Linear by Design

The tubular form brings a clean, architectural quality to spaces that demand something beyond the ordinary globe. Elongated, precise, and visually distinctive, it works as a statement piece in bare filament pendants, bathroom mirror bars, and any fitting where the bulb itself is part of the composition.

Where It Belongs

Run three tubular bulbs above a bathroom mirror and the room shifts from functional to considered in a single decision. Line them above a kitchen benchtop or hang a single long tube in a narrow corridor and the effect is the same: clean, architectural, deliberate. Interior designers and hospitality fit-out teams specify the tubular form because it brings a graphic quality to a space that rounder bulbs cannot. It is lighting that communicates that someone thought carefully about every detail.

Sehen Sie den Unterschied, den der CRI macht

Standard CRI 80+

Trübes, ausgewaschenes Licht

Rottöne verlieren ihre Wärme. Die Haut wirkt blass. Kunstwerke verlieren an Tiefe. Der Raum wirkt leblos, ganz gleich, wie viele Glühbirnen Sie verwenden.

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.

Produktmerkmale

Klassischer Glühlampen-Look – sanft, gemütlich und einladend.

Beschreibung

Ein langer, glatter, weißer Tubus, der von einem Ende bis zum anderen leuchtet, statt durch ein sichtbares Bauteil im Inneren. Die dimmbare 4-W-LED-Langröhrenlampe E27 aus Porzellan liefert 300 Lumen warmweißes Licht mit 2700 K in einer E27-Fassung und ersetzt eine herkömmliche 30-W-Glühlampe mit äußerst hoher Farbwiedergabe. Die vollständig undurchsichtige Porzellanbeschichtung verbirgt alles im Inneren und verwandelt die gesamte Länge von 290 mm in eine einzige, gleichmäßige Lichtquelle. Mit 3 Jahren Garantie.

Der Porzellaneffekt

Die Porzellanbeschichtung lässt jede Spur des LED-Arrays verschwinden und verteilt das Licht gleichmäßig über die gesamte Länge des Tubus – ohne Hotspots, Helligkeitsschwankungen oder sichtbare Details aus irgendeinem Blickwinkel. Das Ergebnis erinnert eher an einen leuchtenden Stab als an eine herkömmliche Lampe: eine gleichmäßige Säule warmen Lichts, die sich sanft um die Fassung legt, statt von einer sichtbaren Lichtquelle auszustrahlen. Im ausgeschalteten Zustand verleiht die glatte, mattweiße Oberfläche dem Tubus eine skulpturale, fast keramische Qualität. Er wirkt auch im ausgeschalteten Zustand bewusst gestaltet und eignet sich besonders für offene Pendelleuchten und Installationen mit sichtbaren Leuchtmitteln, bei denen der Tubus zum Raum beitragen soll. Durch die Länge von 290 mm tritt dieser Effekt stärker hervor als bei kürzeren Porzellanvarianten, da einfach mehr leuchtende Oberfläche sichtbar ist. Ein Phasenabschnittdimmer ermöglicht eine gleichmäßige Reduzierung der Helligkeit mit flimmerfreiem Betrieb über den gesamten Dimmbereich.

Der passende Einsatzort

Moderne Pendelleuchten-Gruppen, minimalistische Kronleuchter und offene Leuchtendesigns sind Einsatzbereiche, in denen ein langer, gleichmäßig beleuchteter Tubus besser zur Gestaltungsidee passt als ein sichtbarer Filamentfaden. Im gewerblichen Bereich eignen sich Boutique-Einzelhandel und Gastronomie- sowie Hotellerieeinrichtungen, die ein skulpturales Beleuchtungskonzept mit einigen sichtbaren Leuchtmitteln umsetzen. Auch Galerien und Ausstellungsräume, in denen schattenfreies, gleichmäßiges Licht wirklich erforderlich ist, sowie Spa- und Wellnessbereiche, die ein ruhiges, diffuses Leuchten statt eines funkelnden Lichts wünschen, sind ideale Einsatzorte. Moderne Badezimmer-Spiegelleuchten, Pendelleuchten im Schlafzimmer und Wohnbereiche, die entlang eines langen, schlanken Profils gleichmäßiges warmes Licht benötigen, sind natürliche Anwendungsbereiche.

    2700 Kelvin
  • CRI

    The Colour Rendering Index is an international system that rates a lamp's ability to render objects colours. The higher the CRI (based upon a 0-100 scale), the richer and more accurately the colours appear. CRI differences among lamps are not usually visible unless the difference is more than 3-5 points.

  • Dimmbar

    Indicated whether a product can be dimmed in conjunction with a suitable dimmer control.

    Yes, with most incandescent and LED dimmers.
  • Augenkomfort

    Eye comfort measures how stable and consistent a bulb's light output is. Even when invisible to the naked eye, flickering light can cause headaches, eye strain, and fatigue, particularly during extended periods of reading, working, or relaxing at home. Dulora's dimmable globes are independently tested by TÜV Rheinland and meet internationally recognised low-flicker standards at full brightness. For the best experience, pair with a quality LED dimmer, as flicker performance can vary depending on the dimmer used.

Frequently Asked Questions

How bright are Dulora bulbs?

LED brightness is measured in lumens, not watts. Here's a quick conversion guide:

  • 2-3W LED ≈ 25W incandescent (200-300 lumens)
  • 4-5W LED ≈ 40W incandescent (400-500 lumens)
  • 6-8W LED ≈ 60W incandescent (650-800 lumens)
  • 7.5-10W LED ≈ 75-100W incandescent (900-1200 lumens)
  • 11-12W LED ≈ 100-125W incandescent (1300-1500 lumens)

All Dulora product pages list wattage and lumen output so you can choose the perfect brightness for your needs.

