs work with my existing dimmer switches?

These bulbs are fully dimmable and designed to be compatible with most modern trailing-edge LED dimmers. To ensure the smoothest dimming range without buzzing, we always recommend checking that your dimmer switch is rated for low-wattage LED loads.

Can I use these bulbs in art galleries or high-end retail displays?

Yes, our CRI 95+ collection is the preferred choice for galleries and boutique retail where colour precision is non-negotiable. The high fidelity ensures that products and paintings are viewed exactly as the artist or designer intended, with no artificial colour shifting.

These bulbs have a nice warm tone, without being too dull. They appear to be very well made, were packed well and arrived quickly. I am very impressed, this being my first purchase of fancy LED bulbs.

Response and dispatch was fantastic, however your freight company needs to take more care with your goods. One package we received was in good shape but the other one was damaged and in result when it was unwrapped had a broken light. Your response was awesome as you covered the replacement immediately, it was the inconvenience of time that hurt as we needed to hand over the job minus a globe.

Fantastic!
