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.

Every Purchase Restores Sight

Dulora is a proud supporter of the Fred Hollows Foundation. Every order helps fund cataract surgery and eye care programs across Australia. A simple bulb purchase. A life-changing outcome for someone who has never been able to see clearly.

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 90+

Noticeably better light

Colours come back to life. Reds stay warm, skin tones look natural, and surfaces take on the depth and texture they were always meant to have. A significant step above what most homes and venues settle for.

Colour Temperature

An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four-digit number followed by (K), such as 2700K. High temperatures indicate white, "cooler" colours, while lower temperatures indicate yellower, "warmer" colours. Some typical Kelvin temperatures are 2700K (warm white) and 4000K (natural white).

2200 Kelvin
CRI

The Colour Rendering Index is an international system that rates a lamp's ability to render objects colours.

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.