What countries do you ship to?

Dulora bulbs are designed for over 25,000 hours of use. If you use your light for an average of 3 hours per day, your LED bulb could last over 22 years. This exceptional longevity significantly reduces the frequency of replacements compared to traditional incandescent bulbs, which typically last only 1,000-2,000 hours. Note that all LED bulbs' light output gradually decreases over time, a phenomenon known as lumen depreciation.

Are Dulora bulbs dimmable?

Yes, most Dulora bulbs are dimmable, allowing you to create the perfect ambience for any occasion. Look for the "dimmable" specification on the product page. For optimal performance, we recommend using LED-compatible dimmers. Some older dimmer switches may cause flickering or buzzing with LED bulbs. If you experience any issues, please contact our customer support team for assistance.

What is colour temperature, and which should I choose?

Colour temperature refers to the warmth or coolness of light, measured in Kelvins (K):

  • Ultra & Extra Warm (2000K-2200K): This calming light creates a relaxing ambiance, similar to the warm glow of candlelight.
  • This calming light gives off a warm glow, similar to candlelight. However, because it is such a soft light, it may not be suitable for activities that require focus, such as reading.
  • Warm White (2700K-3000K): This colour creates a cozy, inviting atmosphere similar to traditional incandescent bulbs. It is ideal for living rooms, bedrooms, and dining areas.
  • Natural White (3500K-4000K): Provides a balanced, neutral light perfect for kitchens, offices, and workspaces.
  • Cool White (5000K-6500K): This colour delivers a crisp, energising light similar to daylight. It is best for task lighting, garages, and areas requiring detailed visibility.

Choose based on the mood you want to create and the purpose of the space.

Are Dulora bulbs compatible with my existing fixtures?

Dulora offer bulbs in all standard base types, ensuring compatibility with most fixtures. Common bases include:

  • E27/ES: Standard Edison Screw, the most common base type (27mm diameter)
  • B22/BC: Bayonet Cap, standard in many regions (22mm diameter)
  • E14/SES: Small Edison Screw, used in chandeliers and smaller fixtures (14mm diameter)
  • B15/SBC: Small Bayonet Cap, used in smaller fixtures (15mm diameter)
  • E12/SES: Mini Edison Screw, used for chandeliers and small fixtures from the US (12mm diameter)

Check your existing bulb's base type and match it with the corresponding Dulora product. If unsure, take a photo of your current bulb base and contact our customer service team for assistance.

Can Dulora bulbs be used in enclosed fixtures?

Some Dulora bulbs can be used in enclosed fixtures, but not all. Look for the "enclosed fixture compatible" specification on the product page. Enclosed fixtures trap heat, which can shorten LED lifespan if the bulb isn't designed for such applications. Our enclosed fixture-compatible bulbs feature enhanced heat dissipation technology to maintain performance and longevity even in enclosed environments. For fixtures without proper ventilation, we recommend choosing bulbs specifically rated for enclosed use.

What is the difference between clear, frost, opal, and porcelain LED bulbs?
  • Clear LED bulbs have a transparent glass covering that showcases the filament inside, creating a decorative, vintage appearance. They produce more directional light and create beautiful shadow patterns.
  • Frost, opal, and porcelain LED bulbs diffuse light, reducing glare and distributing illumination evenly. These bulbs are ideal for ambient lighting and minimising shadows when fabric or glass shades are used. Frosted bulbs allow good light transmission but with slightly visible LED filaments. Opal and porcelain bulbs provide uniform light diffusion and better LED concealment. Opal bulbs have a shiny finish, while porcelain bulbs have a matte finish.

Choose clear bulbs for decorative fixtures where the bulb is visible and frosted, opal or porcelain bulbs for everyday lighting where comfort and light distribution are priorities.

How much energy do Dulora bulbs save compared to traditional bulbs?

Dulora bulbs use up to 90% less energy than traditional incandescent bulbs while providing the same brightness level. For example, a 6.5W GLS LED bulb produces the same light as a 60W incandescent bulb. This significant energy reduction translates to lower electricity bills and a smaller carbon footprint. Over the bulb's lifetime, you can save hundreds of dollars in energy costs per bulb.

What is your warranty policy?

Dulora bulbs come with a comprehensive warranty against manufacturing defects. Most of our products carry a 2-year warranty, while premium lines may offer extended 3 to 5-year coverage. If your product fails during the warranty period under regular use, we'll replace it free of charge. Simply contact our customer service team with your order number and a description of the issue. Our no-quibble guarantee ensures a hassle-free experience if you encounter any problems.

Could see the led inside

I love the matte white glass, but unfortunately the element /led part is sort of floppy inside and touches the side of the glass so it’s very bright line where it touches.

Hi Louise,
Thank you for sharing this feedback. Can you please email photos or video to help@liquidleds.com.au of the light bulbs in your fitting showing the issue?​

Hello Katherine,
Thanks for leaving us a 5-star feedback. Look forward to your next visit. Have a great day!

Long tube led bulb

The globes look good plus they arrived in appropriate time. Will look good in the antique light when we have had the light fixed. The only issue i have is that 2 of the 3 lights rattle as if something is loose inside. I just wonder how long they will work for.

Thank you for sharing, Ross. We are thrilled that your experience was seamless and that you're enjoying your antique light. The rattling inside the bulb is the thin wires that are folding the LED filament in the correct position. If you check the long clear tubular bulb you will see the wires supporting the yellow filament. Have a great day!
